If you are looking to purchase specific materials, I can help you find manufacturers. If you have a specific material classification (e.g., a "Class A" rubber sheet) in mind, tell me what you need it for (like oil resistance or heat tolerance) and I can help you find a suitable product.

It categorizes rubber materials (like NBR, CR, Silicone, and EPDM) by their performance classes, ensuring they meet specific tensile strength, hardness, and durability requirements. Common Industrial Applications
The Jis K 6380 PDF offers several advantages, including:
Materials specifically for sponge rubber, ebonite, and O-rings (the latter often governed by JIS B 2401). Classification of Rubber Materials
A numeric value indicating the Durometer (typically Shore A) hardness required for the seal.
Measures the material's ability to return to its original shape after being compressed. Where to Obtain the PDF
Once you have the , do not just file it away. Integrate it into your quality management system:
The Japanese Standards Association (JSA) is the official publisher. They offer secure PDF downloads of the standard in both Japanese and English translations.
Matches the highest Type and Class designations for extreme chemical and thermal resistance.
The Japanese Industrial Standard is the cornerstone specification defining the classification, physical properties, and performance metrics of rubber materials used for industrial packings, gaskets, and similar sealing products.
For decades, the standard was aligned with the now-withdrawn ISO 4632-1. Recognizing its continued importance in the Japanese market, the 2014 revision focused on clarifying the content, particularly the performance notation system, based on user feedback.
This standard is primarily used in Japanese industrial and automotive manufacturing for: O-rings and Gaskets : Ensuring material compatibility with fluids. Industrial Seals : Standardizing parts across different suppliers. Quality Control

Translate specific line call-outs on engineering blueprints into physical rubber properties.
Based on industrial practices for these standards, here is how you generally prepare a piece:
: Relied heavily on older matrix tables to select and cross-reference industrial rubber variants.
