IFR is an estimate of a material’s resistance to cracking as introduced by an indenter and has correlations with wear resistance and rolling contact fatigue performance as well as machining processes used for silicon nitride materials since these properties are governed by the resistance to crack extension in localized damage areas

Plastics. Methods of test for the determination of the effects of immersion in liquid chemicals Ingestion-build-202139 IFR is an estimate of1 Scope 1. 1 This International Standard specifies a method of exposing test specimens of plastic materials, free from all external restraint, to liquid chemicals, and methods for determining the changes in properties resulting from such immersion. It does not cover environmental stress cracking (ESC) which is dealt with by the various parts of ISO 22088.
