Inspection standards and methods for cotton rope storage baskets
Sampling inspection is the main form of textile inspection. A sampling test is when a certain number of samples are taken from a submitted batch and only the samples are tested to determine whether the batch is qualified. On the one hand, sampling is very important to carry out sampling inspection. On the other hand, a reasonable sampling scheme must be designed in advance so as to ensure the quality of the inspection. There are many sampling schemes, which are classified according to their characteristics as follows:
1, according to the quality characteristic value and the corresponding determination method
(1) Count sampling scheme: count sampling scheme uses the count method to test the quality of unit products in the sample, divides the product quality into qualified or unqualified products, and then counts the number of unqualified products in the sample, and compares the number of unqualified products with the judgment array to determine whether the batch products are qualified. The determination array is composed of the upper limit standard of the number of nonconforming items in the samples of the qualified batch and the lower limit standard of the number of nonconforming items in the samples of the unqualified batch. Textiles with multiple quality indexes are suitable for counting sampling scheme.
(2) Metrological sampling scheme: The metrological sampling scheme is to obtain the mean value or standard difference of samples by using the metrological method in sample inspection, and then determine whether a batch of products is qualified according to the judgment rules. The metrological sampling scheme has the advantages of small sample size, making full use of the quality information obtained from the inspection sample, but the use procedure is tedious and the calculation is complex, so it is more suitable for sampling inspection of single quality index in textile inspection.
2, according to the principle of the scheme
(1) Standard type: According to the principle of controlling the error size in sampling inspection, only the batch is qualified or not. The distinguishing feature is a definite solution that meets the quality requirements of both the producer and the user. It is suitable for situations where the product quality is unknown.
(2) Selection type: During the inspection, replace the unqualified products found in the samples with qualified ones, conduct 100% inspection on the rejected batches, and eliminate the unqualified products. Suitable for non-destructive testing.
(3) Adjusted sampling scheme: Adjusted sampling scheme is a complete system composed of normal, strict, relaxed, extra wide and other sampling schemes, which are connected with the transfer rules. When the product quality is reduced, the use of tightening program; If the quality of the product is stable and relatively high, the relaxed scheme is used. In general, the normal scheme is used. Which scheme to use is determined by the transition rules. This scheme is especially suitable for continuous batch sampling inspection.
(4) Continuous production: The continuous production of products on the conveyor belt, in the middle of the inspection, after passing the inspection of the product's average unqualified rate is controlled below a certain value (AQL). At the beginning, 100 percent inspection is carried out continuously on each product. If the result is that the number of nonconforming products is below a certain value, it is changed to sampling inspection at regular intervals. If the inspection results are found again, it will be changed to 100 percent inspection method.
3. Score according to the number of sample extraction
(1) One-time sampling scheme: The one-time sampling scheme only needs to extract 1 sample N from the total n of the inspected batch. According to the result of sample inspection, the qualified products of the batch can be determined. Primary sampling is also called single sampling or primary sampling. Its features are the most simple scheme, easy to use, widely used, but the sample is large, the workload of sampling inspection is also large.
(2) Secondary sampling scheme: In the secondary sampling scheme, the first sample n1 is taken from the total N of the inspected batch for inspection. If the quality of this batch of products can be judged based on this, the inspection will be terminated. Otherwise, take a second sample n2 and test it again, and judge whether this batch of products is qualified or not by combining the results of the two tests.
(3) Multiple sampling scheme: In the multiple sampling scheme, only after one or two samples (usually the same N, but not necessary) are extracted from the total n of the inspected batch, can the quality of the batch be qualified or not be concluded. It is the extension of the secondary sampling scheme, also known as multiple sampling. The characteristics of secondary and multiple sampling schemes are that the average inspection samples are smaller than that of primary sampling schemes, which can save inspection costs. However, the management is more complicated and requires special training of quality inspection personnel, so the management costs will increase and it is not suitable for textiles with low value.
(4) Sequential sampling scheme: only one unit of product is selected from the inspected batch for inspection each time, and then the judgment of qualified, unqualified or continued random inspection will be made until the judgment of qualified or unqualified batch can be made. The number of spot checks cannot be determined in advance and will only be known after a decision has been made.
4, according to the composition of the sample
(1) Batch by batch sampling inspection scheme: the products are divided into batches first, and then samples are extracted from a batch of products.
(2) Continuous sampling inspection scheme: the products do not need to form batches, but directly inspect the products at a certain inspection point on the continuous production line.
Pre-production Inspection (PPI)
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: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.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.
5. Check the conmponents of the products.
6. Perform the general tests.
(1) General function test.
(2) Dimension of packing or products.
(3) Gross weight or net weight.
(4) Carton drop test.
(5) Barcode number test.
8. Any other work that clients want us to do during the inspection.
1.Why do I need shipment inspections or factory audits?
In case of any Poor quality, incorrect shipments, unreal information from suppliers. Inspection is the most efficient way to protect buyer’s right.
Getting a rapid quotation should have a complete condition,such as gross weight size,quantity and where is the factory and where will it ship to."

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.
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.
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.

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.
