The EN 16842 series specify requirements and test procedures of all around visibility of self-propelled industrial trucks in accordance with ISO/DIS 5053 1 with a sit-on or stand-on operator, without load, and equipped with fork arms or load platform. This part of the EN 16842 series gives the common test requirements for powered industrial truck visibility testing and is intended to be used in conjunction with EN 16842 parts 2 to x. The truck specific requirements in EN 16842 parts 2 to x take precedence over the respective requirements of EN 16842-1. The requirements of the applicable part of EN 16842 take precedence over the requirements of 4.12 of EN 16307-1. The standard does not apply to: trucks with elevating operator position, when the operating position is elevated; rough terrain variable reach trucks within the scope of EN 15830; centre controlled order picking truck (in accordance with 2.17 of ISO/DIS 5053 1); pallet truck end controlled (in accordance with 2.16 of ISO/DIS 5053 1). In addition, the following trucks in normal operation have excellent all round visibility and therefore will not be part of this series of standards: ride on pallet truck; pedestrian controlled pallet trucks.
