The refrigerator inspection methods and standards

Some fruits, drinks and meals in our life need to be placed in the refrigerator under certain circumstances, which can not only reduce the waste of food but also maintain their freshness. Therefore, the refrigerator plays a great role in our life.  So the refrigerator inspection and detection is particularly important.  So how to inspect the refrigerator?  This article will reveal the refrigerator inspection methods and standards, so that you no longer blindly receive goods.

I. Acceptance standard of refrigerator

1. Check the outer packing box first

Outer packing box corners should be complete and straight;  The packing belt shall not be too loose, and the groove edge of the packing belt on the surface of the packing box shall be straight and complete without depression;  There should be no abnormal perforation or large depression on the surface of the box.

2. Open the outer packing box

Check whether the plastic bags outside the machine are flat and have no abnormal folds, no damage, and no gray dust (the black ones are usually caused by electrostatic adsorption of plastic bags during transportation, which is a normal phenomenon);  The packaging foam of the base should be intact and clean, with no dust in the surface or crevices.

After opening the external plastic bags, check the surface paint of the machine should be shiny and bright, without scratches, pits, and no traces of collision and extrusion on the surface. Especially, the lower part of the refrigerator should be inspected to prevent deformation and damage caused by rough loading and unloading. The sealing tape on the refrigerator door should be intact and clean without stains.  The crevices should be free of dust.  The power cord should be neatly tied and the plug should be free of dirt and oil.  There should be no signs of removal of the fixing screws anywhere.  The gap between the upper and lower door frames of the refrigerator should be even, and the door seal should be smooth and free of dirt and damage (You can put a piece of paper in the door seam, and the door should not be able to move up and down after closing, indicating that the door is closed well. You can also find a flashlight to open it and put it in the refrigerator. After closing the door, check whether there is light coming out from the door seam (it is best at night).

3. Check the inside of the machine

The inside of the machine should be clean and tidy without foreign bodies, the manual bag should be flat without wrinkles and damage, each adjusting knob should operate flexibly without stuck, and the parts (attached) should be complete without shortage or damage.

4. Power test machine

Power test machine, the refrigerator should have no abnormal noise, vibration, power for about 10 minutes should be able to feel the heat side of the temperature rise, there should be an obvious feeling of freezing inside, dip your finger in a little water to contact the coil tube of the freezer room should have the feeling of finger sticking.

5, the installation is smooth

If all the above checks pass, you can ask the installer to install it in the location you specify.  Remember to ask the installer to install the refrigerator smoothly by shaking it from side to side.

6. Other checks

(1) The appearance of the machine has no damage, and the outer package is complete and unsealed.

(2) The instruction manual, warranty card and qualification certificate are complete, and the sealing of the plastic bag has not been opened.

(3) The list of attachments on the manual is complete in kind.

(4) There is 3C label on the product and energy efficiency ratio label on the refrigerator housing.

(5) Power test machine, the refrigerator temperature control setting is the lowest, after half an hour with a wet towel dipped in the liner will feel sticky.

Of course, the model number of the goods should be the same as the invoice.


The refrigerator

Two, the solution to the common refrigerator fault

1, the refrigerator is not refrigeration: the refrigerator power plug is plugged in;  Whether the power socket is powered on;  Whether the power circuit breaker is disconnected.  Check that the refrigerator door light is on to ensure that the refrigerator is powered on.  Check whether the thermostat is in working gear. The thermostat has stop gear (0). The compressor will not work when it is in stop gear.  If the above items are normal, please contact maintenance personnel.

2, the refrigerator refrigeration is poor: check whether the thermostat gear is too low.  Whether the food is overstored or overheated.  Whether the door is opened frequently or sealed loosely.  Whether there is direct sunlight or a heat source near the refrigerator.  Whether the surrounding ventilation is poor.  Check whether the ambient temperature is too low and the temperature compensation switch is not turned on.

3, the refrigerator has a sound can not start: under the normal environment temperature condition (15℃-38℃), when the refrigerator starts, if the compressor makes a "buzz" sound, the compressor stops working for about half a minute, this situation is due to the power supply voltage is too low (less than 187V) caused by the compressor can not start;  If the compressor emits a "um" sound, then hear a "patter" sound, this situation is caused by the power supply voltage is too high (higher than 242V) or the continuous working time of the compressor is too long;  When the power supply voltage returns to normal or the compressor casing temperature decreases, the refrigerator can work normally.

4, the door seal is not strict: the main reason for the gap between the refrigerator door seal and the box is the deformation of the door seal. The hair dryer (power 300W) can be used to blow the deformation of the concave part, so that it can be restored to the original state and the gap can be eliminated.  But pay attention to the power of the hair dryer can not be too large, the hot spot can not be too concentrated, the hair nozzle can not be too close to the deformed door seal, otherwise it will damage the door seal.  In addition, under the depression of the door seal and the door of the joint pad a thin sponge, can also eliminate the gap.  If the above correction is invalid, a new rubber strip should be replaced.

5, cold room water or overflow: cold room drainage hole blocked, resulting in condensed water can not be discharged smoothly, with a certain flexibility of tools to dredge.

Three, refrigerator appearance inspection

(1) Definition

1. Inclined plate: the inclined plate of the compressor chamber.

2, side plate: the box and the top, (bottom) of the board surface.

3. Beam: The horizontal plate on the front of the refrigerator is called beam.

4. Rear plate: the rear panel of the box.

5. Labyrinth groove: the front width of the box mouth frame is 20±0.5mm. The mouth frame strip is the front labyrinth groove.  The rear frame bar with a width of 6±0.5mm is the rear labyrinth slot.

6. Specific color difference: the color difference of the test object compared with the color pattern under natural day light or artificial light source.

7. Pure color difference: Color difference compared between objects in natural day light or artificial light source.

(2) Refrigerator appearance inspection

1. According to the visible difficulty and importance, the appearance of refrigerator can be divided into four levels: A, B, C and D

Zone A: Very important appearance.  An appearance that is visible at a glance or highly valued when standing.  Including: door panel, door cover cover, the outer surface of the display panel, the front surface of the top cover plate, the outer surface of the side panel, the front of the box.

Zone B: Important facade.  People are easy to see, more attention to the appearance of the surface.  Including: the outer surface of the inner liner of the door body, the door shelf, the side and bottom of the inner liner of the box, the surface of the drawer, the appearance of the door seal, the outer surface of the ceiling lamp, the outer surface of the temperature controller, the ice box, the small door of the freezer, the trelliss, etc.

Area C: The more important exterior surface.  Including: the front of the tank, the back plate of the tank, the condenser surface (external hanging), the surface of the wire tube evaporator.

Area D: The general requirements of the appearance surface include: compressor hood, electrical junction box.

2, refrigerator appearance requirements

3. The top cover, side panel, back panel, door panel and visible surface parts of the refrigerator should be clean, without stains, oil stains and other dirt affecting the appearance, and no white traces of wax powder and detergent are allowed to remain.  The compressor installation space is not allowed to have obvious oil, dust and bubble.

4. Inspection method: Wipe the top cover, side panel, back panel, door panel and any part of the visible surface of the refrigerator with a clean white rag. There should be no visible stains on the white rag.  In the installation space of the compressor, visible oil, dust and bubble should not be visible.

5. The appearance inspection standards of trial-made products not mentioned in this standard shall be based on the products sealed together by relevant product development department, production planning Department, quality and technology department, etc.

Final Random Inspection (FRI)

FRI takes place when the merchandise is 100% completed and at least 80% are well packed, marked and ready for shipment. Our inspectors randomly draw some samples from finished goods, based on statistical random sampling technique, commonly known as ANSI/ASQ Z1.4, MIL-STD-105E, BS6001, DIN40080, ISO2859 OR NFX06- 022, to verify that the finished shipping lots conform to your specifications. In general Qty check Style, color & material Visual check(workmanship) Function,safety check.
We would like to suggest client to booking this inspection at least 3 days before loading so that if some quality problems were found by inspector, clients will still have time to ask factory to re-work.

Pre-production Inspection (PPI)

A visual check on the quality of components, materials, and accessories at the beginning of production against clients' specifications and/or reference sample. The PPI thus permits timely corrections and improvements before the mass cargo will be manufactured, any non-conformity is immediately reported so as to avoid delay in shipment. In general, we will check the following aspects for PPI:
Evaluate the production status during the manufacturing process
Randomly inspect the finished samples on-site and compare them with your product spec
According to the evaluated status of finished and semi- finished samples, rearrange the QC layout in the factory.
Evaluate the packing details and packing material
Check the accuracy of production equipments and disposal methods for defective goods

100% inspection (Full Inspection)

When the merchandise is 100% completed, we will check the quality of goods unit by unit, which covers product description, style &color, workmanship, quality, function, label, package, size measurement if available etc, to make sure 100% of the goods meet your specified quality requirement. Note: for those products of high value or complicated internal structure, we suggest to take full inspection.

Container Loading Supervision (CLS)

Before loading, our inspector will check products' information, qty, package, during the course of loading, our inspectors will keep closely look at the loading process, ensure that the export cartons are well arranged in the container with no risks of deformation, collapse, help manufacturer finish loading under correct and clear working clauses and working process. In general:
Record the weather/arrival time of container/No./truck No Check the inner/outer condition to see if there is any
damage/wet/hole/peculiar smell Check the qty of goods loaded and record the condition of outer packaging(master cartons/pallets).Randomly draw and open some cartons to verify that the goods meet with clients' specification Supervise the whole loading process.Seal the container with the custom's seal and unique quality inspection's seal Record the seal No. and departure time of container.

Random Inspection

(Pre-production Random Inspection, During Production Random Inspection, Pre-shipment Random Inspection) As per customer's quality requirement, we will sample the products according to international or other standards to inspect the packing, appearance, color, size, function, safety, etc.
Purpose of Pre-production Random Inspection: To help know the production status & raw material quality and avoid any mistake on quality standard, order quantity and make sure that the order is arranged;
Purpose of During Production Random Inspection: To help know the production status & product quality during production and avoid any mass quality problem & abnormal production situation;
Purpose of Pre-shipment Random Inspection: To know the finished products quality & quantity and avoid any mass quality problem & shortage shipment.

What do our QC inspectors (quality inspector) do for the inspections ?

1. Confirm the quantity of the products.

2. Confirm the packing detail information of the products.

3. Check the information or marks reqiured by clients, such as the information on the carton, information on gift box, information
on products, warning text and all the others.

4. Check the overall appearance of the product.

  • What testing is required for my product?

    Regulatory laws and guidelines are an increasing challenge to importers through the world. How these affect you will vary widely based on your product type, component materials, where the product is being shipped, and the end-users in your market. Since the risk is so high, it is imperative you stay up to date on all relevant regulatory laws affecting your products. YONGSHUN staff can work with you to determine your exact requirements and propose a custom solution to best meet your needs. We also provide monthly updates on regulatory matters to keep our customers informed. Feel free to use the contact form to get on our newsletter list.
  • How can I get updates on regulatory issues?

    YONGSHUN takes great pride in our technical brain trust. They are constantly updating our internal knowledge base so we are prepared to proactively inform our customers on issues affecting their products. In addition, each month we send out our Product Safety and Compliance Update. This is a comprehensive view into the latest industry and regulatory changes and recall review that helps you make critical decisions. We invite you to join our list of recipients. Use the Contact Us form to get on the list to receive it.
  • Is package testing necessary for all products?

    Package testing is mandated by regulations for some products such as; food, pharmaceuticals, medical devices, dangerous goods, etc. This may cover both the design qualification, periodic retesting, and control of the packaging processes. For unregulated products, testing may be required by a contract or governing specification. However, for most consumer goods, package testing is often a business decision involving risk management for factors such as:

    • cost of packaging
    • cost of package testing
    • value of package contents
    • value of good will in your market
    • product liability exposure
    • other potential costs of inadequate packaging

    YONGSHUN staff would be happy to assess your specific product and packaging requirements to help you determine whether package testing can improve your quality deliverables.

  • How can California Prop 65 affect my business?

    Prop 65 is the 1986 voter-approved Safe Drinking Water & Toxic Enforcement Act that includes a list of Chemicals known to the State of California to cause cancer and/or reproductive toxicity. If a product contains a listed chemical, then the product must contain a “clear and reasonable” warning label informing consumers of the presence of the chemical and stating the chemical is known to cause cancer, birth defects, or other reproductive harm.

    Although companies with fewer than 10 employees are exempt, if they sell a violative product to a retailer with more than 10 employees, the retailer could receive a notice of violation. In these circumstances, retailers usually rely on clauses within their contacts with importers that require the importer take responsibility for the violation.

    A plaintiff may seek injunctive relief requiring a company caught selling a violative product to suspend sales, conduct a recall, or reformulate the product. Plaintiffs can also obtain penalties of up to $2,500 per violation per day. A more general California statute allows most successful plaintiffs to recover their attorneys’ fees as well.

    Many are now choosing to rely on 3rd party testing companies to verify that hazardous substances are not being used in their products.

  • How can my products meet regulatory requirements for hazardous chemicals?

    The simplest way is to engage a 3rd party testing company, such as YONGSHUN. Some manufacturers self-test and/or rely on local testing labs for certifying their products. However, there is no guarantee these labs, or their equipment, are reliable. Nor is there any guarantee the results are accurate. In either case, the importer may be held responsible for the product. In view of the risk, most companies opt to use a 3rd party testing lab. YONGSHUN’ 80,00 sf laboratory is centrally located in Hangzhou China, and does a broad range of consumer goods for all regulatory testing requirements.
  • What should I know about my supplier?

    Doing business in Asia can be a tricky and expensive effort if sufficient due diligence is not done for a supplier. How much is required may depend on your buyer’s requirements, your personal commitment to social compliance, and other business needs. YONGSHUN provides supplier evaluations and factory audit services from simple evaluation to complex technical and social compliance audits. YONGSHUN staff can work with you to determine your exact requirements and propose a custom solution to best meet your needs.
  • Why is a factory audit or supplier evaluation important?

    Do you REALLY know who you are buying from? Do you REALLY know what their production capabilities are and whether they can produce what you expect? These are important questions when assessing a potential vendor. Asia is ripe with middlemen, sub-contracting, materials and component swapping, fraudulent certifications and licensing, and sub-standard facilities, materials, and equipment. The only way to be sure who your supplier is and what his capabilities are, is to do an onsite evaluation or audit. YONGSHUN has experienced professional staff that are ready to conduct your factory audit supplier evaluation. Contact us today for details on the broad range of audit and evaluation types we can provide for you.
  • How do you monitor your inspectors work?

    YONGSHUN has a dynamic inspector and auditor training and audit program. This includes periodic retraining and testing, unannounced visits to factories where quality control inspections, or factory audits, are being conducted, random interviews with suppliers, and random audits of inspector reports as well as periodic efficiency audits. Our inspectors program has resulted in developing staff of inspectors that are among the best in the industry, and our competitors frequently try to recruit them away.
  • What kind of inspections do I need?

    The type of quality control inspection you need largely depends on the quality goals you are trying to achieve, the relative importance of quality as it relates to your market, and whether there are any current production issues that need to be resolved.

    We invite you to explore all the inspection types we provide by clicking here.  

    Or, you can contact us, and our staff can work with you to determine your exact requirements, and propose a custom solution to best meet your needs.

  • What does AQL mean?

    AQL is the acronym for Acceptable Quality Limit (or Level). This represents a statistical measurement of the maximum number and range of defects that is considered acceptable during a random sampling inspection of your goods. If the AQL is not achieved for a particular sampling of goods, you may accept shipment of the goods ‘as is’, demand a rework of the goods, renegotiate with you supplier, refuse the shipment, or choose another recourse based on your supplier agreement.  

    Defects found during a standard random inspection are sometimes classified into three levels: critical, major and minor. Critical defects are those that render the product unsafe or hazardous for the end user or that contravene mandatory regulations. Major defects can result in the product’s failure, reducing its marketability, usability or salability. Lastly, minor defects do not affect the product’s marketability or usability, but represent workmanship defects that make the product fall short of defined quality standards. Different companies maintain different interpretations of each defect type. Our staff can work with you to determine the AQL standard that meets your requirements according to the level of risk you are willing to assume. This becomes the primary reference during a pre-shipment inspection.

    It is important to note; the AQL inspection is only a report on the findings at the time of the inspection. YONGSHUN, like all 3rd party QC companies, does not have the authority to make a decision as to whether your goods can be shipped. That is a decision only you can make in consultation with your supplier after reviewing the inspection report.
