NFPA 252, Standard Methods for Fire Testing of Door Assemblies

EUROLAB laboratory provides testing and compliance services within the scope of NFPA 252 standard. Fire doors play a critical role in helping to protect life and property by slowing the spread of flames, heat and gases through door openings in fire rated walls.

NFPA 252, Standard Methods for Fire Testing of Door Assemblies, details the appropriate procedures for conducting fire and hose flow tests to determine the degree to which assemblies provide adequate resistance to fire and to evaluate suitability when protection is required over a period of time.

An important document for manufacturers and test laboratories, the standard provides provisions for comparison of fire door assemblies to evaluate relevant performance under standard fire conditions.

NFPA 252 content includes:

• General management, definitions and referenced publications;
• Control of fire test including temperature-time curve, furnace temperatures and unexposed surface temperatures;
• Fire door assembly construction and size, installation, openings and test wall;
• Conducting fire test and hose flow test;
• Performance criteria for fire door assemblies, including swing and sliding doors;
• Reporting requirements and supplementary material covering explanatory, interpretive and informative references.

The purpose of this standard is to specify specific fire and hose flow test procedures for fire door assemblies to standardize a method for determining the degree of fire protection provided by such fittings in delaying the spread of fire (flame, heat and hot gases). through door openings in fireproof walls.

The degree of fire protection measured in units of time is not an absolute value, as not all possible real fire scenarios are represented by the standard fire exposure described here.

This standard allows different fire door assemblies to be compared with each other to evaluate their measured relative performance against exposure to a standard fire.
