sampling plan for inspection
What is a sample inspection plan?
The sample inspection plan can be something like starting out with 100% inspection and then changing over to sampling inspection after a certain number of consecutive conforming products. If a nonconformity is found, the mode of inspection returns to 100% inspection.
What is a sampling plan?
A sampling plan allows an auditor or a researcher to study a group (e.g. a batch of products, a segment of the population) by observing only a part of that group, and to reach conclusions with a pre-defined level of certainty. In this article I cover these cases in-depth (hit the links below to skip to the relevant section):
What is sampling inspection based on operating characteristics?
Sampling inspection based on operating characteristics is an inspection plan that defines the producer protection and guarantee for purchasers, and also meets the demands of both the producer and purchasers.
What is sampling inspection with adjustment?
Sampling inspection with adjustment can be indexed by AQL or LQ, or be conducted as a skip-lot inspection plan. The sampling procedure for inspection with adjustment is defined in ISO 2859-1, ISO 2859-2, and ISO 2859-3. In a rectifying inspection, a lot that has been rejected in a sampling inspection is subjected to a 100% inspection.

Statistical Sampling Plans
How can you make the link between this plan and your risk as the buyer (of accepting a batch that is worse than what you are willing to accept)?Let’s say you find 3% of the samples you picked are defective. You are left negotiating with the factory, with no previously-agreed rule to decide if they should take action (e.g. sort out the whol
Situation 3: You Want to Implement An ‘Acceptance on Zero’ Sampling Plan
Some importers, who are sensitive to legal litigation by their customers or who have high-quality standards, accept batches only if no defective unit is found. This is common in industries such as automotive or pharmaceutical. In some cases, the producer itself adopts this type of approach for its outgoing quality control. One big advantage is the
A Few Other Types of Sampling Plans
I can’t cover all types of sampling plans used for quality control purposes. But here are three others. 1. I only covered plans “by attributes”, which classify the samples as either “non-defective” or “defective”. If a plan is “by variables”, it allows for a finer evaluation. For example, the length of the product is measured, and the exact finding
