Full title and description
JIS B 8246:2004 — Valves for high pressure gas cylinders. This Japanese Industrial Standard specifies requirements, dimensions, marking and tests for valves used on high‑pressure gas cylinders (primarily cylinders with internal volumes up to about 150 L), excluding valves for dissolved acetylene and liquefied petroleum gas cylinders.
Abstract
This standard defines the types, constructional requirements, dimensional and thread details, marking, pressure‑testing and safety provisions for valves fitted to high‑pressure gas cylinders. It includes annexes covering specific connections (for example yoke‑type/pin‑index arrangements for small medical gas cylinders) and aligns with the equivalent international document.
General information

Scope
Specifies valves for high‑pressure gas cylinders mainly used for internal volumes up to approximately 150 L; excludes valves for dissolved acetylene cylinders and liquefied petroleum gas cylinders. The standard covers valve types, principal dimensions, connection interfaces (including pin‑index/yoke arrangements used for medical small cylinders), materials, marking and required tests such as pressure and leak tests.
Key topics and requirements
- Definition and classification of valve types for high‑pressure cylinders (including handwheel, yoke, and threaded designs).
- Principal dimensions and thread specifications for cylinder attachment and filling/withdrawal ports.
- Material and manufacturing requirements suitable for high‑pressure service.
- Marking (manufacturer identification, manufacturing date, mass, proof pressure marking, gas identification where applicable).
- Pressure, leak and functional testing requirements (proof/test pressures and acceptance criteria).
- Requirements and dimensions for medical gas pin‑index / yoke‑type connections (annex), and interchangeability guidance.
- Compatibility and references to related JIS/ISO standards (specified normative references and equivalence notes).
Typical use and users
Manufacturers of cylinder valves and fittings; gas cylinder manufacturers and assemblers; bottled gas suppliers and distributors; hospitals and medical gas equipment suppliers (for small medical gas cylinders); testing and inspection bodies; standards and compliance engineers involved in high‑pressure gas systems. Practitioners use the standard to design, produce, inspect and certify valves for safe operation on high‑pressure gas cylinders.
Related standards
Commonly referenced standards include ISO 407:1991 (small medical gas cylinder pin‑index/yoke valve connections — the JIS edition notes technical correspondence), JIS B 8230 (cylinders), JIS B 8241 (seamless steel gas cylinders) and JIS B 8245 (valves for liquefied petroleum gas cylinders). The standard also cites relevant JIS metallic and tolerancing standards for threads and materials.

FAQ
Q: What is this standard?
A: JIS B 8246:2004 is the Japanese Industrial Standard that specifies requirements for valves intended for use on high‑pressure gas cylinders.
Q: What does it cover?
A: It covers valve types, dimensional and thread specifications, materials, marking, testing (pressure/leak/functional), and specific connection details such as yoke/pin‑index interfaces for small medical cylinders; it explicitly excludes valves for dissolved acetylene and liquefied petroleum gas cylinders.
Q: Who typically uses it?
A: Valve manufacturers, cylinder producers, gas suppliers, medical gas equipment providers, testing/inspection bodies and standards engineers concerned with safe design, manufacture and maintenance of cylinder valves.
Q: Is it current or superseded?
A: The 2004 edition (JIS B 8246:2004) is the current edition that superseded the 1996 edition; the document has been reaffirmed in later JIS maintenance actions. Users should confirm the current status with the official JIS/JSA catalog before relying on it for compliance.
Q: Is it part of a series?
A: Yes — it is part of the JIS series covering gas cylinders and associated components (examples: JIS B 8230, JIS B 8241, JIS B 8245). It also aligns technically with ISO 407 for small medical gas connections.
Q: What are the key keywords?
A: High‑pressure gas cylinder, valve, pin‑index, yoke, thread, marking, pressure test, JIS B 8246, ISO 407.
