The American National Standard Institute has developed many of the standards and tests used to determine fenestration product code compliance. In accordance with ANSI fire labeling requirements, door and frame manufacturers must hire independent agencies to test their products and assess their code ratings. Benchmark Doors are assessed by Intertek Testing Services, using the  Warnock Hersey certification mark.

Intertek Testing Services tests doors, frames and door & frame assemblies for fire door applications, and provides Warnock Hersey certification labels to manufacturers for product lines which successfully pass the tests. 

Benchmark offers a broad spectrum of residential steel doors and frames with the Warnock Hersey certification mark. A nominal fee is charged for the use of the WHCM.

Some building code inspectors will accept a manufacturer's affidavit label which asserts the code values given for a particular application. Affidavit labels are available free of charge.

Another cost saving option regarding fire labels is Benchmark's fire rated system. Fire rated systems require only one tested fire label, cutting the labeling requirement and the cost in half. Fire rated systems include listed assemblies for the door opening, frame and other materials.
