Scope

This document specifies a suite of screening test methods to determine the thermal stability, emulsion stability and foaming characteristics of water mix metal working fluids.

These tests do not provide an assurance that a water mix metal working fluid is suitable for a particular metalworking application.

Part A, Evaluation of the thermal stability of the water mix metal working fluid concentrate.

Part B, Evaluation of the emulsion stability of a water mix metal working fluid concentrate.

Part C, Evaluation of the foaming characteristics of the emulsion produced from a water mix metal working fluid concentrate.

Annex A gives details of how to prepare the emulsion required for Part B and Part C.

NOTE - For the purposes of this standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.
