CPARCEL Quality Control AQL Calculator

The need for consistent product quality and a reliable method for identifying these standards is essential for a successful business model. Quality control plays a crucial role as it helps reduce risk, use resources efficiently and ultimately reduce production costs. It enables effective management of supply chains and strengthens a company's negotiating position, while improving brand protection through a strategically planned approach.

The application of AQL (Acceptable Quality Limit) sampling, a proven method for quality assurance of production orders, helps to minimize risks before official product release. The AQL classification divides products into three levels based on the type and extent of defects: critical, major, and minor defects. To efficiently classify a product and determine its tier, it is recommended to use an AQL calculator instead of traditional spreadsheets. This tool enables a faster determination of the sample size and the accurate recording of the error rate.

What is an AQL inspection?

AQL inspection is a key building block in setting product control standards. According to ISO 2859-1, it defines the minimum level of acceptable standards for consumer products during multiple inspection phases. AQLs are used to check that a product conforms to customer specifications.

AQLs can be defined for critical, major, and minor defects as a percentage or absolute number. Critical errors that have 0% tolerance can endanger users, violate regulations, or cause product failure. Major defects, allowable up to 2,5%, render the product unacceptable to the end user, while minor defects, tolerated up to 4%, fail specifications in a way that is still tolerated by most buyers.
