6 Inspection rules
6.1 Inspection types
6.1.1 Finished product inspection is divided into exit-factory inspection and type inspection. The timing of the type inspection is based on the actual situation of the manufacturer or the provisions of the contract agreement. It is generally carried out when the production is switched to other products, the production is resumed after the suspension, or the raw materials or processes have major changes.
6.1.2 The exit-factory inspection items shall be in accordance with the regulations in Chapter 4, except 4.11. The exit-factory inspection rules for finished products are in accordance with FZ/T 80004.
6.1.3 The type inspection items shall be in accordance with Chapter 4.
6.2 Appearance quality grade and defect classification rules
6.2.1 Classification of appearance quality
The classification of finished product quality is based on the existence and severity of defects. The single product in the chosen sample is classified according to the number of defects and their severity, and the batch grade is classified according to the quantity of the quality grade of single products in the chosen sample.
6.2.2 Classification of appearance defects
A single product does not meet the technical requirements specified in this document, that is a defect.
Defects are divided into 3 categories according to the degree to which the product does 6.3.2 The number of samples used for physical and chemical performance inspection shall be determined according to the needs of the test, generally not less than 6 pieces (or sets).
6.4 Judgment rules
6.4.1 Single piece (sample) determination
Superior product: critical defects=0, major defects=0, minor defects???4; First-class product: critical defects=0, major defects=0, minor defects???7 or critical defects=0, major defects???1, minor defects???3;
Qualified product: critical defects=0, major defects=0, minor defects???8 or critical defects=0, major defects???1, minor defects???6.
6.4.2 Batch grade determination
Superior product batch: the proportion of superior products in the appearance inspection samples is ???90%, the total proportion of first-class products and qualified products is ???10%, and no unqualified products are included. All physical and chemical performance test results meet the index requirements of superior products. First-class product batch: the total proportion of first-class and above products in the appearance inspection samples is ???90%, the proportion of qualified products is ???10%, and no unqualified products are included. All physical and chemical performance test results meet the index requirements of the first-class products.
Qualified product batch: the proportion of qualified and above products in the appearance inspection samples is ???90%, the proportion of unqualified products is ???10%, and there are no unqualified products with critical defects. All physical and chemical performance test results meet the index requirements of qualified products. When the judgment of appearance sewing quality is inconsistent with the judgment of physical and chemical properties, the products shall be judged as a lower grade. 6.4.3 Eligibility determination
In the random inspection, if the judgment number of a batch conforms to the corresponding grade regulations in 6.4.2, then it is judged as a qualified batch.
