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.
