Rubber hoses and hose assemblies for bulk fuel delivery by truck — Specification
This document specifies the requirements for two groups of rubber hoses and rubber hose assemblies for loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 1,0 MPa (10 bar).
Both groups of hoses are designed for
a) use with hydrocarbon fuels having an aromatic-hydrocarbon content not exceeding 50 % by volume and containing up to 15 % of oxygenated compounds, and
b…
