The purpose of this standard is to establish uniform methods for laboratory testing of air circulating fans to determine performance (forward or reverse flow) in terms of airflow rate for rating, certification or guarantee purposes.

Section/Figure/Table No.: 8.1.2 Extraneous airflow

Type of Comment: Technical (substantive)

Comment (justification):
Specification of location of extraneous airflow measurement seems to relate exclusively to test setup #1.

Proposed Change:
* Add locations of extraneous airflow measurement in each of the figures. * Delete this text from 8.1.2: "Location of extraneous airflow measurement shall be directly under the center of the fan at an elevation of 1701.8 mm (67 in.) above floor."

Section/Figure/Table No.: scope, definition

Type of Comment: Technical (substantive)

Comment (justification):
revision of my earlier proposal clearly separate 230 products from 250 products

Proposed Change:
AMCA 230 should say that circulation fans are used without ducts for recirculating air in a space primarily for temperature- or humidity-destratification of room air, or for comfort-cooling based on evaporation.
