The point at which the rubber begins to deform plastically rather than elastically (applicable to specific thermoplastic rubbers). Test Specimen Types and Preparation
When you consult the official document, the testing protocol is divided into several strict operational parameters to ensure repeatability. 1. Specimen Shapes and Dimensions jis k 6251 pdf
JIS K 6251 PDF: The Ultimate Guide to Vulcanized Rubber Tensile Testing The point at which the rubber begins to
The testing principle, as defined by JIS K 6251, is straightforward: the test piece is stretched at a constant speed using a tensile testing machine until it breaks. The machine records both the force applied and the elongation of the test piece during the entire process. Specimen Shapes and Dimensions JIS K 6251 PDF:
Smaller dumbbell samples, often used for smaller components or limited material.
While the 2017 revision aligned closely with ISO 37, there are still minor differences in dumbbell dimensions and test speeds. It is important to define in your test report whether you are strictly adhering to JIS K 6251 or ISO 37. Conclusion
