    Help ensure building materials meet appropriate levels of fire safety by referencing the latest requirements in NFPA 703.

    Choosing the proper building materials plays a critical role in helping to protect lives and property in the event of a fire. NFPA 703, Standard for Fire-Retardant-Treated Wood and Fire-Retardant Coatings for Building Materials, provides code enforcers and AHJs, engineers, producers, and architects with the information you need to make the correct decisions in your work.

    This standard offers comprehensive criteria for defining and identifying fire-retardant-treated wood (FRTW) and fire-retardant-coated materials. You get the provisions needed to understand how fire-retardant-treated wood works and how to accurately and efficiently classify and test it.

    This edition is updated to reflect the most current expert knowledge and best practices.

    The revised NFPA 703 is your source for the most relevant requirements for the exterior and interior application of fire-retardant-treated wood, labeling, and effects of exposure to environmental conditions. Annexes provide explanatory material and informational references.

    Changes to the 2021 edition include:

    • Revised testing criteria for fire-retardant-treated wood to better coordinate the requirements with standard industry practice
    • New explanatory material to clarify the difference between coating and impregnating
    • Updates to referenced codes, standards, and other documents

    Get the resource you need to verify building materials are correctly classified and tested and to increase confidence in fire safety.
