What is BS EN ISO 2859-10:2012?

The BS EN ISO 2859-10:2012 standard is an internationally recognized quality control procedure used in various industries to determine the acceptability of products, components, or materials by inspecting a sample. It provides guidelines for inspection plans, sampling schemes, and decision rules based on statistical methods.

Sampling Procedures

One of the key aspects of BS EN ISO 2859-10:2012 is the sampling procedure. This method involves selecting a representative sample from a lot or batch of products for inspection purposes. The standard defines multiple sampling levels, each with its own acceptable quality limits.

The sampling procedure consists of two main types: single sampling and double sampling. Single sampling involves evaluating the entire sample size at once, while double sampling allows for an initial assessment followed by a second evaluation if necessary.

Acceptance and Rejection Criteria

BS EN ISO 2859-10:2012 provides clear acceptance and rejection criteria to determine whether a lot or batch should be accepted or rejected based on the observed number of nonconforming units within the sample. These criteria rely on statistical calculations using measures such as Acceptable Quality Level (AQL), Limiting Quality Level (LQL), and Lot Tolerance Percentage Defective (LTPD).

The standard takes into account the desired level of consumer protection and the producer's risk. A higher AQL allows for a higher acceptance rate but increases the likelihood of accepting defective products. On the other hand, a lower AQL reduces the consumer's risk but may increase the cost of production due to a higher rejection rate.

Benefits and Application

BS EN ISO 2859-10:2012 offers several benefits to organizations. First and foremost, it ensures consistent quality control practices throughout the production process, reducing the likelihood of delivering faulty products to customers. It also allows for effective communication between suppliers and customers, as both parties can agree upon acceptable quality levels.

This standard is widely applied in manufacturing industries such as automotive, electronics, pharmaceuticals, and textiles. It helps companies optimize their inspection efforts, improve product reliability, and minimize costs associated with rework, returns, and customer complaints.
