: Used as flexible joints or weather-resistant covers in construction. BtoB向け情報検索サイト イプロス
Determines volume expansion or oil extraction rates post-chemical exposure. 💼 Industrial Applications & Elastomer Selection
Represents the maximum allowable percentage of permanent deformation after the material is subjected to prolonged compression at its designated heat-resistance testing temperature. ⚙️ Referenced Verification Standards
: The standard also accounts for physical construction, such as: : Multilayer construction. : Cloth inserted (for reinforced strength). : Teflon laminated (for improved chemical resistance). Typical Applications Rubber products conforming to JIS K 6380 are widely used in: Waterworks : Specialized EPDM types for water sealing. Industrial Sealing
When working on international projects, you may need to map JIS K 6380 to regional alternatives: Standardization Body Equivalent Standard United States ASTM / SAE ASTM D2000 / SAE J200 Germany DIN ISO 4632 jis k 6380 pdf
While broad, JIS K 6380 explicitly excludes certain rubber forms: Sponge rubber Ebonite (hard rubber) O-rings (typically covered by JIS B 2401 ) Material Classifications
And if you’re still looking for that PDF: remember that respecting the standard means using the official document. But for quick reference, the summary above gives you the soul of JIS K 6380 in under 500 words.
Testing methods for these materials are defined by related standards such as JIS K 6251 (tensile stress-strain) and JIS K 6253 (hardness). Classification System
Understanding JIS K 6380: The Standard for Rubber Material Classification : Used as flexible joints or weather-resistant covers
Rubber sheets certified under this standard are utilized across thousands of applications, including:
JIS K 6380 PDF is a valuable resource for manufacturers, suppliers, and testing laboratories involved in the production and testing of rubber products. The standard provides a comprehensive guide for testing physical and chemical properties, ensuring that products meet required specifications and regulatory requirements. While there may be some limitations, the benefits of using JIS K 6380 far outweigh the drawbacks.
JIS K 6380 standard, titled "Rubber packing material -- Classification system," provides a critical framework for identifying and categorizing rubber materials used in sealing and packing applications. While the full PDF is a copyrighted document published by the Japanese Standards Association (JSA)
The standard classifies rubber materials based on two primary environmental degradation factors: (heat resistance) and class (oil resistance). 1. Material Type (Heat Resistance) ⚙️ Referenced Verification Standards : The standard also
The classification system is structured around three hierarchical tiers:
Often classified under moderate temperature and high oil-resistance codes. Ideal for fuel and hydraulic systems.
Optimized for extreme thermal applications matching upper-tier heat-resistance letters (e.g., test ranges up to 200°C+), combined with outstanding low-temperature properties down to -30°C.
If your project involves these materials, you will need to reference other specific JIS standards.
