Wood standard products under chemical industry standard HG2:
Acid red is based on the period of retrograde tin.
This standard is different from IIC 25-1*82 in that the new name is used based on the original product naming of 381 aggregate. Various items are tested and indicators are determined according to the methods specified in the national standards: the dye pressure content index of small water in Beijing standard is increased by 1.0% to a maximum of 0.5% - the spectral chart and spectral diagram of the original standard are cancelled. This standard will be implemented from the month when it replaces IIG/T 2990-1582. This standard was proposed by the Technical Supervision Bureau of the former Ministry of Chemical Industry of the People's Republic of China: This standard sets out the technical requirements for standardization of all-purpose dyes. This standard was drafted by the National Chemical Research Institute of China, and was first issued as a national standard in 175, and was revised for the first time in 1882. In 1500, it was recommended as an industry organization.

HG239-1382
This standard specifies the requirements, sampling, test methods, inspection principles and marking, labeling, packaging, transportation and storage requirements of Acid Red 4B.
This standard is used to determine the abrasive part of Acid Red 4B obtained by coupling with 4-hydroxy-1-hydroxyphenol in a reactive medium. Acid red 4B is used for dyeing silk and non-pharmaceutical products. Its structure is:
molecular formula: rH.NSNa
molecular weight: 502.42 (according to the International Standard of Relative Atomic Mass in 1999) 2 Referenced standards
The texts contained in the following European standards shall become the detailed provisions of this standard through reference in this standard. When this standard is published, the versions shown are the effective versions. All standards will be revised as of the date of publication: All parties using the following standards should explore the possibility of using the latest versions of the following standards. $B/T2374-4 General provisions for dyeing by dyes GB/T 2378-8.

And the user to receive the same production plant with the same batch number of output as one trillion. Take 10 packages of each batch of products, and the sampling of small batches of products shall not be less than 3 packages. When sampling, use a deep sampling method to sample from the upper, middle and lower parts of the package, and be careful not to let foreign impurities fall into the product. The total amount of the sample shall not be less than 2B. After the sampled products are fully tested, they are divided into two clean bottles and labeled with the following: manufacturer name, product name, license number, sample date, location and name of the sampler. One bottle is for inspection, and the bottle is kept in the right wax case for future reference. 5 Test method
