  • Description

    Use the latest test method for pipe insulation assemblies that contribute less heat, flame, and smoke in fire scenarios. NFPA 274 is up-to-date with NFPA codes and standards for state-of-the-art information.

    Essential for testing laboratories and manufacturers, NFPA 274: Standard Test Method to Evaluate Fire Performance Characteristics of Pipe Insulation is used to determine the heat release and smoke generation of pipe insulation and pipe insulation assemblies under controlled laboratory conditions. A method is provided for an examination of the complete insulation assembly including elbows in an actual end use configuration.

    The 2018 edition of the Standard provides full coverage on:

    • Test specimens
    • Test equipment and instrumentation
    • Calibration
    • Procedure
    • Calculations
    • Report of results

    Updated code and standard references improve consistency and usability for users. (Print, 20 pp., 2018)
