JIS (Japanese Industrial Standards) are the national standards coordinated by the Japanese Industrial Standards Committee (JISC). They are organized into divisions identified by a single letter and are widely used across Japanese industry.
Why JIS standards matter in testing
A JIS test standard defines the specimen, apparatus, and procedure used for acceptance and quality control in Japan, with many methods aligned to the equivalent ISO standard.
What JIS standards cover
JIS standards are grouped into lettered divisions; the ones most relevant to mechanical testing are:
| Division | Scope |
|---|---|
| Z | General / testing methods (e.g. JIS Z 2241 metallic tensile) |
| G | Ferrous materials and metallurgy |
| H | Nonferrous materials and metallurgy |
| K | Chemical products, plastics, and rubber |
| P | Pulp and paper |
How to read a JIS designation
JIS designations use a division letter and a number:
| Part | Example | Meaning |
|---|---|---|
| Division | Z | Subject division (here, general test methods) |
| Number | 2241 | Sequential standard number (metallic tensile) |
| Year | (:2011) | Optional year of issue or revision |
