Selected based on the sample's thickness, elongation characteristics, or available material volume.
Specific measurements for materials that exhibit a defined yield point. Test Specimens and Equipment jis k 6251 pdf free
The percentage increase in length at the moment of rupture. Selected based on the sample's thickness
To ensure consistency, the standard specifies various test piece shapes, primarily and ring-shaped : vulcanized or thermoplastic
Testing typically requires a Universal Testing Machine (UTM) equipped with specialized grips and a long-travel extensometer to track the high elongation common in rubber products. Global Alignment: JIS K 6251 vs. ISO 37 JIS K 6251:2023 Rubber, vulcanized or thermoplastic
