Abstract

Overview

ISO 15615:2022 specifies safety requirements for high‑pressure devices used on the high‑pressure side of acetylene manifold systems for welding, cutting and allied processes (up to 2.5 MPa / 25 bar). The standard applies to devices such as non‑return valves, automatic shut‑off devices, three‑way valves, stop valves, pressure gauges and multifunctional safety devices. It does not cover high‑pressure piping, flexible hoses or pressure regulators.

This third edition updates test and design requirements (e.g., added pressure‑gauge requirements, clarified three‑way valve tests, removed obsolete manual/remote shut‑off valve types) and emphasizes safe design against acetylene decomposition and overpressure.

Key topics and technical requirements

Scope & definitions: Devices located on the high‑pressure side of acetylene manifold systems as defined in ISO 14114. Key device types and terms (non‑return valve, automatic quick‑acting shut‑off device, change‑over unit) are defined.
Design: Metal parts in contact with gas must be electrically continuous and designed to remain at the same electrostatic potential as the device body to prevent static discharges.
Materials: Materials shall comply with ISO 9539.
Leakage limits
- External: Tested per ISO 9090 (before and after type tests).
- Internal: Maximum internal leakage ≤ 50 cm³/h for connections with internal bore
