EN 14035-35:2004 (E) 6 1 Scope This document specifies requirements for the construction, performance, primary packaging and labelling of throwdowns an
32、d the corresponding test methods. It is applicable to fireworks which are classified as throwdowns in category 1 in EN 14035-2 which contain pyrotechnic report composition that is silver fulminate and which are contained in a primary pack. It is not applicable to throwdowns containing pyrotechnic co
33、mposition that includes any of the following substances: arsenic or arsenic compounds; mixtures containing a mass fraction of chlorates greater than 80 %; mixtures of chlorates with metals; mixtures of chlorates with red phosphorus; mixtures of chlorates with potassium hexacyanoferrate(II); mixtures
34、 of chlorates with sulfur; mixtures of chlorates with sulfides; lead or lead compounds; mercury compounds; white phosphorus; picrates or picric acid; potassium chlorate with a mass fraction of bromates greater than 0,15 %; sulfur with an acidity, expressed as mass fraction of sulfuric acid, greater
35、than 0,002 %; zirconium with a particle size of less than 40 m. NOTE In EN 14035-2, throwdowns are classified as follows: brief description: impact-sensitive pyrotechnic composition and grains of inert material wrapped in tissue paper or foil; principal effect: report, when thrown down onto the grou
36、nd. Schemes for type testing of throwdowns and batch testing of throwdowns are specified in annex A and annex B respectively.

41、n saw dust. Conformity to this requirement shall be verified by visual examination. 4.2 Materials of firework case The body of the firework case shall be made of tissue paper or foil. Conformity to this requirement shall be verified by visual examination. 4.3 Integrity of firework case There shall b
42、e no holes or splits in the body of the firework case and it shall retain the contents. Conformity to these requirements shall be verified by visual examination. 4.4 Net explosive content When determined in accordance with 8.3, a throwdown shall have a net explosive content of not more than 2,5 mg.
43、EN 14035-35:2004 (E) 8 4.5 Pyrotechnic composition When determined in accordance with 8.3, the report composition shall only be silver fulminate. 5 Performance 5.1 Principal effect When tested in accordance with 8.2, the principal effect of the throwdown, as given in EN 14035-2, shall be a single re
44、port. 5.2 Protection of throwdowns When tested in accordance with 8.1, the throwdown shall not explode and when tested subsequently in accordance with 8.2 it shall produce a single report. 5.3 Number of reports When tested in accordance with 8.2, the throwdown shall not produce more than one report.
