Annex
A (normative) Method of test for electrical conductivity
Defines requirements for two types of textile reinforced themoplastics hoses and hose assemblies having maximum working pressures in the 69 - 345 bar range. For use with petroleum and synthetic based hydraulic fluids in temperature range -40 deg C to +100 deg C, and water based hydraulic fluids in temperature range 0 deg C to +70 deg C. Requirements for end fittings are not given - limited to hose and hose assemblies performance.
