EN 12115 — chemical transfer hoses
EN 12115 is the European standard for rubber and thermoplastics hoses used to transfer chemicals and liquid petroleum products. It classifies hoses by electrical type — conductive (Ω/T) or antistatic (M) — and sets requirements for chemical resistance, pressure, marking and traceability so aggressive media can be loaded and unloaded safely.
EN 12115 is the European standard for rubber and thermoplastics hoses and hose assemblies used to transfer chemicals — liquid or gaseous — and liquid petroleum products. It is the reference for tank-truck loading, plant transfer lines and bulk handling of aggressive media.
Scope
The standard applies to assemblies, not just the bare hose: it covers the hose, the couplings and the way they are bonded together, because electrical continuity through the whole assembly is critical when handling flammable or static-prone liquids.
Electrical classification
| Type | Code | Meaning |
|---|---|---|
| Conductive | Ω / T | Continuous electrical path through the hose to earth |
| Antistatic | M | Controlled dissipation of static charge |
Key requirements
- Chemical resistance of the inner tube to the specified media.
- Defined working pressure, test pressure and burst pressure.
- Electrical continuity verified across the complete assembly.
- Durable marking and traceability of each assembly.
- Resistance to ageing, ozone and weather in the cover.
How to select
Start from the chemical to be transferred and match it against the tube compound's resistance. Choose the electrical type (conductive or antistatic) required by the site, then confirm bore, pressure rating, length and the coupling type. Because EN 12115 governs the assembly, fittings must be installed and bonded so that continuity is maintained.
Compatibility
Chemical compatibility must always be checked against a resistance chart for the exact medium and concentration. The same hose family can serve different products only where the tube compound is confirmed compatible.
Frequently asked questions
It covers rubber and thermoplastics hose assemblies for transferring chemicals and liquid petroleum products, including their couplings and electrical continuity.
Ω and T indicate conductive hoses with a continuous earth path, while M indicates antistatic construction that dissipates static charge in a controlled way.
Always compare the exact medium and concentration against a chemical resistance chart for the tube compound before selecting an EN 12115 hose.
