7、N/TC 191 “Fixed firefighting systems”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn
8、at the latest by October 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 615:1994. According to the
9、CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania
10、, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 615:2009 (E) 5 1 Scope This European Standard is applicable to fire extinguishing powders for fire classes A, B and C. It specifies, by means of defined test
11、 methods, minimum requirements for the chemical and physical properties and minimum 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 o
12、f fires is given in EN 2 1. NOTE 2 Some countries have national standards for class 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 ed
13、ition of the referenced document (including any amendments) applies. EN 3 (all parts), 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
14、3 Definitions 3.1 (extinguishing) powder extinguishing medium composed of finely 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
15、used to denote special metal fire extinguishing agents and the term “dry chemical 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 be
16、fore the term. The letters used in this European Standard are those defined in EN 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 f
17、ires. 3.2 batch single charge of powder in the processing equipment that has been 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 th
18、e same environmental conditions NOTE Any substantial change in manufacturing process, source of raw materials, or change in environmental conditions may justify identifying the material as a different lot. EN 615:2009 (E) 6 3.4 characteristic value value declared by the supplier for the chemical and
19、 physical properties of the powder 3.5 supplier party e.g. manufacturer, 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 a
20、void any risk of condensation, it is essential that the temperature 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.
21、4.3 Sample containers should not be opened until temperature 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
