Specific stress and elongation measurements for materials that exhibit a distinct yield point. Testing Methodology

Used less frequently but allowed for specific applications where dumbbell cutting is impractical. Thickness: Generally between , measured precisely before the test. 4. Testing Procedure Conditioning: Samples must be kept at a controlled temperature (usually ) for at least 3 hours before testing. JIS K 6251 is largely harmonized with ISO 37

While is based on ISO 37:2017 (Rubber, vulcanized or thermoplastic — Determination of tensile stress-strain properties), it is classified as "MOD" (Modified). This means that while they are generally interchangeable, slight differences in sample sizes (specifically the dumbbell shapes) may exist.

EB=Lb−L0L0×100cap E sub cap B equals the fraction with numerator cap L sub b minus cap L sub 0 and denominator cap L sub 0 end-fraction cross 100 EBcap E sub cap B = Elongation at break (%) Lbcap L sub b = Gauge length at the moment of rupture (mm) L0cap L sub 0 = Original gauge length (mm) Comparison: JIS K 6251 vs. ISO 37 vs. ASTM D412 it is classified as "MOD" (Modified).

These parameters provide a complete picture of how a rubber product will behave under mechanical stress, helping to predict its performance in real-world applications such as seals, tires, hoses, and vibration dampeners.

Free previews of both the Japanese and English PDFs are available on the JSA Webdesk website, allowing you to review the table of contents and initial sections before purchasing. This is a valuable feature for verifying that you are obtaining the correct standard for your needs.
