After many years of development, the ISO 9950 standard describing cooling curve analysis of quench oils without agitation has been issued. There is also a related standard being balloted within ASTM. The next step of this ongoing work, within both the IFHT and ASM Quenching and Cooling Committees to develop standards for cooling curve analysis of vaporizable quenchants with agitation. This will involve the development of two different standards. One will expand on ISO 9950 and provide for cooling curve analysis using the {open_quote}Wolfson Probe{close_quotes}, 12.5 x 60 mm INCONEL 600 with a Type K thermocouple inserted into the geometric center The second method to be developed will measure the surface rewetting properties of a quenchant by measuring the variation of conductance of a {open_quotes}standard{close_quote} probe. This paper will provide an overview of currently existing national standards and describe the experimental procedures for the new standards incorporating agitation which are being developed.
