ASHRAE 137 Measurement of Thermal Input in HVAC Appliances Laboratory Testing Service: A Comprehensive Guide

The measurement of thermal input in Heating, Ventilation, and Air Conditioning (HVAC) appliances is a critical aspect of ensuring the efficiency, safety, and reliability of these systems. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has established Standard 137, which provides guidelines for measuring the thermal input of HVAC appliances.

Relevant Standards

  • ASHRAE Standard 137: Measurement of Thermal Input in HVAC Appliances

  • ISO 5167: Measurement of Fluid Flow by Means of Pressure Differential Devices Inserted in Circular Cross-Section Conduits Running Full or Variable Attenuation Devices

  • ASTM E1116: Test Method for Measuring Thermal Input to HVAC Appliances

  • EN 13141: Measurement of the Thermal Output and Efficiency of Combustion Installations

  • TSE (Turkish Standards Institution) 1619: Measurement of Thermal Input in HVAC Appliances

    • International and National Standards

    ASHRAE Standard 137 is an international standard, but it has been adopted by various national standards institutions around the world. For example:

  • In Europe, EN 13141 is used as a reference standard for measuring thermal input.

  • In Turkey, TSE 1619 is the national standard for measuring thermal input.

    • Standard Development Organizations

    ASHRAE is one of the leading organizations responsible for developing and maintaining standards related to HVAC systems. ASHRAE has over 50,000 members worldwide and is involved in various international collaborations with other standards development organizations (SDOs).

    Evolution and Updates of Standards

    Standards are living documents that evolve over time as new technologies and research emerge. SDOs continuously review and update existing standards to ensure they remain relevant and effective.

    Standard Numbers and Scope

    The following table provides a summary of the relevant standard numbers, their scope, and applicability:

    Standard Number Title Scope
