Inspection Sampling Process

Identify the number of products to be inspected according to the AQL table (Single Sampling Plan for normal inspection), then follow below process to do the sampling:

1. Select the right quantity of cartons

At least the square root of the total number of cartons, or otherwise defined by client, in the shipment are randomly selected and opened. The inner content is checked for correct quantity and assortment. The samples are selected proportionally from the opened cartons. If the sum of opened cartons cannot give the sufficient number of sample size, cartons should be opened until the quantity is met.

2. Randomly select the cartons from the pallets

Select the cartons randomly, for example, from the front and back, top and down, right, let and inside of the pallet, not just from the same position of the pallet. If the goods are not 100% packed, also need to select the samples from the unpacked products according to the ratio of packed and unpacked pieces.

For example, if there are 200pcs among 5000 to be inspected, and there are just 4000pcs packed into cartons, and 1000pcs ready to be packed, have to select 160 pieces from cartons and 40 unpacked pieces.

3. Randomly select the products from selected cartons

During the selection of products from cartons, need randomly pick up the pieces, for example, from each lay or each poly bag of product, to represent the real product quality situation as maximum as possible.

Defects Classification Criteria

Defects detected during inspection are classified within 3 categories -"Critical", " Major ", " Minor "and the normal definitions are:

Critical: Defects which could result in hazardous or unsafe conditions for individuals using or maintaining the product as well as defects contravening legal regulations.

Major: Functional defects reducing the usability or solidity of the product as well as obvious visual defects reducing the sales value of the product.

Minor: Defects that are unlikely to reduce the use of the product, but nevertheless may influence the sale.

For random inspection, the following rules are applied: If the same sample has several defects, only the most serious defect is counted. In the case of critical defects, the entire shipment must be rejected as a matter of principle and clients consulted for a decision.
