Introduction
This European Standard is a type C standard as defined in EN 292-1. This standard has been prepared to be a
harmonized standard to provide one means of conforming to the essential safety requirements of the Machinery
Directive and associated EFTA regulations.
The extent to which hazards are covered is indicated in the scope of this standard. In addition, industrial trucks
should comply as appropriate with EN 292-1 for hazards which are not covered by this standard.
General standards for the determination of the noise emissions at the operator's position and of the sound power
levels of machines already exist. However and because of specific applications these existing standards cannot be
applied directly to industrial trucks. Therefore it was necessary to prepare this standard. The basic standards EN
ISO 3744 : 1995 and EN ISO 11201 : 1995 have been taken into account.
A further aim of this European standard is, despite the variety of industrial trucks, to obtain representative and
comparable information on the noise emissions of this category of equipment. It should be possible to determine
and verify this information. This requires definition of conditions of operation and typical time proportions.
The IDLE condition of the industrial truck is included because it is representative of those conditions in which the
industrial truck has low noise emission, for instance, when lowering, tilting, load handling, slow manoeuvring as well
as waiting between tasks.
The determination of sound power levels with the commonly used enveloping measurement surface method, with
six or more microphone positions in the DRIVE condition, is only possible with considerable technical difficulty. The
proposed method with four microphone positions has been shown, following extensive comparisons, to produce
final results that deviated only minimally in numerous comparisons, so that the intended purpose was achieved.
The test results, however, are not applicable to the determination of exposure to noise at the operator's position in
accordance with EU Directive 86/188/EEC.
1 Scope
This noise measurement standard gives methods for determining the sound pressure level at the operator's
position and the sound power level of industrial and rough terrain trucks.
This European standard is a type test applicable to all industrial trucks listed in table A1.
The test results obtained in accordance with this standard are also applicable to the evaluation of the hazard
generated by noise from industrial trucks.

normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
