HD 638 S1, Road traffic signal systems 3 Terms and definitions For the purposes of this document, the terms and definitions given in CIE 15.2:1986 and CIE 17.4:1987 and the following apply. NOTE When reading this document for the first time, particular attention should be paid to Annex B.
3.1 backing-board surround to the VMS, used depending on local circumstances, providing improved visibility of the VMS by means of broadening its size and by providing suitable visible contrast with the VMS background 3.2 cantilever support support system with a single post and a cantilever arm supporting VMS(s) mounted over the traffic lane(s) 3.3 control device equipment used to execute a change of message other than by purely manual means

3.13.1 matrix grid whose intersections hold the centre of the elements used in a VMS. A matrix may cover the whole display surface or part of it. Axes X and Y of the grid may or may not be orthogonal 3.13.2 irregular matrix spacing of intersections on either X or Y or both axes is not constant

This is the only occasion where tests may be carried out on material and not the whole test module. 7 Visual performance 7.1 Classification The manufacturer shall declare the relevant class designations for his products. This shall be in accordance with those photometric parameter classes listed in Table 1. Table 1 — Class designation of the photometric parameters of the VMS Photometric parameter Class designation Remarks Colour C1, C2 C2 is the more restrictive L1, L2, L3, L3(*) L3 has the highest luminance (*) for specific situations

In addition to the insulation of electrical parts in all circuits, the design shall conform to the degrees of pollution in accordance with EN 60664-1. For the purpose of evaluating creepage distances and clearances the following four classes have been established. - Pollution degree 1: Class D1 No pollution or only dry, non-conductive pollution occurs. The pollution has no influence. - Pollution degree 2: Class D2 Only non-conductive pollution occurs except that occasionally a temporary conductivity caused by condensation is to be expected. - Pollution degree 3: Class D3. Conductive pollution occurs or dry non-conductive pollution occurs which becomes conductive due to condensation which is to be expected. - Pollution degree 4: Class D4.

EN 12767. If passive safety is not declared, the VMS supports shall be considered as Class 0 of EN 12767. 8.3.4 Impact resistance The test modules shall be capable of withstanding impact, and shall be tested in accordance with 9.2.3, Table 13. After the test the test module front panel or parts of it shall show no damage and the test module shall continue to meet all the requirements of the standard. 8.3.5 Vibration resistance The test modules shall be capable of withstanding vibration, and shall be tested in accordance with 9.2.3, Table 14.

This shall be tested in accordance with 9.2.4. 8.4.1.7 Temporary overvoltage When protection for temporary (not transient) overvoltage is incorporated, the operating voltage range of the protective device shall be stated. This shall be tested in accordance with 9.2.2 Table 11. 8.4.2 Electrical safety The test module shall conform to electrical safety requirements of HD 60364-4-443 and HD 638 as applicable. 8.5 Electromagnetic compatibility 8.5.1 Electromagnetic emission For all types of environment the test module shall conform to EN 50293. 8.5.2 Electromagnetic immunity For all types of environment the test module shall conform to EN 50293. 9 Test methods 9.1 Test modules 9.1.1 General
NOTE In order to allow for future developments in technology and sign design, the standard uses performance requirements which are not dependent on technology and which can be demonstrated on a test module. 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.

The shaded squares are equivalent element areas and form the optical test area The spacing between the centres of the elements shall be measured for the test modules, which meet the test requirements and shall be reported as the “element spacing”. The element spacing of the actual VMS shall be within ± 10 % of the element spacing measured on the test module. 9.1.3 Function test 9.1.3.1 General The function test is based on alternate activation/deactivation of all the elements, which is the cyclic change of all elements from one state to another.
