Quality St和ards

We use the internationally recognized Acceptable Quality Limit (AQL) st和ard for all product inspections. Clients can set their Acceptable Quality Tolerance level for each inspection 和 bet366沙巴体育 will provide results as within or beyond AQL.

Acceptable Quality Limit (AQL)

In performing sampling inspection, bet366沙巴体育 inspectors exclusively apply the ISO 2859 st和ard 和 the tables provided by it. 这个文档, published by the International Organization for St和ardization (ISO), is an international st和ard with equivalents in all national regulations (ANSI/ASQC Z1.4, NF06-022, BS 6001, DIN 40080).

AQL (Acceptable Quality Limit) Sampling is a method widely used to define a production order sample to find whether or not the entire product order has met the client's specifications. Based on the sampling data, the customer can make an informed decision to accept or reject the lot.

Your inspection report will clearly state whether your production has passed or failed your selected Acceptable Quality Tolerance level.

How do I determine the right sample size 和 acceptance number?

Our trained account managers will be available to ensure you choose the inspection level 和 AQL values that best suit your needs.

You can already simulate using our sampling calculation tool below: enter your shipment lot quantity, 和 select sampling levels 和 AQL to see the impact on inspected quantities 和 accepted defects.

Example: for a hypothetical inspection of a production with 4,000个单位, the client selected level II normal inspection 和 AQL of 2.5.

In Table A below, the intersection of the respective Lot Size 和 General Inspection Level indicates sample size code letter L. Then, referring to Table B, we locate row L, which indicates the required sample size of 200. To comply with AQL 2.5, no more than 10 单位 from that sample size may fail inspection.
