1 Scope This standard specifies a method of test for determining the non-combustibility performance, under specified conditions, of homogeneous building products and substantial components of non-homogeneous building products. Information on the precision of the test method is given in Annex A. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of these documents is applicable. For undated references, the latest edition of the normative document is applicable to this standard. GB/T 16839.2-1997 "Thermocouples-Part 2: Tolerances" (idt IEC 60584-2:1982) ISO 13943 "Fire Safety-Vocabulary" EN 13238 "Reaction to Fire Tests for Budding Products-Conditioning Procedures and General Rules for Selection of Substrates" 3 Terms and Definitions For the purpose of this standard, the terms and definitions given in ISO 13943, together with the following, apply: 3.1 Building product Building material, element or component about which information is required, including installation, construction and composition. 3.2 Building material A single basic substance or uniformly dispersed mixture of substances e.g. metal, stone, timber, concrete, mineral wool with uniformly dispersed binder, polymers. 3.3 Loose fill material Material without any physical shape. 3.4 Homogeneous product A product, consisting of a single material, having uniform density and composition throughout the product. 3.5 Non-homogeneous product A product that does not satisfy the requirements of a homogeneous product. It is a product composed of more than one component, substantial and/or non-substantial. 3.6 Substantial component A material that constitutes a significant part of a non-homogeneous product. A layer with a mass/unit area ≥1.0kg/m2 or a thickness ≥1.0mm is considered to be a substantial component. 4 Test Apparatus 4.1 General 4.1.1 The test apparatus shall be capable of creating the conditions specified in 7.1. A typical design of furnace is given in Annex B; other designs of furnace may be used. 4.1.2 All dimensions given in the description of the test apparatus are nominal values, unless tolerances are specified. 4.1.3 The apparatus shall consist of a furnace comprising essentially a refractory tube surrounded by a heating coil and enclosed in an insulated surround. A cone-shaped airflow stabilizer shall be attached to the base of the furnace and a draught shield to its top. 4.1.4 The furnace shall be mounted on a stand and shall be equipped with a specimen holder and a device for inserting the specimen-holder into the furnace tube. 4.1.5 Thermocouples, as specified in 4.4, shall be provided for measuring the furnace temperature and the furnace wall temperature. Annex C gives details of additional thermocouples to be used if the specimen surface temperature and the specimen centre temperature are required. The thermal sensor, as specified in 4.5, shall be provided for measuring the furnace temperature along its central axis.
