Regardless of whether it is produced in batches or not, it is necessary to check each finished product individually to determine whether the quality meets the product standards. However, checking all products one by one will waste a lot of time and manpower. In fact, it may not even be possible to do so. Therefore, it is important to introduce the AQL level.
AQL is the abbreviation of "Acceptance Quality Limit", which is an international standard for confirming the quality of the inspected products. AQL is defined as the most intolerable quality level of the product. That is, the maximum number of defective units in the product, any product exceeding this number may cause the entire batch of products to be rejected.
1. How to set the appropriate AQL level between acceptance and rejection of a batch?
AQL is an international standard to ensure the quality of the products produced by the manufacturer. AQL varies from industry to industry. Various factors can cause AQL differences between products. Manufacturers should consider these factors when setting the appropriate AQL for their production.
First, when choosing the appropriate AQL for your product, manufacturers must determine your tolerance level. Once determined and understood, setting the AQL is convenient. The tolerance level of the product is usually set and determined in the following way: Classify the defect level of your production
2 Product defect type
AQL calculators and Acceptable Quality Limits are widely used in the QC industry to determine the sample size for inspection. Product defects are usually defined as the following types：
Severe defects
Production batches classified as having severe defects should be rejected directly regardless of the standard. Products in this category do not meet the basic standards required by the industry.
Major defects
Products considered to have major defects may not be accepted by consumers, not necessarily because they do not meet the quality requirements, but because of their condition when they were produced.
Minor defects
Products with slight deviations are defined as products with minor defects. Usually, consumers may not mind them.
Each batch of production may have 1~2 defects. That is, not every unit of a batch of production meets the quality standards set by the manufacturer. So it is necessary to classify the various defect levels of the product. It is helpful for buyers to set the appropriate AQL level for the production line.
