13、11:00 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 21367:2007(E) iv ISO 2007 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Intern
14、ational Standards is normally carried out through ISO technical 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
15、 ISO, also take part in the work. ISO collaborates closely with 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
16、 committees is to prepare International Standards. Draft International 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
17、the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

19、s reserved 1 Plastics Reaction to fire Test method for flame spread and combustion product release from vertically oriented specimens WARNING Avoidance of misleading inferences This standard method of test should be used solely to measure and describe the properties of materials, products or systems
20、 in response to heat or flame under controlled laboratory conditions, and should not be considered or used by itself for describing or appraising the fire hazard of materials, products or systems under actual fire conditions or as the sole source on which regulations pertaining to smoke production c
21、an be based. WARNING Avoidance of danger to test operators So that suitable precautions to safeguard health are taken, the attention of all concerned in fire tests is drawn to the fact that harmful gases are evolved in combustion of test specimens. Attention is drawn to the hazards arising from the
22、hot radiator, and the use of a mains-voltage electricity supply. 1 Scope This International Standard specifies a test method for plastics for the determination of the heat release rate, ignitability, surface spread of a flame, falling droplets/particles and smoke production using a “medium” scale sp
23、ecimen that simulates the early development stage of the fire. This test method can be used as a screening test for intermediate scale and large scale tests in addition to its use in factory production control, research and product development. This test method provides data that is suitable for com
24、paring reaction-to-fire performance of many materials, products, composites or assemblies under end use application conditions. The results of this test method are limited to specimens with heat release rates of less than 10 kW. WARNING Specimens having the dimensions specified in this International
