Organization: ASTM International
Publication Date: 10 November 1997
Status: inactive
Page Count: 2
ICS Code (Rubber): 83.060
scope:

1.1 This test method describes the determination of assay of benzothiazyl disulfide (MBTS). It is based on a titration of free iodine liberated upon reduction of MBTS, with potassium iodide (KI) in acid medium.

1.2 The assay is determined as mass percent.

1.3 Free 2-mercaptobenzothiazole (MBT) content is not determined.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 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.
