Shake the solution thoroughly, and let it stand for 10m to make the direct-fast red 4 ugly S and color thorn Y form a complex salt solution. Filter it through three-year-old filter with double-can paper in a colorimetric medium. Compare the color of the selected solution. The chromaticity of the filtrate should be close to 4.6 degrees of color.

5.1 Inspection classification
3.1 and 3.2 of the technical requirements of this standard are general inspection items. All items in the technical requirements of this standard are type inspection items. If there are 6.6.1. Plastic inspection is carried out when one of the specified circumstances occurs. During normal production, it is carried out once a day. 52. Sampling method
Select 10% of the sample from each batch (the uniform product mixed once is a batch); before sampling, the dust on the box cover should be cleaned to prevent foreign impurities from falling into the product. Samples are taken from the upper, middle and lower parts of the barrel with a sampler. After the sample is fully mixed, more than 300 grams are taken out and placed in two clean and dry bottles, which are sealed with paraffin and labeled with the manufacturer's name, product name, batch number and sampling date. One bottle is for inspection and the other is kept for reference. 5.3. Factory inspection
The color fixation should be inspected by the quality inspection department of the production department. The manufacturer shall ensure that all products meet the technical requirements of this standard. Each batch of products leaving the factory shall be accompanied by a quality certificate in a certain format. 4. User acceptance
The user has the right to accept the products according to the provisions of this standard. When the supplier and the buyer have objections to the product quality, the two parties shall negotiate.
S Double-entry
If the inspection result shows that one index does not meet the requirements of this standard, the sample from the packaging with twice the quantity shall be re-tested. If there is one item that does not meet the requirements of this standard, the whole batch of products shall be unqualified. 56. Arbitration
When the supplier and the buyer have objections to the product quality, the arbitration agency may be selected by both parties, and the calibration shall be carried out according to the method specified in this standard.
6 Marking, packaging, transportation and storage
61 The product packaging should have clear markings to indicate the product name, standard room, trademark, batch number, net weight, production period and production name.
