Rubber and plastics hoses and hose assemblies — Determination of electrical resistance and conductivity
This document specifies electrical test methods for rubber and plastics hoses, tubing and hose assemblies to determine the resistance of conductive, antistatic and non-conductive hoses and the electrical continuity or discontinuity between metal end fittings.
All the test methods described for rubber hoses in this document can also be applied to plastics hoses.
