Annex C (informative) A-Deviations

This European Standard specifies requirements for the construction, performance and labelling of shell-in-mortars and the corresponding test methods. It is applicable to fireworks which are classified as shell-in-mortars of category 3 in EN 14035-2.It is not applicable to shell-in-mortars containing pyrotechnic composition that includes any of the following substances:arsenic or arsenic compounds;mixtures containing a mass fraction of chlorates greater than 80 percent;mixtures of chlorates with metals;mixtures of chlorates with red phosphorus;mixtures of chlorates with potassium hexacyanoferrate(II);mixtures 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 percent;sulfur with an acidity, expressed as mass fraction of sulfuric acid, greater than 0,002 percent;zirconium with a particle size of less than 40 mm.NOTEIn EN 14035-2, shell-in-mortars are classified as follows: brief description: assembly comprising a shell inside a mortar, from which the shell is designed to be projected; principal effects: projection of the shell and subsequent bursting of the shell case at high altitude, with ejection of any pyrotechnic units producing visual and/or aural effect(s).Schemes for type testing of shell-in-mortars and batch testing of shell-in-mortars are specified in Annex A and Annex B respectively.
