Paragraph 1.3 Test of powered equipment under loadF1

Before measuring the noise emitted by powered equipment under load, manufacturers or their authorised representatives in the Union shall warm up the engine (driving device) and hydraulic system of the equipment up in accordance with the instructions of use, and shall observe safety requirements. The manufacturers or their authorised representatives in the Union shall not operate a signalling device, such as a warning horn or reversing alarm, during the measurement.

Manufacturers or their authorised representatives in the Union shall record the speed or velocity of the equipment during the measurement and state that speed or velocity in the test report.

Where the equipment is fitted with several engines or aggregates, those engines or aggregates shall work simultaneously during the measurements, unless that is not possible, in which case manufactures shall measure noise of each possible combination of engines or aggregates.

Manufacturers or their authorised representatives in the Union shall lay down specific operating conditions for each type of equipment under load. The specific operating conditions shall, as much as possible, produce effects and stresses similar to those encountered under actual working conditions.
