ASTM D2000 callout decoder
Paste a rubber material line callout (e.g. M2BG714 B14 EO14 EO34) and read what each field requires.
How a D2000 line reads
| M | Metric (SI) units. Without M, older inch-pound tables apply |
|---|---|
| Grade (digit) | 1 = basic requirements only; higher grades add suffix requirements |
| Type (letter) | Heat-aging test temperature |
| Class (letter) | Max volume swell in IRM 903 oil |
| Hardness (digit) | Shore A durometer ×10, ±5 |
| Tensile (2 digits) | Minimum tensile strength, MPa |
| Suffixes | Extra tests (letter = test, digits = method and temperature) |
Summary for orientation. The current ASTM D2000 edition governs: confirm limits and suffix test temperatures in the standard.
