This specification covers the minimum physical and chemical requirements for five technical grades of raw natural rubber. Materials are classified into grades according to retained dirt content, ash content, volatile matter content, nitrogen content, initial plasticity, plasticity retention index, color index, and Mooney viscosity. Skim rubber is not permitted in any grade.
