ANSI/ASHRAE Standard 145.1-2015

ANSI/ASHRAE Standard 145.1 -2015 Laboratory Test Method for Assessing the Performance of Gas-Phase Air-Cleaning Systems: Loose Granular Media,The air around us may contain a variety of undesirable contaminants in gaseous form. Concentrations of these contaminants may vary from trace amounts to toxic levels, and at certain concentrations contaminants may become a problem for people and equipment.  When problem concentrations are present in the air-distribution system of a heating, ventilating, and air-conditioning (HVAC) system, removal may be necessary to protect building occupants; HVAC system components; building furnishings or
stored materials; and industrial/manufacturing equipment, processes, or products.

This ANSI/ASHRAE Standard 145.1 -2015 outlines a test procedure with quality control constraints to develop a performance metric using percent removal efficiency and removal capacity of a small media sample when challenged under steady-state conditions by a number of gaseous contaminants. Two groups of chemical contaminants are prescribed (the acid gas challenge group and the volatile organic compounds challenge group), and the user may select one or both groups for testing. However, all representative compounds of a group selected testing for reporting purposes.

Other challenge gases may be tested using the methodology described in this standard but are not part of the reporting requirements. The procedure  written for testing individual chemical contaminants.

Testing of mixtures of chemical contaminants, although possible using this procedure, would be considered a nonstandard test and require a much higher level of understanding, expertise, control, and analysis to achieve meaningful results.
