ARLINGTON HEIGHTS, Ill. — Air Movement and Control Association (AMCA) International Inc. has published ANSI/AMCA Standard 500-L-23, Laboratory Methods of Testing Louvers for Rating.
Superseding ANSI/AMCA 500-L-2012 (revised in December 2015), ANSI/AMCA Standard 500-L-23 establishes uniform methods of testing air leakage, air performance (pressure drop), water penetration, resistance to wind-driven rain and wind-driven-sand, and operational torque. The standard may be used as a basis for testing louvers with air as the test gas.
Changes to ANSI/AMCA Standard 500-L include:
• The addition and clarification of definitions.
• Improvements to the water-performance test rig and calibration procedure.
• Improvements to the wind-driven rain test.
• The addition of a section on free-area measurement.
• Updated constants in equations for agreement with ANSI/AMCA Standard 210-16/ASHRAE Standard 51-16, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating.

• Updated louver-leakage procedure harmonized with ANSI/AMCA Standard 500-D-18, Laboratory Methods of Testing Dampers for Rating.
• Clarification of, and the provision of additional details on, louver core-area measurement.
• The addition of discharge-loss coefficient and class calculation.
The cost of ANSI/AMCA Standard 500-L-23 is $90 in either printed or PDF format, and $122 in both printed and PDF formats. To purchase, click here.
