ASTM WK24833

    New Guide for Using Calorimetry for Emergency Relief System Design

    (What is a Work Item?)

    Developed by Subcommittee: E27.02 | Committee E27 | Contact Staff Manager


    1. Scope

    1.1 This guide covers suggested procedures for the operation of calorimetric devices designed to obtain temperature and pressure data as a function of time for purposes of emergency relief system design. For emergency relief system design it is preferable to use low phi-factor testing. 1.2 This guide covers both closed system tests and open system tests and addresses vapor, gassy, and hybrid runaway reaction behavior. 1.3 Guidance is provided on the determination of self-heating and pressure rates and other parameters important for emergency relief system design. 1.4 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 to determine the applicability of regulatory limitations prior to use.


    adiabatic calorimetry; pressure relief; low phi factor


    To assist users in getting the most appropriate and accurate data for use in designing emergency relief systems

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