Foreword

This standard is the international standard ISO 11235.1999 "Rubber compounding ingredients sulfenamide agent Test method of promoting" the degree of consistency Non-equivalent. This standard and ISO 11235.1999 main technical differences are as follows. --- Purity test method specified in this standard using only the mercapto benzothiazole solution reduction titration method in the A and B Method (ISO 11235.1999 4.1; 5.6 of this standard); Melting point test method specified in this standard --- using only capillary method (ISO 11235.1999 6.1; 5.2 of this standard); --- Sieve residue test methods specified in this standard by dry, wet sieving test method does not provide. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee rubber chemical additives Rubber and Technical Committee (SAC/TC35/SC12) Centralized.
