1 Scope This document specifies the test methods for black powder in pellets, granular form, compressed (press-moulded cylinders with central hollow space) or as a meal for use as propellant, blasting explosive, pyrotechnic or in safety fuses. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13631-2, Explosives for civil uses - High explosives - Part 2: Determination of thermal stability of explosives EN 13631-3, Explosives for civil uses - High explosives - Part 3: Determination of sensitiveness to friction of explosives.
