In part A of this annex for each directive of the European Parliament and of the Council of 8 May 2000, Directive 2000/14/EC on the approximation of the laws of the Member States relating to the noise emission in the environment by equipment for use outdoors, annex III, article 2, paragraph 1 (annex 1 of these rules) determine the type of equipment — noise emission standards-the noise emission standards General additions sound pressure level measurement the measurement surface enveloping the source and the source sound intensity level. In part B of this annex for each directive of the European Parliament and of the Council of 8 May 2000, Directive 2000/14/EC on the approximation of the laws of the Member States relating to the noise emission in the environment by equipment for use outdoors, annex III, article 2, paragraph 1 (annex 1 of these rules) determine the type of equipment-a recommended basic noise emission standard including-a reference to the basic noise emission standard chosen by A -test area,-the value of the constant K2A-the measurement surface form-the number of the microphone and position-working conditions, including-a reference to the standard, if any,-the requirements relating to equipment installation,-the method to calculate the resulting sound power level if certain tests are performed under differing operating conditions,-additional information. The manufacturer or his authorised representative established in the community by testing the special types of equipment, you can choose A basic noise emission standards and apply to this specific type of equipment, the operating conditions of part B. In the event of a dispute, however, the recommended basic noise emission standard laid down in part B, must be used together with the operating conditions of part B. (A) part. Basic noise emission standard for determining the sound power level of the directive of the European Parliament and of the Council of 8 May 2000, Directive 2000/14/EC on the approximation of the laws of the Member States relating to the noise emission in the environment by equipment for use outdoors, annex III, article 2, paragraph 1 (annex 1 of these rules) defined by equipment for use outdoors, you can typically use basic noise emission standard EN ISO 3744:1995 and EN ISO 3746:1995 subject to the following general enhancements. 1. Measurement uncertainty measurement uncertainties are not taken into account in the conformity assessment procedures in the design phase. 2. the operation of source during test 2.1. Fan speed if the engine of the equipment or its hydraulic system is fitted with fan (s), it (they) must operate during the test. In accordance with one of the following conditions the fan speed has determined and provided by the manufacturer of the equipment and must appear in the test report; This speed being used in further measurements. a) fan drive directly connected to the engine if the fan drive is directly connected to the engine and/or hydraulic equipment (e.g. by belt drive), then it must operate during the test. b) fan drive with different specific speeds if the fan can work at different specific speeds, the test shall be carried out either-with a maximum operating speed, or-the first test with the fan in rest position and the second test at maximum speed. The resulting sound pressure level LPA is calculated by combining both test results with the following equation:

where: LPA .0% is the sound pressure level determined fan to rest position; LPA, 100% is the sound pressure level determined with the fan maximum speed. c) fan drive with continuous variable speed if the fan can work at continuous variable speed, the test shall be carried out in accordance with point 2.1 (b)) or with the fan speed of at least 70% of the maximum speed specified by the manufacturer. 2.2. test of powered equipment free of load for these measurements, the engine and the machine hydraulic system must be warmed up in accordance with the instructions, and safety requirements must be observed. The test is carried out with the equipment in a stationary position when the work equipment or transfer mechanism. This test engine idling with the rated speed corresponding to the engine at least useful power [1]. If the car engine is powered by a generator or from the mains, the engine specified by the manufacturer the power delivered to the frequency stability ± 1 Hz if the machine is equipped with an induction motor, and the supply voltage deviation from the nominal voltage is ± 1%, if the machine is equipped with a switching engine. Supply voltage measured at the non-detachable cable or cord plug or machine input when using a detachable cable. The power of the generator frequency is similar to that obtained from the mains. If the machine is powered, the battery must be fully charged. Speed during the test and the engine net power are stated by the manufacturer of the equipment, and it must be shown in the test report the test. If the equipment is fitted with several engines, they must work simultaneously during the tests. If this is not possible, test each possible combination of engine. 2.3. test of powered equipment free of load for these measurements, the engine (Powertrain plant) and the hydraulic system must be warmed up in accordance with the instructions, and safety requirements must be observed. During the test must not be running any detection device, such as a warning horn or reversing alarm. The machine's speed or the speed shall be recorded during the test, and must appear in the test report. If the equipment is fitted with several engines and/or aggregates they must work simultaneously during the tests. If this is not possible, test each possible engine and/or Assembly. For each type of equipment to be tested under load, specific operating conditions, which, in principle, produce effects and stresses similar to actual work situations. 2.4. Manually-operated equipment test conventional operating conditions of hand for each type of equipment down so that they produce effects and stresses that are similar to the actual working conditions. 3. Surface sound pressure level the surface sound pressure level shall be determined at least three times. If at least two values do not differ by more than 1 dB, further measurements are not required; Otherwise, continue to measure until the two values that do not differ by more than 1 dB.
