If you are designing a tensile test for rubber and cannot yet access the full document, here are the core parameters defined by JIS K 6251 (based on public summaries and cross-references with ISO 37):
Industry bodies like the Rubber Manufacturers Association (RMA) or Society of Rubber Science and Technology (Japan) sometimes offer member access to bundled standards at a low fee.
JIS K 6251 is a Japanese Industrial Standard (JIS) titled "Rubber, vulcanized or thermoplastic — Determination of tensile stress-strain properties." jis k 6251 pdf free
It is the foundational standard used in Japan to test the mechanical strength of rubber materials. Whether manufacturing automotive tires, industrial seals, or rubber hoses, this standard dictates how to prove the material meets quality specifications.

The Risks of "Free" Downloads: Sites claiming to offer free PDFs of industrial standards often pose significant risks:
JIS K 6251 is a critical Japanese Industrial Standard (JIS) that specifies the methods for determining the tensile properties of rubber, vulcanized rubber, and thermoplastic elastomers. In the materials testing industry, this standard is widely referenced for quality control and research purposes. It outlines the procedures to measure essential properties such as tensile strength, elongation at break, and stress at a given elongation.
