The purpose of this document is to prescribe and establish procedures to be used in the development and publication of certified performance ratings for airflow measurement stations. Certified ratings provide assurance to the buyer, user, and specifier that the manufacturer's published performance ratings for airflow measurement stations are repeatable; information on how the product was tested; what appurtenances (accessories or optional equipment) were accounted for in the ratings; and other pertinent information.

This standard provides a procedure for verification of the manufacturer's performance ratings on a regular schedule through check-testing of products in the AMCA International Laboratory.

This standard provides assurance that competitive ratings are comparable at the point where the output data is acquired, and that they are based on standard test methods on ratings procedures.

This program applies to products or systems that output either analog electronic (E) or non-electronic (NE) signals. A non-electronic output is considered analog differential pressure, which requires additional hardware to convert differential pressure to an electronic signal.
