This standard H should be based on industrial standard [15K220-3:21: Test methods for preparations for use Part 3: Anti-aging full modification degree is non-equivalent.
The main differences between this standard and [3K62203:2101 are as follows. After experimental verification, the test method of this standard for pure seat determination adopts three methods of various machines, and the pure new type of new relative color working conditions are different from the industrial standard of this standard: JK 6220: 227°7, 4; 5,2 of this standard): In order to strictly control the heating temperature, the heating temperature control range formulated by the standard pyrotechnics and thermal equipment is consistent with the industry standard range of <115K602, 235: 1, 4.: The wood standard is full of 5, 3 steps, which is beneficial to the field of wood products. The technical graded wood grade specified in the standard 1SK22-2001 is the only 3.2 of this standard!
This standard 88231988 has the following differences:
About the test method: This version has added the following benefits:
Changed the main color of the product appearance "purple to the most forbidden color block\" to "purple car damage color flake" (1S version 1.11);
The technical standard of the product is open to the public (1Y version 1.1 and the total number of points of this version is reduced to 2), and this standard is issued by the China Petrochemical Industry Association. This standard is made into a national standard for rubber and rubber products Committee Chemical Additives Technical Committee, Guangdong Standard Organization: Nanjing Chemical Plant, Zhongka Chemical Industry Group: Qian Yingchun, the second standard was first issued in 1988. This is the first revision. 1 Scope

4 Samples
Excellent products
Sampling is done in batches. The manufacturer takes one batch of products according to the average value: the packaging of all products must be intact. When sampling, foreign debris should not fall into the product. Each batch shall be delivered to the total 10 slurry are drawn out by machine, and not less than 5 slurry for small batches: 1 stainless steel sampler is used to take slurry from the upper, middle and lower layers of the product in the bag, and the mixture is fully mixed. The long sample taken out from it is divided into two sterilized and dried plastic bottles or multi-mouth bottles, and the labels are marked with: production name, product name, batch number, sampling date, and name of the sampler. One copy is for inspection by the inspection department, and the price error is kept in reserve. 5 Test method Unless otherwise specified, the confirmation analysis method is used in the analysis. 5. [Appearance] Visual analysis is used for judgment. 5.2 Determination of purity Summary: Gas chromatography is used for determination with hydrogen flame as the detector, and calculation method is used. 5.2.1

Area process · Of course
The minimum selection area setting must be lower than 0.1 of the main peak. Weigh the antioxidant 4010NA sample, 1UR~0.158, and change it to 1Uml. Clean and dry the volumetric flask, use a flat ane to dissolve and dilute to the scale, and mix well. After the instrument is ready for operation, enter the detailed 1 call after the selection is completed, and then start GR/T 8828--2003
Measure the peak area of ​​equal distribution by a planner or workstation, and give the area distribution of antioxidant 4010NA, the value is expressed in %, or perform the following statistical calculations.
5.7.6 Result calculation:
The peak area of ​​antioxidant 4010NA is expressed in %, and the value is expressed in %. According to the following formula, A is the peak area of ​​antioxidant 4010NA. The unit is square millimeter (mm). The total area of ​​​​the single unit is square meter (m\).
