EC verification procedures
Article 6
1. The EC verification procedures for the subsystems covered by the TSIs shall be chosen among the modules set out in Annex I, in accordance with the following criteria: (a) whether the module concerned is appropriate to the type of the subsystem; (b) the nature of the risks entailed by the subsystem and the extent to which EC verification corresponds to the type and degree of risk; (c) the need for the manufacturer to have a choice between quality management system and product certification modules set out in Annex I; (d) the need to avoid imposing modules which would be too burdensome in relation to the risks. 2. The TSI(s) shall specify the modules for EC verification to be applied for the subsystems. Where necessary, the TSI(s) may clarify and complement them due to the specificity of the sub system concerned.
