EN16643 Hose Assembly Electrical Property Grades

The hose assembly electrical property grades and electrical resistance limits are defined within EN 16643 and tested in accordance with BS EN ISO 8031. Aflex Hose electrically conductive (EC) assemblies are defined in EN16643 as electrically bonded and given the symbol M. M-grade assemblies exhibit a maximum electrical resistance of 100Ω between end fittings. Aflex Hose anti-static (AS) PTFE liners and rubber covers are termed static dissipative within EN 16643 and given the symbol Ω followed by letters that specify either the liner, cover or both; L=liner, C=cover, CL= cover & liner. Ω-grade covers or liners exhibit an electrical resistance of 103-108Ω.

The table below identifies each EN 16643 electrical grade for a hose assembly along with a brief description and example assembly configuration.
