This standard offers a testing method to measure and describe the ignitability characteristics of exterior wall assemblies and their potential of contributing to fire growth under controlled …

Manufacturers and testing labs depend on criteria in NFPA 268 to evaluate ignitability characteristics of exterior wall assemblies and other components.

Standard: NFPA 268 – Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source. Scope: NFPA 268 measures the ignitability of exterior wall assemblies based on a standardized heat flux exposure. The exposure is specifically calibrated to simulate a specific fire separation distance based ...

This standard offers a testing method to measure and describe the ignitability characteristics of exterior wall assemblies and their potential of contributing to fire growth under controlled laboratory conditions.

This edition of NFPA 268, Standard Test Method for Determining Ignitibility of Exterior Wall Assemblies Using a Radiant Heat Energy Source, was prepared by the Technical Committee on Fire Tests. It was issued by the Standards Council on July 28, 2006, withan

The 1996 edition of NFPA 268 represented the €rst edition of a standard that addressed the determination of ignitability characteristics of exterior wall assemblies. The test method incorporated a radiant heat energy source. At the time this document was published, there were no standardized test methods available within the standards ...

2017年1月1日 · This fire test response standard describes a method for determining the propensity of ignition of exterior wall assemblies from exposure to 12.5 kW/m 2 (1.10 Btu/ft 2 -sec) radiant heat in the presence of a pilot ignition source.

2022年1月1日 · NFPA 268, 2022 edition, outlines the methods for deciding the susceptibility of exterior wall assemblies to fire in the presence of a pilot ignition source. The document answers the need for standardized test procedures that complement fire test methods available within existing NFPA standards.

NFPA 268 运用辐射热源的内墙点燃性的标准测试，NFPA 268是将1.2m×2.4m试验样品暴露在12.5kW/m2的热流下并强制点燃20分钟。 南京睿督公司咨询电话：025-86583475
