Scope

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.
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.
