UNITS OF MEASURE
Units of measure: If present an “M” denotes that metric units of measure should be used, i.e. MPa for tensile strength, °C for temperature and kN/m for tear strength.
Grade number 1 = Basic Requirements 2 to 6 = Different requirements as detailed in table 6 of ASTM D2000 this specifies minimum basic requirements for tensile strength, elongation, heat aging, oil immersion and compression set by Classification (Type-class). Appropriate additional requirements apply to each classification, with the grade determining the allowable results.
The values in this guide have been extracted, with permission, from ASTM D2000-12 Standard Classification System for Rubber Products in Automotive Applications. Users should reference and confirm results with the originally published version of ASTM D2000-12. The complete standard may be obtained from ASTM, www.astm.org.
