ASTM D 6576 (Formerly Mil R 6130)
Description:
Standard Specification for Flexible Cellular Rubber Chemically Blown
Types
Type I - Open cell (sponge rubber)
Type II - Closed cell (expanded rubber)
Grades - Both types are divided into three grades designated by the letters A, B, & C added to the Roman numeral prefix
Grade A - Oil- and flame-resistant
Grade B - No requirements for oil, flame resistance, or low temperature
Grade C - Low-temperature resistant (oil and flame resistance not required)
Please view the data sheet for more information and important exceptions.
Conditions - Each type and grade has been divided into six different conditions. Each condition is based on a specific range of firmness as expressed by compression deflection as follows:
Super soft: Compression deflection range of >0 to 13.8 kPa (>0 to 2 psi)
Soft: Compression deflection range of >13.8 to 34.5 kPa (>2 to 5 psi)
Soft-medium: Compression deflection range of >34.5 to 62.1 kPa (>5 to 9 psi)
Medium: Compression deflection range of >62.1 to 89.6 kPa (>9 to 13 psi)
Medium-firm: Compression deflection range of >89.6 to 117.2 kPa (>13 to 17 psi)
Firm: Compression deflection range of >117.2 to 172.4 kPa (>17 to 25 psi)
Scope: This specification establishes requirements for chemically blown cellular rubber
