Overview
EN 13308:2002 (CEN) specifies requirements for the non pressure balanced footvalve used in tanks for transport of dangerous goods. The standard covers performance, critical dimensions and required tests for footvalves used for bottom loading and unloading of flammable liquids (ADR Class 3) with vapour pressure ≤ 110 kPa at 50 °C and petrol, excluding toxic or corrosive sub‑classes. It defines design, mounting, actuation, break‑away security, materials and test regimes to verify compliance.
Key Topics and Technical Requirements
- Scope & application: Footvalves for bottom loading/unloading of road tankers transporting Class 3 liquids (vapour pressure ≤ 110 kPa) and petrol.
- Pressure and sizing:
- Minimum working pressure (design): 500 kPa (MAWP).
- Nominal bore: designed for DN100 pipe.
- Bottom loading flow: suitable up to 150 m³/h at up to 500 kPa.
- Mounting & dimensions: Tank mounting and run‑off flange dimensions specified in Annexes A–C (normative).
- Actuation & safety:
- Externally actuated (mechanical, pneumatic or other).
- Self‑closing: valve must close if actuation fails or is disconnected (except during loading).
- Open position must be visible; emergency mechanical operation may be provided.
- Prevents inadvertent opening from impact or accidental action.
- Break‑away security:
- Valve seat located within tanker envelope.
- External housing designed to break away while leaving internal sealing intact.
- Maximum impact energy to break away external housing: ≤ 1 kJ.
- Materials & electrical:
- Manufacturer must supply material specs for wetted parts.
- Electrical resistance requirements: conductive parts to valve body ≤ 10^6 Ω; bonding from valve to tank ≤ 10^5 Ω.
- Strainer: Valve must accept a strainer to prevent foreign objects impairing closure.
- Temperature range: Default −20 °C to +50 °C (extendable to −40 °C or +70 °C where needed).
- Testing & conformity:
- Production and type tests per prEN 12266‑1 / EN 12266‑2 and sampling per ISO 2859‑1 (AQL 2.5).
- Production tests: shell tightness, seat tightness (20 kPa), operability.
- Type tests: shell strength, tightness, operability, mechanical endurance, break‑away, etc.
Applications and Users
- Who uses EN 13308:2002:
- Tank and tanker manufacturers, service‑equipment suppliers.
- Fleet operators and maintenance teams for road tankers.
- Third‑party inspectors, conformity assessment bodies and test laboratories.
- Regulatory and compliance professionals working with ADR/RID requirements.
- Practical uses:
- Specify and procure compliant non pressure balanced footvalves for bottom loading/unloading systems.
- Design validation, factory production control and type approval testing.
- Maintenance, inspection and incident mitigation planning (break‑away behavior, bonding).
