5.1.3 Type inspection items are to be in accordance with Chapter 3.
5.2 Appearance quality level and defect division rules
5.2.1 Appearance quality classification
The quality grade of the finished product is based on the existence and severity of defects. The number of defects in a single product in a sample
The degree of severity is divided into grades, and the batch grade is divided by the number of products of a single product in the sample.
5.2.2 Classification of appearance quality defects
A single product that does not meet the requirements specified in this standard constitutes a defect. According to the product does not meet the standard requirements and the product performance, appearance
