26、2013(E)ForewordISO (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 technical committees. Each member body interested in a subject for whi

27、ch 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 with the International Electrotechnical Commission (IEC) on all m

28、atters 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 International Standards adopted by the technical committees are circu

29、lated 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 may be the subject of patent rights. ISO shall not be held responsib

30、le for identifying any or all such patent rights.ISO 14451-2 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 212, Pyrotechnic articles, in collaboration with Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 12, Passive safety crash protection

The typical content of the document shall include the following information: description of th

39、e purpose of the pyrotechnic article; sketch with external dimensions; total mass of the pyrotechnic article; cross section and part list; mass and pyrotechnic composition(s) contained in the article; ISO 2013 All rights reserved 1BS EN ISO 14451-2:2013ISO 14451-2:2013(E) description of intended beh

40、aviour; description of foreseeable behaviour during fire test if applicable; proposed labelling in accordance with ISO 14451-3; safety data sheet/handling instructions, including electrical characteristics (e.g. all-fire current, no-fire current, resistance, etc.) which shall be provided with the py

41、rotechnic article.This shall be verified by visual inspection by the naked eye.4.2 Drop test4.2.1 PurposeThe purpose of this test is to determine whether the pyrotechnic article experiences any detrimental effect when dropped from a specified height and at specified orientations.4.2.2 EquipmentA ste

42、el impact plate of a minimum of 1 m x 1 m with at least 10 mm thickness, resting on a solid floor, with a fixture that supports the pyrotechnic article at the specified height, shall be used.4.2.3 Test conditionsThe drop height shall be 1002+ ,m.The test shall be done with the pyrotechnic article at

43、 ambient temperature.4.2.4 Test procedureMount one pyrotechnic article into the support fixture at the specified height above the impact plate and oriented such that it will fall in one of the six directions indicated in Figure 1. Disarm the trigger device, if included in the pyrotechnic article.Rel

44、ease the pyrotechnic article, allowing it to free fall onto the impact plate. Repeat the test using the same pyrotechnic article oriented to fall in the opposite direction.Repeat the test twice more, once using a second pyrotechnic article and once using a third pyrotechnic article, each time along

45、one of the remaining directions indicated in Figure 1.2 ISO 2013 All rights reservedBS EN ISO 14451-2:2013ISO 14451-2:2013(E)Figure 1 Definition of main axes4.3 Vibration and temperature test4.3.1 PurposeThe purpose of this test is to determine the ability of the pyrotechnic article to withstand vib

46、ration and temperature conditions. The test may be performed simultaneously or sequentially.4.3.2 EquipmentThe equipment shall consist of a vibration table capable of producing the vibration loads as characterized in Figure 2 and a climatic chamber capable of controlling the temperature during the t

47、est in accordance with Figure 3. In case the test is being performed simultaneously the vibration table shall be mounted within the climatic chamber.4.3.3 Test conditionsThe temperature tolerance shall be 2,5 C.4.3.4 Test procedureFix the pyrotechnic article to the vibration table by an appropriate

48、method insuring correct transmission of the vibration load. Apply random vibration in accordance with Table 1 and Figure 2 along each of the three main axes (see Figure 1) of each pyrotechnic article for 24 h.Place the pyrotechnic article in the climatic chamber. The temperature shall be changed in

49、accordance with Figure 3. It may be changed simultaneously with application of the vibration load.
