1. Scope and Application
This standard specifies methods for determining the hardness of vulcanized or thermoplastic rubbers. It is the primary reference document for quality control in rubber manufacturing in Japan. JIS K 6380 is a Japanese Industrial Standard
- Hardness Range: It covers a wide range of hardness, from very soft rubber to hard ebonite.
- Methods Described: The standard details three primary methods for measuring hardness based on the material's properties:
- IRHD Method (International Rubber Hardness Degrees): Suitable for standard laboratory testing.
- Durometer Method (Shore Hardness): Suitable for handheld, on-site, or factory floor testing.
- HARDOMETER Method: Specific to Japanese contexts for softer materials.
