Acceptance sampling is a statistical quality control procedure used to determine if a production lot or batch of goods meets the required standards.
It involves taking a sample from a lot or batch and then making a decision about the entire lot or batch based on the sample results.
How to calculate
-
Establish a sampling plan: The sampling plan should include the sample size, acceptance criteria, and the acceptable quality level.
-
Collect sample: A sample is taken from the lot or batch and is inspected or tested.
-
Evaluate results: The sample is evaluated to determine if it meets the specified acceptance criteria.
-
Accept or reject lot: If the sample meets the criteria, the entire lot is accepted. If it fails, the lot is rejected.
-
Record results: The results of the acceptance sampling procedure should be documented and kept on file.
Examples
- Quality inspection of incoming parts in a manufacturing process.
- Testing of outgoing products to ensure they meet quality standards.
- Medical testing to determine the efficacy of a new drug.
- Sampling of food products to ensure safety.
- Sampling of raw materials to ensure quality.
- Sampling of agricultural and industrial products to identify potential contaminants or impurities.
