BS EN 16261-2:2013EN 16261-2:2013 (E) 6 4 Pyrotechnic composition No limits are given for the net explosive content (NEC)1)of Category 4 articles in this standard. 5

30、 Construction (type test and batch test) When tested in accordance with 6.1 and 6.2 of EN 16261-3:2012, the article dimensions and gross mass shall be in accordance with the manufacturers declaration (including tolerances). The orientation of mortars shall be verified by inspection according to 6.3

31、of EN 16261-3:2012, during type test. When the orientation of mortars in combinations is not visible, the maximum firing angle shall be displayed on the label and verified by visual inspection according to 6.7 of EN 16261-3:2012. 6 Means of ignition 6.1 Identification (type test and batch test) The

32、means of ignition shall be clearly visible or shall be indicated by labelling or instructions where applicable. Conformity to this requirement shall be verified by visual examination according to 6.7 of EN 16261-3:2012. 6.2 Protection (type test and batch test) Where appropriate, the means of igniti

33、on shall be protected to avoid accidental ignition of the fireworks. Conformity to this requirement shall be verified by visual examination according to 6.7 of EN 16261-3:2012. 7 Performance 7.1 Properties to be checked before functioning tests 7.1.1 Loose pyrotechnic composition after mechanical co

34、nditioning (type test) When tested in accordance with 6.8 of EN 16261-3:2012, the loose pyrotechnic composition found outside the article after mechanical conditioning shall be weighed. The mass of the whole loose material shall comply with manufacturers specifications (if any) and the mass of loose

35、 pyrotechnic composition shall not exceed 3 % of the NEC and not more than 1 g for each item tested. If the pyrotechnic composition cannot be separated from the loose material, the same limits shall apply to the whole loose material. 1) The NEC has an influence (directly or indirectly) on the safety

36、 distances. For Category 4 fireworks, it is agreed that no fixed minimum safety distances are defined, contrary to Category 1, 2 and 3 fireworks. The safe use of Category 4 fireworks is one of the major responsibilities of the person with specialist knowledge who should determine the minimum safety

37、distance by using the information given in prEN 16261-4:2011, Clause 4. BS EN 16261-2:2013EN 16261-2:2013 (E) 7 7.1.2 Integrity (type test and batch test) 7.1.2.1 General requirements There shall be no holes, splits, dents or bulges either in the body of the firework case or in the end closures, exc

38、ept those technically necessary for the correct functioning of the firework. If the end closures are separate components, they shall be in place. There shall be no pyrotechnic leakage of the article to be tested when it is received for testing. Conformity to these requirements shall be verified by v

39、isual examination according to 6.7 of EN 16261-3:2012. 7.1.2.2 Specific requirements For combinations: each individual element shall be securely attached to the other elements or to the framework. Attachment by the transmitting fuse(s) alone shall be allowed if it is sufficient to keep the elements

40、joined together during normal handling. Conformity to above requirements shall be checked by visual examination according to 6.7 of EN 16261-3:2012. 7.2 Properties to be checked during functioning tests 7.2.1 Principal effects (type test and batch test) When tested in accordance with 6.10 of EN 1626

41、1-3:2012, the principal effects of each firework shall conform to those specified by the manufacturer or importer as described in EN 16261-1. 7.2.2 Functioning (type test and batch test) For type test only, functioning test in accordance with 6.10 of EN 16261-3:2012, shall be performed in as receive

42、d conditions and, after mechanical and thermal conditions in accordance with 6.8 and 6.9 of EN 16261-3:2012. For type test and batch test, when tested in accordance with 6.10 of EN 16261-3:2012, the article shall function as intended and shall not function in an erratic and unforeseeable manner. 7.2

43、.3 Stability during functioning (type test and batch test) When used according to the instructions for use, the article shall remain in its initial position and maintain its integrity whilst functioning, if applicable. Conformity to these requirements shall be checked by the method described in 6.10

44、 of EN 16261-3:2012. 7.2.4 Performance parameters (type test and batch test) The mandatory parameters listed in Annex A shall be measured and recorded according to 6.4, 6.5, 6.10.3 and 6.10.4 of EN 16261-3:2012 (if applicable). During type tests, all test results shall be within a tolerance of 20 %

45、of the measured average, except as otherwise justified by the manufacturers. The measured average value shall be displayed on the label. This value may be rounded. Tolerances regarding performance parameters are only applicable to articles in as received condition. During batch tests, all test resul

46、ts shall be within a tolerance of null 30 % from the value which is displayed on the label. These tolerances are not applicable for sound pressure. BS EN 16261-2:2013EN 16261-2:2013 (E) 8 7.2.5 Sound pressure level (type test and batch test) For articles which have report, explosion, and/or whistlin

47、g effects as part of their performance, the sound pressure level shall be measured and recorded at a predefined distance from the firing point according to 6.5 of EN 16261-3:2012. The maximum measured value or a higher value if specified by the manufacturer shall be displayed on label. During batch

48、test, the measured value shall not exceed the displayed value. 7.2.6 Extinguishing of flames (type test) When tested in accordance with 6.6 of EN 16261-3:2012, the existence of flames observed more than 2 min after the end of functioning of the article shall be displayed on the label or in the instr

49、uctions for use. Conformity to this requirement shall be tested by visual examination according to 6.7 of EN 16261-3:2012. 7.2.7 Projected debris (type test and batch test) If the type test has shown projection of debris, the design of the firework shall be examined in accordance with 6.2 of EN 16261-3:2012 to establish whether the debris is a result of the design or malfunction of the article. If the debris is the result of design, the instructions for use shall be checked according to 6.7 of EN 16261-3:2012,
