Description of ASTM-D6814 2008

ASTM D6814 - 02(2008)

Standard Test Method for Determination of Percent Devulcanization of Crumb Rubber Based on Crosslink Density

Active Standard ASTM D6814 | Developed by Subcommittee: D11.20

Book of Standards Volume: 09.01




ASTM D6814

Significance and Use

It is important for rubber compounders to know the extent of devulcanization a rubber might have undergone during recycling. It allows the compounder to determine if more curing agents are needed during mixing of devulcanized rubber when used either as partial replacement or stand alone.

1. Scope

1.1 This test method covers the procedure for determining percent devulcanization from crosslink density measurements of devulcanized rubber and control crumb rubber in the laboratory. Percent devulcanization is a quantitative determination.

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.


2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
