ASTM D 1056 2A1
Description:
Standard Specification for Flexible Cellular Materials - Sponge or Expanded Rubber
Classification
Type 1 Open Cell Rubber
Type 2 Closed Cell rubber
Class A: Resistance to petroleum base oils is not required (Formerly RE)
Class B: Specific requirements for oil resistance with low mass change (Excellent resistance) (Formerly SBE)
Class C: Specific requirements for oil resistance with medium mass change (Medium resistance) (Formerly SCE)
Class D: Extreme temperature resistance (No oil resistance required)
Grades: Firmness as measured by compression deflection (25% compression, measure load – psi [kPa])
Grade 0: 0 - 2 psi; 0 - 13.8 kPa
Grade 1: 2 - 5 psi; 13.8 - 34.5 kPa
Grade 2: 5 - 9 psi; 34.5 - 62.1 kPa
Grade 3: 9 - 13 psi; 62.1 - 89.6 kPa
Grade 4: 13 - 17 psi; 89.6 - 117.2 kPa
Grade 5: 17 - 25 psi; 117.2 -172.4 kPa
Please view the data sheet for more information and important exceptions.
Scope: This specification covers flexible cellular rubber products known as sponge rubber and expanded rubber, but does not apply to latex foam rubber or ebonite cellular rubber. The base material for an open/closed cellular product may be made of synthetic, natural, reclaimed rubber, or a mixture, and may contain other polymers or chemicals, or both, which may be modified by organic or inorganic additives.
