testing of a manufacturer’s equipment to verify published performance.

The overall objective of KWMK b(also known as KbRaKO b ;7), titled “Laboratory Methods of Testing Fans for Rating,” is to promote consistent testing methods for fans, blowers, exhausters, and some types of air compressors.

The Air-Conditioning & Refrigeration Institute (ARI) has similar standards for fans that are a part of equipment such as fan coils, central-station air handlers, unit ventilators, and water-source heat pumps. These standards, such as KaS

bfor central-station air handlers, account for the effects of the air handler casing around the fan and establish rating, testing, and certification standards for equipment manufacturers.
