The International Code Council (ICC) is a membership association dedicated to building safety and fire prevention. The ICC was established in 1994 as a nonprofit organization dedicated to developing a single set of comprehensive and coordinated national model construction codes used to construct residential and commercial buildings, including homes and schools. Most U.S. cities, counties and states that adopt codes choose the International Codes developed by the International Code Council.

The Warnock Hersey Mark is North America's most recognized product safety and performance mark for building products. Building and construction materials bearing the WHI Mark indicate to your customers and end-users product compliance to relevant building codes, association criteria, and product safety and performance standards. The mark also signifies that the product's manufacturing site(s) undergo periodic follow-up inspections to ensure ongoing compliance of the originally certified product. In short, a field inspection consists of line sampling and inspection to ensure that the product continues to be produced in the same manner as the product which was originally certified.

A WHI Mark with a “US” identifier at the 4 o'clock position indicates that the product meets US standards. A WHI Mark with a “C” identifier at the 8 o'clock position indicates that the product meets Canadian standards.
