Overview
EN 14596:2018 - Tanks for transport of dangerous goods - Service equipment for tanks - Emergency pressure relief valve - is a European (CEN) standard that defines performance, critical dimensions and required tests for emergency pressure relief valves fitted to road tank and vehicle-mounted tanks. The standard applies to valves used with flammable liquid substances (ADR Class 3) with a vapour pressure not exceeding 110 kPa at 50 °C (including petrol), and excludes substances sub‑classified as toxic or corrosive. EN 14596:2018 clarifies functional requirements (open/close/contain), design characteristics and mandatory production and type testing.
Key topics and requirements
- Functionality: Valve must open to relieve excess pressure, re‑close after relief and contain the tank contents when closed. Not intended as a pressure‑vessel safety valve under ADR.
- Relieving pressure: Manufacturer must specify relieving pressure. It must exceed the pressure arising from 110% of the static head of the densest product plus the relieving pressure of the compartment breather device.
- Design limits: Maximum external height above mounting face is limited (150 mm when fully open). Weather protection must prevent water accumulation and freezing without impairing operation.
- Materials & electrical properties: Manufacturers must provide material specifications for wetted parts. Electrical resistance limits for conductive parts and bonding provisions are defined to control static discharge risk.
- Temperature range: Designed to operate across specified temperature ranges (standard upper limit +50 °C unless otherwise stated).
- Testing regime: Two classes of tests:
- Production tests (sampling per ISO 2859‑1): seat tightness (test pressure 65 kPa) and relieving pressure checks (reseat pressure ≥ 0.8 × specified relieving pressure).
- Type tests: include seat tightness, relieving pressure, drop test (to assess structural integrity after roll/impact scenarios) and vapour venting performance. Test methods reference EN 12266 and additional annexes (drop rig, venting capacity table).
Applications and who uses it
- Tank manufacturers and designers - to specify compliant emergency relief valves on gravity discharge tanks.
- Component suppliers - for product development, type testing and CE/national standard compliance.
- Operators, fleet owners and maintenance teams - to select, install, inspect and maintain service equipment that meets safety and regulatory expectations.
- Test laboratories and certification bodies - to perform production and type tests and verify conformity.
- Regulators and inspectors - to assess compliance with ADR‑related equipment requirements.
