ASTM WK50791

    New Test Method for Thermal Effusivity Calibration of the Modified Transient Plane Source Apparatus

    (What is a Work Item?)

    Developed by Subcommittee: E37.05 | Committee E37 | Contact Staff Manager


    1. Scope

    1.1 This test method describes the calibration of the thermal effusivity signal of modified transient plane source apparatus. The range of application is 42 W s1/2/(m2 K) to 31 000 W s1/2/(m2 K) at ambient temperature. Calibration specimens are commonly right circular cylinders 2 to 3 cm in diameter and 0.1 to 3 cm in length. 1.2 SI Units are the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This standard will provide a tool for users and suppliers for the calibration of thermal effusivity apparatus. Thermal effusivity is a use preference property.

    The title and scope are in draft form and are under development within this ASTM Committee.
