Understanding ASTM D 2000 Callouts

ASTM International (formerly known as American Society for Testing and Materials) developed the ASTM D 2000 Standard to streamline the specification of synthetic rubber via standardized line call-outs. This allows OEMs to use compounds from different manufacturers while ensuring consistent material quality and performance.

How Does ASTM D 2000 Work?

The ASTM D 2000 Standard breaks down the essential properties of all rubber products into a set of standardized material designations. These designations indicate material properties and functions (including resistance to heat), and classes (such as resistance to swelling). The tables below show the meanings of individual ASTM designations.
