How to determine the correct quantity and acceptable fault levels when inspecting a product. August 5, 2013 - by Aidan Conaty To determine the AQL level of a product you need to use the measure table that is recommended by ISO 2859, NF06-022, DIN 40080, BS 6001, ANSI/ASQC Z1.4. Use the letter identified in the Sample Size Chart to

It is the ‘best case failure rate’, assuming you barely pass your inspection. Based on the table, for an AQL of 2.5%, the plan would allow 5% (10 out of 200) failures for inspection level II. Clearly, 2.5% is not the worst case when the plan allows 10 out of 200 to fail. 其抽样方案见表: 正常检查一次抽样方案(AQL-2.5) AQL 是----ACCEPT QUALITY LEVEL 的简称， 是一个国际标准， 1 ） AC=Acceptable number =使用箭头下面的第一个数值 =使用箭头上面的第一数值 抽样数量是以一般检验 II 级检验水平来进行的。 Normally standard garments factory work to an AQL 2.5 for major defects and AQL 4.0 for minor.

Unless otherwise specified, level II shall be used. Level I may be used when less discrimination is needed or level III when greater discrimination is required. Four additional special levels, S-1, S-2, S-3 and S-4 are also given in Table 1 and may be used where relatively small sample sizes are necessary and larger sampling risks can be tolerated.

We are following that AQL table in garment quality inspection. Let's look at the AQL chart (shown below). In the table, there is a column named AQL 2.5 (red boxed). So when you are doing shipment inspection at 2.5 AQL level, you need to know your shipment lot size, sample size and follow the 2.5 AQL column.

When using General Inspection Level II, the factory learns from the second chart that this quantity order equates to "M". The factory then goes to the first chart and sees that for "M" they should inspect 315 garments. If they want a 2.5 AQL they can have 14 defective units or less from the 315 that they inspect. If they have 15 defective units Also, the sampling of the shipment lot is done as - single sampling and double sampling. Further AQL level is categorized as AQL 0.1, AQL 2.5, AQL 4, AQL 6.5 etc. When you prepare AQL chart with all these combinations, you will get various AQL charts. Here we will be talking about AQL chart used for shipment inspection in the apparel industry. If the buyer only mentions AQL 2.5, it means that the buyer accepts all kind of defects: critical, major or minor, to be present in the manufactured goods at a level of 2.5% of the total order quantity. Knowing that a critical defect is dangerous for the user, it is quite risky for the buyer to include in the 2.5% such defect type. We are following that AQL table in garment quality inspection. Let's look at the AQL chart (shown below). In the table, there is a column named AQL 2.5 (red boxed). So when you are doing shipment inspection at 2.5 AQL level, you need to know your shipment lot size, sample size and follow the 2.5 AQL column.
