14、ering Standards Committee. BS 873 was first published in 1939 in response to a request from the Association of Road Traffic Sign Makers, and was revised in 1959 and 1970. As a result of subsequent experience and the advent of new materials and methods of construction, it has been further revised to
15、bring it up-to-date. This revision includes a change to metric units, in line with the national policy of metrication. The advent of totally illuminated bollards (plastics bollards) has been taken into account. The opportunity has been taken to specify one luminance range for all areas and to simpli
16、fy the impact test. The Committee has re-considered the need for requirements for resistance to abrasion and has concluded that, while perhaps desirable, it is not practicable to establish suitable conditions of test bearing in mind the wide variety of finishes available within the specification. Th
17、e specification of particular processes and materials in this standard is not intended to pre-empt the development of other processes or materials. The standard may be revised in the future to take account of any suitable developments that occur. The tests specified in this standard necessitate a ro
18、utine sampling procedure. Such procedure should be agreed between the purchaser and the manufacturer at the time of ordering, and in this connection attention is drawn to BS 2635. In references to BS 4533-1, the word “luminaire” should be read as “bollard”. This standard is being revised in a new se
19、ries of Parts. The present is the first Part to be published in this new series. Other Parts will deal with miscellaneous traffic signs, road studs, internally and externally illuminated signs, retro-reflective and non-retro-reflective signs and posts and fittings. A British Standard does not purpor
20、t to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cov
