Quality Inspections can be made by two different models: 1- Sample Quality Inspection: Quality inspection with randomly chosen Sample Quantities 2- Full Inspection: Quality inspection with the full quantity
1-Sample Quality Inspection
Sample Quality Inspection is a random inspection method. Our inspector selects from the whole quantity of your order a sampling lot, a small number of products that will be controlled visually and functionally. The result of that small quantity of finished products should represent the overall quality of your whole order according to the international AQL quality control method MIL-STD-105E / ISO 2859-1. According to the results of the report, you’ll have an estimation of the overall quality of your goods. It can be performed either at the beginning, the middle, or the end of production. Sample Quality Inspection, is the most used and common quality control method right now, for the last decade.
What is AQL? AQL means “Acceptable Quality Limit” or “Acceptance Quality Level”. AQL is a recognized international method for random sampling quality inspection, that comes with predefined sampling quantities to inspect as well as predefined levels of acceptance for maximum defects quantity.
Depending on how many pieces is your order total quantity, we look at the AQL Table-1 and first define how many pieces we will need to check, which is the inspection sampling quantity. Then for each sampling quantity, the AQL table will enable us to know what is the maximum acceptance during inspection for critical, major, and minor defects with Table-2. After completing the inspection, If the quantity of defect is inferior to the AQL maximum limit, then basically it means your order is quality compliant. On the other hand, if after completion of the inspection the quantity of defects is superior to the AQL maximum limit, then it means there are quality issues that might prevent you from accepting the shipping of the goods.
2-Full Inspection
Full inspection, also called full quality inspection, means the control of each and every piece of your order at your supplier factory before shipment. It is mostly performed at the end of the production.
While being more expensive than a Sample Quality Inspection, it is the safest product quality inspection services. You make sure, by inspector check products one by one, that your whole production is flawless.
100% inspection allows you to make sure there is no quality issue whatsoever in your production. The defect rate in the shipment is very close to zero after this 100% check.
