DIN EN 16203-2014 Safety of Industrial Trucks – Dynamic tests for verification of lateral stability – Counterbalanced Trucks; English version EN 16203:2014, English translation of DIN EN 16203:2014-11. 4.2 Test set-up and test equipment An appropriate sensor shall be used to measure the travel velocity during the test or, at least, when the forklift truck crosses line 1 (velocity sensor, velocity barrier, etc.). Additional appropriate measures shall be used to verify that the accelerator pedal is fully pressed while driving between line 1 and line 6 or line 7 (e.g. contact sensor under the accelerator pedal). Furthermore, appropriate sensors, a video camera or human observers are necessary to detect whether the test is valid. 4.3 Protective equipment and precautions To enable tests with minimal risk to the driver the truck shall be fitted with: a) an operator restraint system, preferably a seat belt, which maintains the driver safety; b) outrigger type stabilizers as protective equipment to prevent the truck tip-over: 1) The test truck shall be equipped with stabilizers on both sides of the truck. 2) The clearance between the stabilizers and the ground shall be such that tip-over of the vehicle is prevented but a rear wheel lift-off is still possible. For trucks with articulating steer axles, full articulation shall be possible before the stabilizers make contact with the ground. 3) The stabilizers shall be fixed rigidly and securely to the truck. 4) The total mass of the stabilizers shall be less than 10 % of the weight of the unladen truck. 5) The position of the centre of gravity of the truck shall not be lowered by attaching the stabilizers. 4.4 Test Load Test shall be carried out with the unladen truck as defined in Clause 5. 5 Test truck The truck to be tested shall be in a safe and functional state. All equipment attached shall be in accordance to the specification of the manufacturer of the truck. If the test is to be performed on a sample that is representative for a range of trucks, the test shall be carried out on the truck with the most disadvantageous stability values. The fuel tanks of internal combustion engine trucks shall be filled if stability is thereby decreased. All other tanks shall be filled to their correct operating levels, as applicable. The test truck shall be fitted with new tyres (max. 10 % of tread wear) which shall...
