AQL Levels

How do SGRInspecion inspectors perform Quality Standard?
We will offer professional inspection services for your goods according to globally recognized international quality standard: ISO 2859,These tables are of the US standard with equivalents in all national and international standardization organizations (ANSI/ASQC Z1.4, ISO 2859-1, NF06-022, BS 6001, DIN 40080, GB/T 2828.1-2003).

What quality standards do we use?
We randomly select a sampling size quantity (based on the AQL tables) to be inspected. We inspect the sampling size and classify the defects into critical, major and minor defects.
Critical Defect: A defect that fails to meet mandatory regulations and/or affects the safety of the consumer when using the product.

Major Defect: A defect that is likely to result in product failure, reduction the usability of the product and obvious appearance defect affecting the salability of the product.

Minor Defect: A defect that is not likely to reduce the usability of the product, but is likely to reduce the salability or a discrepancy from the defined quality standard.

1.According to the number of defects found for each type and according to the number of defects allowed (figures given by the AQL tables), we will advise you to accept or to reject your shipment.

Then it is up to you to make your own decision based on the information and recommendations we have provided to you.

2.We check the sample goods according to AQL ( Acceptable Quality Levels ) and your special requirement such as fixed sample check .

Statistical Sampling is widely used to decide whether or not to accept or reject a production lot without checking every single items of the lot. It is equally applicable to incoming inspections of shipments of raw materials or partially finished products, products at various stages of manufacture, and finished products as well as outgoing shipments.

3.Generally we would check goods on its quantity , workmanship , product description , style, size sand color , measurement data , packaging and shipping mark .

4.After inspection , we will release you an inspection report attached with digital photos showing you actual findings and informing you overall conclusion for your reference to make decision .

How to use the AQL Tables?
The AQL tables will help to determine the sampling size we will need to inspect according to your ordered quantity and your level of severity (I, II or III). The standard level commonly used is the level II for a standard inspection.

Indeed, for a standard order, the standard level II from the AQL gives the minimum sampling size we should check per reference if we do not want to take additional risks. If we inspect a general level II sampling size on a multiple references orders, then the sampling size is diluted and divided by the number of references, increasing the risks as the sampling size must be representative enough.

Please check here if you want to see more explanation about the AQL tables and the AQL tables itself.

SGRInspection uses the Acceptance Quality Limit standard during product inspections, unless an other standard is requested by the client. The standard definition of Acceptance Quality Limit (AQL) is "the maximum defective percent (or the maximum number of defects per hundred units) that, for purpose of sampling inspection, can be considered satisfactory as a process average".

In order to find the necessary sampling size to be inspected, we look at the first chart and find on the left side the range of items being produced in total. You have the choice of levels I, II and III, with Level III being the most stringent testing and level I being the least. Level II is the standard and is most often used. For example, Example One: For an order of a batch of clothing of 6,000 pieces, at level II you have the letter L, which in the second table says to inspect 200 items.

On the top of the second chart are the defect levels, ranging from 0 to 6.5. You can choose which level to apply for your type of defect: critical, major and minor. Usually most importers will choose standard defect levels which are 0/2.5/4 but one can choose 1/1/1 if he wishes or 0/1.5/2.5 like in the automotive industry. Using the standard 0/2.5/4 defect levels and a sample size of 200, we see that if you have more than 0 critical defects, 10 major defects or 14 minor defects, you should reject your shipment. Of course the decision about what to do after your received the inspection results belongs to you. Most importers will wish to discuss all inspection findings with their vendor/manufacturer in order to improve whatever possible. In case the inspection results are very close to AQL limits, it is important that you double check if the level of found defects is acceptable to you or not.
