About This Item
This standard provides rules for the testing of central system humidifiers for residential applications. Its purpose is to provide a uniform method for testing in a laboratory environment. Although the method of test originated in AHRI Standard 610, Performance Rating of Central System Humidifiers, the project committee has developed this separate method of test to be used independently of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) rating standard so that manufacturers, specifiers, installers, and users of central-system residential humidifiers can test a humidifier’s capacity under a variety of conditions with uniform results. This method of test was prepared in cooperation with AHRI to correspond with AHRI Standard 610.
The scope of this standard covers a method of test for measuring the humidification rate of central-system residential humidifiers intended for use with forced-warm-air heating and/or cooling systems. This method of test describes the test apparatus, mode of test conduction, and information to be recorded. Tests covered include methods for measuring electrical power input, water flow rate, water temperature, and water pressure to the test humidifier. Also included are airflow rate, static pressure, temperature, and relative humidity entering and maintained by the test apparatus. Information resulting from the application of this test method is intended for use by manufacturers, specifiers, installers, and users of central-system residential humidifiers. This test method does not apply to self-contained humidifiers, portable humidifiers, or humidifiers for commercial and industrial applications.
This is a reaffirmation of the 2012 edition of the standard.
