Summary This standard specifies the use of an external ignition time, the sample can be controlled at the level of positioning by the thermal radiation levels measured heat release rate method. Heat release rate is measured by the oxygen concentration in the combustion product gas stream of oxygen consumption and the calculated flow rate of combustion products to determine, colleagues of the sample ignition (combustion flame continued) time is measured.

Foreword

This standard is identical with ISO 5660-1.2002 "Reaction to fire tests heat release, smoke production volume and mass loss rate - Part 1. Thermal The release rate (cone calorimeter method) "(in English). This standard is equivalent translation ISO 5660-1.2002. For ease of use, this standard made the following editorial changes. a) "this International Standard" be replaced by "this standard"; b) use a decimal point instead of a decimal comma ",". ","; c) Remove the preface to international standards. This standard replaces GB/T 16172-1996 "building materials heat release rate test methods", because the development of international standards in the original technology The technique is obsolete; this standard and GB/T 16172-1996 compared to major differences are. --- Adds definitions of terms in the entry; --- Adds a symbol chapter; --- Increasing the radiation shield and optional shield; --- Increased the short burn time material data acquisition cycle requirements; --- Increased the size of the unstable material preparation requirements; --- Increasing the test sample substrate selection requirements and maintenance requirements; --- Increased non-recurring pre-calibrated and update calibration, calibration work requirements; --- Change the maximum data acquisition time and the shortest test time; --- Increased testing and calculated mass loss rate; --- Increased by 6 informative appendix.

This standard replaces the standards previously issued as follows. --- GB/T 16172-1996. GB/T 16172-2007/ISO 5660-1.2002 Test methods for building materials heat release rate

1 Scope

This standard specifies using an external ignition, positioned horizontally in the sample can be controlled by the level of thermal radiation, heat release rate was measured square law. Heat release rate is determined by measuring the combustion product gas stream oxygen concentration calculated oxygen consumption and combustion products flow , But also to sample ignition (sustained flaming) time was measured.

3 Terms and Definitions

ISO 13943 and the following terms and definitions apply to this standard established. 3.1 Unevenness of the plane are within ± 1mm surface. 3.2 Appears above the sample surface or flame duration of less than 1s of combustion phenomena. 3.3 Sustained flame (see 3.10). 3.4 < On the surface IT> element is incident on the surface of the sample surface at a point on (and including the point of the unit area) of the radiant flux divided by the surface Yuan area. NOTE. When horizontal positioning on the sample convective heat transfer is negligible. Thus, the standard term "irradiance" instead of "heat", so it can better show radiation It is the main mode of heat transfer. 3.5 A single substance or a mixture of uniformly distributed. Such as metal, stone, wood, concrete, mineral fiber and polymer. GB/T 16172-2007/ISO 5660-1.2002
