Process inspection mainly includes the following aspects.

FII, also known as the "first-article inspection system," is a proven effective measure through long-term practical experience in identifying problems early and preventing batch-wi

The purpose of process inspection is to prevent a large number of defective products from flowing into the next process.

The inspection process comprises four stages.

Sample stability testing involves monitoring and analyzing the performance changes of a sample over a specific period to assess its resistance to external factors (such as temperat

Incoming inspection includes two types: first-piece (batch) sample inspection and batch inspection.

Before conducting sample testing, a series of preparatory steps are necessary.

Sample testing is the first and crucial step in chemical testing.

The importance of sample inspection in quality management extends beyond ensuring consistent product quality levels.

In quality management, sample inspection and full inspection are two distinct methods with significant differences in cost-effectiveness, time efficiency, and comprehensiveness.

In sample inspection, sample selection and inspection procedures are crucial for ensuring the accuracy and comprehensiveness of quality assessment.

Four key elements need to be verified during implementation.
