Quality Standards

We use the internationally recognized Acceptable Quality Limit (AQL) standard for all product inspections. For each inspection, this allows the client to set their acceptable quality tolerance levels.

Acceptable Quality Limit (AQL)

The Acceptable Quality Limit, commonly referred to as AQL, is a method widely used to measure a production order sample to find whether or not the entire product order has met the client's specifications. The customer then has the data to make an informed decision to accept or reject the lot.

QC-I Inspectors exclusively use ISO 2859 tables to measure AQL. These tables are a United States standard with equivalents in all national and international standardization organizations (ANSI/ASQC Z1.4, NF06-022, BS 6001, DIN 40080).

Your inspection report will clearly state if your production has passed or failed your selected AQL.

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

Our trained account managers will be available to ensure you choose the inspection and AQL that is correct for your needs.

For a sample:    inspection of a production with 3800 pcs, with an General level II,AQL Cri0/Maj 2.5/Min 4.0 , Table A indicates a general inspection level of "L".

 Referring to Table B row L. Sample size is 200,  Max.Allowed for 2.5/4.0 is 10/14.

Remarks:

*critical defects (totally unacceptable: a user might get harmed, or regulations are not respected). 
* major defects (these products would usually not be considered acceptable by the end user). 
* minor defects (there is some departure from specifications, but most users would not mind it).
