5.2 Determination of specification

The specifications and dimensions of the main parts are determined according to the method, which is described in GB/T 31907. The allowable deviation of specifications and dimensions shall be in accordance with Table 6.

5.4 Determination of down quality

5.4.1 Take out all the down of the whole sample. Mix it evenly before test.

5.4.2 Down quality is measured according to the method, which is described in GB/T 10288-2016, of which:

preparation is uniformly performed according to the steps of completing the composition analysis test.

b) Turbidity is determined, according to the method described in Method A in c) The bulkiness is measured, according to the method described in Appendix C.

5.5 Determination of appearance

5.5.2 When assessing the degree of color difference, the yarn direction of the assessed part shall be the same. The incident light is at an angle of about 45° with the surface of the fabric.

When appropriate, use a steel tape or ruler for measurement. […]

5.6 Determination of physical and chemical properties

5.6.2 Alkylphenol (AP) and alkylphenol polyoxyethylene ether (APnEO) are determined, according to the liquid chromatography-mass spectrometry (LC- MS), which is described in 6.2 of GB/T 23322-2018. Take a representative specimen and mix well. Weigh 0.5 g of specimen, from the mixed sample, accurate to 0.01 g. Place it in a 250 mL conical flask with stopper. Add 80 mL of methanol. Ultrasonically extract it for (60 ± 5) min at (70 ± 2) °C. 5.6.4 The color fastness to light is determined, according to the method described in GB/T 8427-2019, in which the exposure is carried out according to Method 3, meanwhile the exposure is carried out to the first stage. 5.6. […]

6.1 Classification of inspections

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 conditions of the manufacturer OR the contractual agreement. It is generally carried out, when the production is transferred, the production is resumed after the production suspension, the raw materials or processes have major changes.

6.1.2 The exit-factory inspection items shall be in accordance with the provisions of Chapter 4, except for 4.3.3 and 4.11. The exit-factory inspection rules for finished products are in accordance with the requirements of FZ/T

6.1.3 Type inspection items are in accordance with the requirements of Chapter 4.

6.2 Appearance quality grade and defect classification rules

6.2.1 Appearance quality grading

The quality grading of the finished product is based on the existence and severity of defects. The single product in the sample taken is graded, by the number of defects and its severity. The batch grade is classified by the grade of single products in the sample taken.

6.2.2 Classification of appearance defects

A single product that does not meet the requirements specified in this document constitutes a defect. According to the product's non-compliance with the requirements of this document as well as the degree of influence on product performance and appearance, defects are divided into three categories. […]

6.3 Sampling requirements

The sampling quantity is according to the product batch size:

- For 500 pieces (sets) and below: Randomly inspect 10 pieces (sets);

- From 500 pieces (sets) or more to 1000 pieces (sets) [including 1000 pieces (sets)]: Randomly inspect 20 pieces (sets);

- For more than 1000 pieces (sets): Randomly inspect 30 pieces (sets);

- For the sampling for physical and chemical performance inspection, it is generally not less than 4 pieces (sets), according to the needs of the test.

6.4 Judgment rules

6.4.2 Judgement of batch grade

If one or more of the down quality and physical and chemical properties are unqualified, the batch will be judged to be unqualified. Superior product batch: The number of superior products in the appearance inspection sample is greater than or equal to 90%; the number of first-grade and qualified products is less than or equal to 10%; meanwhile it does not contain nonconformance products. The down quality is qualified; all physical and chemical performance tests reach the requirements of superior products. […]
