Summary	This standard specifies the test methods used to evaluate the performance of composite sandwich panels for building body burning. Flame with specific products to evaluate the direct effect on the composite sandwich construction surface or internal flame propagation characteristics, in the building at the corner of the room, through simulated indoor fire conditions. The tests do not assess products against fire resistance, this part of GB/T 25206 requirements composite sandwich panels can be self-supporting and building body frame support and other structures. But only for the building of the wall, ceiling or roof structure to be tested.

Foreword

GB/T 25206 "sandwich composite construction body combustion performance test" is divided into two parts. --- Part 1. cell method; --- Part 2. Large chamber method. This section GB/T Part of 225,206. This part identical with ISO 13784-2.2002 "the burning behavior of composite sandwich panels body building - Part 2. Large Chamber Method" (in English). This section is equivalent translation ISO 13784-2.2002. For ease of use, this section made the following editorial changes. a) "international standard in this part of the" replaced by "this section"; b) use a decimal point instead of a decimal comma ",". ","; c) Delete "in the normative references in ISO 13784-1 composite sandwich construction bodies burning performance testing - Part 1. Small room Law "because it is not in the standard ISO 13784-2.2002 appears in this section are not referenced. This section presents the People's Republic of China Ministry of Public Security. This part of the National Standardization Technical Committee for fire protection material Technical Committee (SAC/TC113/SC7) centralized. This section is drafted.

1 Scope

This section GB/T 25206 specifies the test methods used to evaluate the combustion properties of the composite sandwich construction body. By simulating indoor fire Disaster conditions in the building at the corner of the room, with a specific flame acts directly on the article to evaluate building composite sandwich panels or inside the flame pass Broadcast properties. This test is not against the assessment of the performance of refractory products. This section provides composite sandwich panels can be self-supporting and building body frame and other support structure, but applies only to the building wall, ceiling Or the roof structure to be tested.
