Abstract

Overview

ISO 14245:2021 - "Gas cylinders - Specifications and testing of LPG cylinder valves - Self-closing" specifies design, type testing, production testing and inspection requirements for dedicated self-closing LPG cylinder valves used on transportable refillable LPG cylinders. The standard covers valves for both vapour and liquid service and related integral equipment, and it is written to be suitable for reference in the UN Model Regulations. It explicitly excludes bursting discs and fusible plugs, non-integral LPG devices, fixed automotive cylinder valves and ball valves.

Key topics and technical requirements

ISO 14245:2021 defines requirements across design, materials, components and a comprehensive suite of tests. Major topics include:

Design and specification
- Materials, operating temperatures, copper alloys and non‑metallic material guidance
- Essential components: valve body, stem, outlet, operating mechanism and excess flow elements
- Optional components: pressure relief valves, eduction tubes, liquid level indicators, non‑return valves, sealing caps, sediment tubes
Type testing and inspection
- Hydraulic pressure tests, external and internal leak tightness testing
- Operation and valve stem tests to verify correct functioning and durability
- Impact, endurance and vibration tests to assess resistance to mechanical shock, cyclic operation and dynamic loading
- Excess flow and non‑return valve tests for specific subcomponents
- Simulated vacuum test and dismantled valve examination for internal compliance
Production testing and markings
- Normative Annex A specifies production testing and inspection requirements
- Marking provisions for traceability and regulatory compliance
Special conditions
- Annex B: low temperature requirements
- Annex C: vibration testing procedures

Applications and who uses this standard

ISO 14245 is essential for stakeholders involved in LPG cylinder safety, manufacturing and regulation:

Valve manufacturers - to design and certify self‑closing LPG cylinder valves to recognized international requirements.
Cylinder and LPG equipment manufacturers - to ensure valve compatibility and safe integration for transportable refillable cylinders.
Testing and certification laboratories - to perform type testing, production inspection and test reporting per the standard.
Regulators and conformity assessment bodies - to reference in approvals, national regulations and UN Model Regulations.
Purchasing engineers and safety managers - for procurement specifications and verifying supplier compliance.
