It specifies, by means of defined test methods, minimum requirements for the chemical and physical properties and mini
28、mum extinguishing capabilities. Requirements are also specified for the information and data to be given by the supplier. This European Standard is not applicable to powders for class D fires. NOTE 1 The classification of fires is given in EN 2 1. NOTE 2 Some countries have national standards for cl
29、ass D powders. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 3 (all p
30、arts), Portable fire extinguishers EN ISO 4788, Laboratory glassware - Graduated measuring cylinders (ISO 4788:2005) ISO 3310-1, Test sieves - Technical requirements and testing - Part 1: Test sieves of metal wire cloth 3 Definitions 3.1 (extinguishing) powder extinguishing medium composed of finely
31、 divided solid chemical products consisting of one or more principal components which are combined with additives to improve its characteristics NOTE 1 In North America and some other countries, the term “dry powder“ is used to denote special metal fire extinguishing agents and the term “dry chemica
32、l extinguishing agent“ is used to denote the extinguishing medium specified in the European Standard. NOTE 2 When it is useful to indicate the class of fire for which a powder is designed, capital letters may be added before the term. The letters used in this European Standard are those defined in E
33、N 2 1. EXAMPLE BC powder is designed to extinguish class B (liquids or liquefiable solids) and class C (gases) fires; ABC powder is designed to extinguish class A (solids which form glowing embers), class B and class C fires. 3.2 batch single charge of powder in the processing equipment that has bee
34、n made homogeneous by subjection to the same unit and physical processing 3.3 lot one or more batches, but not more than 25 t of powder, manufactured to the same formulation by the same manufacturing process and under the same environmental conditions NOTE Any substantial change in manufacturing pro
35、cess, source of raw materials, or change in environmental conditions may justify identifying the material as a different lot. DIN EN 615:2009-08 EN 615:2009 (E) 6 3.4 characteristic value value declared by the supplier for the chemical and physical properties of the powder 3.5 supplier party e.g. ma
36、nufacturer, distributor, importer, responsible for the powder and able to ensure that quality assurance is exercised 4 Sampling 4.1 Samples for testing shall be taken using a method which will provide a representative sample. In order to avoid any risk of condensation, it is essential that the tempe
37、rature of the powder in its original container is not lower than the ambient air temperature when the sample is being taken. 4.2 Samples shall be stored in individual, clean, dry, airtight, non-reactive and suitably identified containers. 4.3 Sample containers should not be opened until temperature
38、equilibrium with the laboratory has been reached. NOTE 1 One suitable method of sampling is suggested in Annex F. NOTE 2 Unless otherwise specified, all tests on samples are carried out at (20 5) C. 5 Bulk density The bulk density shall be within 0,07 g/ml of the characteristic value when tested in
39、accordance with Annex A. 6 Sieve analysis The cumulative percentages oversize on the 40 m sieve and on the 63 m sieve shall not differ from the characteristic values by more than 8 % of the total mass of the sample, and the cumulative percentage oversize on the 125 m sieve shall not differ from the
40、characteristic value by more than 5 % of the total mass of the sample when the powder is tested in accordance with one of the methods of Annex B. NOTE 1 Annex G describes one of the methods of analysis technique which gives more detailed information on particle size. NOTE 2 The two methods described
41、 in Annex B may give differing results. The method used should therefore be given in the results. 7 Chemical content Characteristic values for chemical content shall be expressed as percentages (m/m) of the total content. The characteristic values for chemical content shall include all constituents
42、present in the powder at a concentration representing 10 % or more of the total content. The sum of the characteristic values for chemical content shall be 90 % or more of the total content. Each constituent given a characteristic value shall be identified by its chemical name, or as the reaction pr
43、oduct of a chemical process between reactants identified by their chemical names. In the latter case, the chemical process shall be specified, for example by reference to a published patent. DIN EN 615:2009-08 EN 615:2009 (E) 7 The content of a declared constituent shall be as follows: a) within 1,0
44、 % of the total chemical content for constituents of characteristic value more than 10 % but not more than 15 %; b) within 1,5 % of the total chemical content for constituents of characteristic value more than 15 % but not more than 25 %; c) within 2,0 % of the total chemical content for constituent
45、s of characteristic value more than 25 % but not more than 65 %; d) within 3,0 % of the total chemical content for constituents of characteristic value more than 65 % and above. NOTE 1 For example, a constituent with a characteristic value of 20 % has tolerance limits of 18,5 % and 21,5 % and a cons
46、tituent with a characteristic value of 80 % has tolerance limits of 77 % and 83 %. NOTE 2 WARNING It is important that under normal conditions of use the various materials and additives used to produce powders be generally recognized as being non-toxic to humans. In some countries there may be a leg
47、al obligation to disclose to designated authorities the complete chemical content, and any proposed changes of chemical content, with documented details of non-toxicity. NOTE 3 The compatibility of the powder with foam (see Annex H) depends on chemical content. The test described in Annex K may allo
48、w a determination of foam/powder compatibility to be made. NOTE 4 WARNING The mixing of different types of powder (ABC and BC) may result in caking, and the production of gas which will increase pressure in the container to an unsafe level. Such increases in pressure have been known to cause contain
49、ers to rupture, and to cause bodily injury and damage. NOTE 5 WARNING Recovered powder may have been previously contaminated, and may have absorbed moisture. If it is then recycled, the powder may eventually become lumpy, and interrupt the flow of powder when used on a fire. 8 Fire test performance 8.1 General A 6 kg or 9 kg stored pressure or cartridge extinguisher may be used to test conformity to this clause, but the same model of extinguisher shall be used for class A rating (if applicable), class B rating and to test
