ÖNORM EN 14035-31

This European Standard specifies requirements for the construction, performance and labelling of shell-inmortars and the corresponding test methods. It is applicable to fireworks which are classified as shell-inmortars 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 %; 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 %; sulfur with an acidity, expressed as mass fraction of sulfuric acid, greater than 0,002 %; zirconium with a particle size of less than 40 m. NOTE In 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.
