ISO 20843:2011 specifies a test method to determine the pH value of fire-resistant fluids within categories HFAE, HFAS and HFC, as classified in ISO 6743‑4.
Abstract
Overview
ISO 20843:2011 specifies a laboratory test method for the of fire‑resistant hydraulic fluids classified as (per ). The standard describes sampling, measurement conditions and reporting rules used to monitor aqueous hydraulic fluids where pH variations may indicate contamination, bacterial proliferation or loss of corrosion protection.
