The maximum stress a rubber material can withstand while being stretched before breaking.
The Japanese standard, heavily harmonized with ISO but featuring distinct historical specimen dimensions (such as the Type 3 dumbbell).
Note: As of December 2023, the 2017 version has been succeeded by newer updates, though the 2017 version is still widely used in established workflows. Summary of Testing Procedure jis k 6251 pdf free
A tensile testing machine (often called a Universal Testing Machine or UTM) equipped with precise load cells and extensometers is required.
The percentage increase in length a test piece experiences at the moment of breakage. The maximum stress a rubber material can withstand
The maximum stress a rubber sample can withstand before breaking.
Used when raw material volume is limited or when cutting specimens from finished commercial products (like seals, hoses, or O-rings). Ring-Shaped Specimens Summary of Testing Procedure A tensile testing machine
A tensile testing machine with constant rate of traverse (CRT) and constant rate of elongation (CRE).
JIS K 6251 is a prominent material standard published by the Japanese Standards Association . It details the exact methods required to determine the of vulcanized and thermoplastic rubbers.
The stress required to stretch a test piece to a given elongation (commonly measured at 100%, 200%, or 300% elongation).
