Scope

This standard specifies the minimum allowable values of energy efficiency,
evaluating values of energy conservation, and test methods for centrifugal blowers.
This standard applies to single-stage dual-support low-speed centrifugal blowers;
multi-stage low-speed centrifugal blowers; single-stage dual-support high-speed
centrifugal blowers (including single-side impeller of dual-inlet blower); and
multi-stage high-speed centrifugal blowers.
