AMCA Updates Louver Debris Impact Test Method

Air Movement and Control Association (AMCA) International Inc. announces the publication of ANSI/AMCA Standard 540-23, Test Method for Louvers Impacted by Wind Borne Debris.

Superseding ANSI/AMCA Standard 540-13, ANSI/AMCA Standard 540-23 establishes uniform methods of laboratory testing the ability of a louver to remain unbreached by flying debris during a windstorm.

One of the most significant changes to the standard is the addition of instructions for mounting a louver test specimen to a test frame using angle iron. While the mounting angle now required would comply with the previous version of the standard, minimum thickness was established to ensure the mounting angle provides a rigid attachment and does not absorb appreciable amounts of impact energy from deformation.

Other changes include:

The cost of ANSI/AMCA Standard 540-23 is $45 for AMCA members and $90 for non-members in printed or PDF format and $61 for AMCA members and $122 for non-members in both printed and PDF formats. To purchase a copy, click here.
