(Japanese Industrial Standard) defines the classification of rubber materials used for industrial rubber packings, gaskets, and similar products. It provides a systematic way to identify rubber based on its physical properties—such as hardness, tensile strength, and oil resistance—rather than just its polymer type.
Full PDF versions are generally paid documents available through the Japanese Standards Association (JSA) or distributors like Intertek Inform .
The standard uses a coded system to define the performance characteristics of a rubber material: Type (Heat Resistance):
