This document contains a number of defined requirements, some of which have to be demonstrated on the test module, others that are to be certified by the manufacturer. This combination covers not only confirmation of compliance with the standard, which is required to meet the regulatory requirements but also issues of lifetime, quality, maintenance and construction, all of which affect the ability of a sign in its particular application, to meet safety and fitness for purpose. The details in the informative Annexes are provided as useful guidance on the additional aspects relating to VMS for those setting up purchasing contracts for signs or signing systems. The test module ensures that the manufacturer can demonstrate to the purchaser that his requirements have been fulfilled. SIST EN 12966-1:2005+A1:2010
