This document specifies requirements for the construction, performance, primary packaging and labelling of serpents and the corresponding test methods. It is applicable to fireworks which are classified as serpents in category 1 in EN 14035-2 and which are contained in a primary pack.It is not applicable to serpents 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 in mass fraction of sulphuric acid, greater than 0,002 %;-zirconium with a particle size of less than 40 mm.NOTEIn EN 14035-2, serpents are classified as follows:- brief description: preformed shape of pyrotechnic composition with or without support;- principal effect: generation of expanded residue.Schemes for type testing of serpents and batch testing of serpents are specified in annex A and annex B respectively.
