What does a Certified Structural Performance Label mean?

 

• A certified Structural Performance Label provides Design Pressure information for the building code inspector.

• The manufacturer has third party independent certification that proves the designated design pressure the door system performs to.

• The third party independent certification agency is in possession of the independent test reports support these performance claims.

 

Example of NAMI Certification Label shown below

 

 

Design Pressure is a term used to identify the structural capacity of a door system. Essentially Design Pressure represents the wind load the door system can withstand.

 

What does an Affidavit Structural Performance Label mean?

• An Affidavit Structural Performance Label provides Design Pressure information for the building code inspector.

• On an Affidavit Structural Performance Label the manufacturer is affirming or promising that the designated design pressure the door system will perform to.

• The manufacturer is always the pre-hanger.

• It is assumed that the manufacturer has some evidence to support these performance claims.

• No independent testing or certification is necessarily required for the affidavit performance label.

• There is no oversight of the performance claims.
