Some standard content:
CB/T 9102—2003
The standard atmosphere for humidity adjustment and testing in this standard is equivalent to IS) 13%:19734 Dynamic Group - Standard atmosphere for humidity adjustment test 3. [S13911 is adopted by GB5291986 standard fabric moisture permeability and test standard atmosphere, so this standard directly quotes GB652S. This standard tensile properties, adhesive content, strength, dry heat shrinkage (baking method), etc. are modified from the HIS FAC silk yarn test method (1995): Adhesion strength (H-extraction) test method is equivalent to ISO4647, 19822 standard rubber and fiber fabric static adhesion performance test - H-extraction, and [SO4647E is also used by GF/T2542--1991 rubber and fiber cord fabric adhesion test: T-extraction method, so this standard directly quotes GM/T292, and specifies the cutting depth, increases the amine formula and Vulcanization conditions: Ten heat shrinkage rate method (only according to ASMD49719 heat shrinkage test method for filament branch joints)
The main differences between this standard and the previous standard are as follows: the test light quantity in the ISFA (19> standard has been revised - the heat shrinkage group and the standard pre-tension in the A5TM::74-1S9 standard have been revised. This standard replaces G/T91021S88 "6 No Tape". In addition to adopting the above-mentioned standards, this revision also incorporates the relevant contents of CB/T102-108. Compared with G6/1V2-1928, this standard has the following major changes: the title name is used for acceptance, and the product specifications of the local organization such as the product must be used in Chapter 1). h) Added some meanings (see the first part):
c) Product classification part:

) Technical requirements part:
Change the physical index to the property index. And adjust some energy items. See Table 2 of 19k8 edition: Table 2 of this edition):
Adjustment: Adjust the net length of the single machine fracture elongation zone index value. The book separates the elasticity index value and adjusts the individual strength index value: The fracture force and fracture length are expressed by the variation coefficient, and the index value is adjusted accordingly. The thermal conductivity index value is improved. - External measurement increase currency [head effect mother's determination: the longer the system is, the more the 1988 version of the table 3: technical version of the table 3)) test method part,

A calculation formula for the variable conductivity coefficient was added (see 2. of this edition, downgraded): The glue engraving formula, the image part and the buried wire depth were strengthened. The other test methods were carried out according to C/2942 (2.71 of the 1599 edition and 6.4 of this edition). - Most of the corresponding changes in the adhesive test can be found in 2.1.2 of the 108R version. The inspection test in 5.5 of this edition has been added (compared with 5.7.5); - The dry heat shrinkage test has been added to the dry heat shrinkage instrument measurement method <see 6,%, 2)F
