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 µm.
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.
