ISO/PWI 3032.2 Standard Test Method for Measuring Equivalent Thermal Conductivity Constant of fire protection coatings

Scope

This standard provides a measuring procedure, designed to assess the equivalent thermal conductivity constant of coatings for fire protection of steel structures.

Purpose

Steel structures are not inherently fire resistant because much of the strength of steel is lost when the steel temperature reaches 600oC or above during a fire. Fire resistance of steel structures has traditionally been ensured by applying insulating materials around the steelwork, such as sprays, boards, blankets, and intumescent coatings. An accurate and effective assessment of their thermal properties is essential for structural fire design of steel structures and quality inspection of fireproofing products. This proposal presents a simple and effective measuring method to assess the equivalent thermal conductivity constant of sprayed and intumescent coatings, respectively. The proposed method is to address the challenges in determining the temperature-dependent thermal conductivity of sprayed coatings, and thickness-dependent thermal conductivity of intumescent coatings as they expand when exposed to fire. The measured results can be easily used to determine the temperature of protected steel members, thus simplifying the design procedure of steel structures in fire and standardizing the quality control of fireproofing products.
