1 Scope
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 17.
The EN 16842 series specify requirements and test procedures of all around visibility of self-propelled industrial trucks (herein after referred to as trucks) in accordance with ISO 5053-1 with a sit-on or stand-on operator, without load, and equipped with fork arms or load platform.
The truck specific requirements in EN 16842 parts 2 to 17 supplement or modify the corresponding clauses of this part EN 16842-1 and provide the relevant requirements for the specific truck.
The visibility test requirements of the applicable part of EN 16842 for each truck type are used to fulfil the visibility requirements of the EN 16307 series.
This European Standard does not apply to:
一industrial, rough terrain variable reach or rough terrain masted lorry mounted trucks;
一trucks with elevating operator position, when the operating position is elevated above 500 mm;
-rough terrain variable reach trucks – within the scope of EN 15830;
一centre controlled order picking trucks (in accordance with 3.16 of ISO 5053-1:2015);
一pallet truck end controlled (in accordance with 3.15 of ISO 5053-1:2015).
NOTE 1 The following trucks in normal operation have excellent 360° visibility and therefore will not be part of this series of standards:
一ride on pallet truck;
一pedestrian controlled pallet truck.
NOTE 2 For trucks equipped with attachments (e.g. clamp), see Clause 9 “Information for use”.
4 Truck configuration
4.1 General
The test shall be conducted with an unladen truck on a level, horizontal floor. The truck shall be equipped with a load platform or two fork arms of a length up to dimension“A” as indicated in the appropriate part of the EN 16842 series, centrally spaced at an outside distance within the normal fork adjustment range of the specific configuration tested. The test method of this standard applies to all configurations, including additional tests for various types of masts, external fuel tanks, counterweights, cabs, etc. that adversely affect visibility. Where a configuration has no adverse effect on visibility the test may not need to be repeated. The test shall be valid for the determined configurations as specified in the test report inClause 8. Information about mast tilt and/or retractable mast position can be found in the applicable truck specific part in this series.
