18、BS EN ISO 1182:2010EN ISO 1182:2010 (E)iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO techni

19、cal committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely w

20、ith the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Int

21、ernational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document m

22、ay be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1182 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation and growth. This fifth edition cancels and replaces the fourth edition (ISO 118

23、2:2002), which has been technically revised. BS EN ISO 1182:2010EN ISO 1182:2010 (E) ISO 2010 All rights reserved vIntroduction This fire test has been developed for use by those responsible for the selection of construction products which, whilst not completely inert, produce only a very limited am

24、ount of heat and flame when exposed to temperatures of approximately 750 C. The limitation of the field of application to testing homogeneous products and substantial components of non-homogeneous products was introduced because of problems in defining specifications for the specimens. The design of

25、 the specimen of non-homogeneous products strongly influences the test results, which is the reason non-homogeneous products cannot be tested to this International Standard.

26、d 1Reaction to fire tests for products Non-combustibility test SAFETY PRECAUTIONS The attention of all persons concerned with managing and carrying out this test is drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic, harmful smoke and gases can be evolved

27、 during the test. Operational hazards can also arise during the testing of specimens and the disposal of test residues. An assessment of all potential hazards and risks to health should be made and safety precautions should be identified and provided. Written safety instructions should be issued. Ap

28、propriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. 1 Scope This International Standard specifies a method of test for determining the non-combustibility performance, under specified conditions, of ho

29、mogeneous products and substantial components of non-homogeneous products. Information on the precision of the test method is given in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cit

30、ed applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

36、to locate the ends of the furnace tube. The annular space between the tubes shall be filled with a suitable insulating material. NOTE 1 An example of a typical furnace tube design is given in B.2. An open-ended cone-shaped airflow stabilizer shall be attached to the underside of the furnace. The sta

37、bilizer shall be 500 mm in length, and reduce uniformly from 75 1 mm internal diameter at the top to 10 0,5 mm at the bottom.

38、ght fit, with a smooth finish internally. The upper half of the stabilizer shall be insulated externally with a suitable insulating material. NOTE 2 An example of suitable insulating material is given in B.3. 4.2.2 Draught shield, made of the same material as the stabilizer cone, and provided at the

39、 top of the furnace. It shall be 50 mm high and have an internal diameter of (75 1) mm.
