ASTM D5460 - 02(2012)
Standard Test Method for Rubber Compounding Materials—Water in Rubber Additives
Significance and Use
4.1 This test method is designed to determine the water content of various rubber accelerators. Since 2-mercaptobenzothiazole sulfenamide is hydrolytically unstable, the residual water content is an important characteristic.
1.1 This test method covers a procedure for the determination of water in 2-mercaptobenzothiazole sulfenamide accelerators by a Karl Fischer coulometric titration.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
