Description (English):

This document specifies the requirements for design, specification, type testing and production testing and inspection of dedicated LPG manually operated cylinder valves for use with and directly connected to transportable refillable LPG cylinders. It also includes requirements for associated equipment for vapour and liquid service. Bursting discs and/or fusible plugs are not covered in this document. Annex B identifies requirements for production testing and inspection. This document excludes other LPG cylinder devices which are not an integral part of the dedicated manually operated cylinder valve. This document does not apply to cylinder valves for fixed automotive installations and ball valves. NOTE For self-closing LPG cylinder valves see ISO 14245. For cylinder valves for compressed, dissolved and other liquefied gases see ISO 10297,[2] ISO 17871[6] or ISO 17879[7].

Abstract

Overview

EN ISO 15995:2021 - "Gas cylinders - Specifications and testing of LPG cylinder valves - Manually operated" is a CEN-adopted international standard that defines design, specification, type testing, production testing and inspection requirements for dedicated manually operated LPG cylinder valves used on transportable refillable LPG cylinders. The standard also covers associated equipment for vapour and liquid service, while explicitly excluding bursting discs/fusible plugs, fixed automotive installation valves and ball valves. Annex B addresses production testing and inspection requirements.

Key topics and technical requirements

The document organizes technical requirements and tests that ensure safety, reliability and compatibility of LPG cylinder valves. Major topics include:

Design and specification
- General design rules, essential and optional components (valve body, stem, outlet, excess flow devices, pressure relief valves, eduction tubes, liquid level indicators, sealing caps, sediment tubes).
- Material selection and operating temperature considerations, including metallic and non‑metallic component guidance.
Performance and safety requirements
- Leak tightness (external and internal), operating, opening and closing torque limits.
- Requirements for excess flow valves and non‑return valves where applicable.
Type testing
- Hydraulic pressure tests, valve stem tests, hand‑wheel fire exposure tests, impact tests, excessive opening/closing torque tests, endurance (cycling) tests.
- Examination of dismantled valves and inspection criteria after testing.
Production testing and inspection
- Annex B identifies mandatory production checks and inspection steps to maintain conformity in manufacturing.

Practical applications and who uses this standard

EN ISO 15995:2021 is used to ensure safe operation and regulatory compliance of manually operated LPG cylinder valves across the supply chain. Typical users include:

LPG cylinder valve manufacturers - for design validation, type approval and production quality control.
Test laboratories and certification bodies - to perform type tests and verify conformity to EN ISO 15995:2021.
LPG equipment designers and OEMs - for specifying compatible valve features and associated equipment (vapour/liquid service).
Regulatory authorities and safety inspectors - to assess compliance, installation safety and marketplace surveillance.
Service centers and cylinder refillers - to understand valve characteristics, torque limits and replacement criteria.
