It provides requirements for the tensile testing machine, load cells, and extensometers, ensuring the machinery is accurate enough to measure the forces applied.
The stress required to stretch a test piece to a given elongation (typically 100%, 200%, or 300%).
This value is calculated by dividing the maximum force recorded during the test by the original cross-sectional area of the specimen. The result is expressed in . The cross-sectional area (A) is calculated as the product of the width (W) and thickness (T) of the specimen's parallel part. If you're interested in equivalent standards, you may

The machine must feature grips (such as pneumatic or self-tightening wedge grips) that tighten automatically as the tensile force increases, preventing sample slippage.
The most reliable sources for the official PDF are the authorized distributors of Japanese Industrial Standards. These include:
Secure the specimen in the grips and pull at the specified speed (typically for standard dumbbells).
