Introduction
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
This noise-test code specifies all the information necessary to carry out efficiently and under
standardized conditions the determination, declaration and verification of the noise-emission
characteristics of trucks.
Noise-emission characteristics include the emission sound pressure levels at workstations and the
sound power level.
The determination of those values is necessary for:
— manufacturers to declare the noise emitted from their machines;
— the design stage and to ensure conformity of production.
The test codes here described are taken from the Working Group 7 position paper – Summary of
information gathered to contribute to the Article 20 report (version NOISE/13/01/2 rev.1 adopted June
2013).
The use of these test codes ensures that the tests are conducted and the data is processed in a reliable
and reproducible manner.
Test codes defines the limits accuracies and are conducted in engineering methods (grade 2).
Main sources of noise in trucks are:
— internal combustion engine;
— hydraulic components (cylinders, pump…);
— motor fans;
— control valves;
— exhaust gas emission point;
— transmission components.

prEN 1459-7:2017 (E)
Typical measures to reduce noise at design stage are:
— selection of low noise components;
— use of exhaust silencers for engine.
Typical measures to reduce noise by protective measures are:
— the use of sound insulating covers and enclosures around noisy components;
— the use of a sound insulating enclosed cab;
— place the noisy components away from the normal operator’s position.
Other measures of identical or better efficiency can be used.

For the purposes of this document, the terms and definitions given in EN ISO 3744:2010,
EN ISO 4871:2009 and EN ISO 11201:2010 apply.

4 Safety requirements
4.1 Instrumentation
4.1.1 General
The instrumentation system, including the microphones, cables and windscreen, if used, shall meet the
requirements of IEC 61672-1:2002, class 1, and the filters shall meet the requirements of
IEC 61260:1995, class 1.
4.1.2 Calibration
Unless national regulations dictate otherwise, it is recommended that the sound calibrator should be
calibrated at intervals not exceeding 1 year, the reference sound source should be calibrated at
intervals not exceeding 2 years, the compliance of the instrumentation system with the requirements of
IEC 61672-1 should be verified at intervals not exceeding 2 years, and the compliance of the filter set
with the requirements of IEC 61260 should be verified at intervals not exceeding 2 years.
4.2 Test environment
4.2.1 General
Humidity, air temperature, barometric pressure, vibration and stray magnetic fields shall be within the
limits specified by the manufacturer of the instrumentation.
4.2.2 Test site and environmental correction, K
2A
The test area bordered by the vertical projection of the microphones to the ground shall consist of
concrete or non-porous asphalt.
The environmental correction, K , shall be determined according to Annex A of EN ISO 3744:2010
2A
(absolute comparison test), to account for deviations of the test environment from the ideal condition.
Measurements in accordance with this European Standard are only valid where K ≤ 4 dB (accuracy
2A
grade 2).
For test-site measurement ground surfaces consisting of a hard reflecting plane, and having negligible
sound-reflecting obstacles within a distance from the source equal to three times the measurement
hemisphere radius, it may be assumed that the absolute value of environmental correction, K , is less
2A
than or equal to 0.5 dB, and can therefore be disregarded. In this case, K shall be equal to 0 dB.
