This document (EN ISO 4404-1:2012) has been prepared by Technical Committee ISO/TC 28 "Petroleum products and lubricants" in collaboration with Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin", the secretariat of which is held by NEN. This part of ISO 4404 specifies a test method to determine the influence on metals of fire-resistant fluids in categories HFA, HFB and HFC, as classified in ISO 6743-4. The test method evaluates the corrosion protection provided by these fluids towards metal components used in hydraulic systems and installations. A similar technique for fluids in category HFD is described in ISO 4404-2.
This document replaces DIN EN ISO 4404-1:2006-11 .
