Foreword
This European Standard has been prepared by the Technical Committee CENELEC TC 61F, Safety of
hand-held and transportable motor-operated electric tools. The text of the draft was submitted to the
Unique Acceptance Procedure and was approved by CENELEC as EN 50144-2-16 on 2003-02-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
 at national level by publication of an identical
 national standard or by endorsement (dop) 2004-02-01
- latest date by which the national standards conflicting
 with the EN have to be withdrawn (dow) 2006-02-01
This standard is divided into two parts
Part 1 General requirements which are common to most hand-held electric motor-operated tools
(for the purpose of this standard referred to simply as tools)
Part 2 Requirements for particular types of tools which either supplement or modify the
requirements given in Part 1 to account for the particular hazards and characteristics of
these specific tools.
This European Standard has been prepared under a mandate given to CEN/CENELEC by the
European Commission and the European Free Trade Association and supports the essential health
and safety requirements of the Machinery Directive.
Compliance with the relevant clauses of Part 1 together with this Part 2 provides one means of
conforming with the specified essential health and safety requirements of the Directive.
For noise and vibration, this standard covers the requirements for their measurement, the provision of
information arising from these measurements and the provisions of information about the personal
protective equipment required.
Specific requirements for the reduction of the risk arising from noise and vibration through the design
of the tool are not given as this reflects the current state of the art.
CEN/TC 255 has produced standards for non electric tackers (EN 792-13).
Warning: Other requirements arising from other EC Directives can be applicable to the products
falling within the scope of this standard.
This standard follows the overall requirements of EN 292-1 and EN 292-2.
Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101.
NOTE  In this standard the following print types are used:
- requirements proper;
- test specifications;
- explanatory matter.

13 Environmental requirements

This clause of Part 1 is applicable except as follows:

13.1 This subclause is not applicable.

13.2 Replacement

13.2 Noise test code

13.2.1 Sound power level determination

13.2.1.1 General

The sound power level of tackers shall be determined by applying EN ISO 3744.

The sound power level shall be given as A-weighted single event sound power level in dB.

-12
The reference sound power is 1 pW (1 pW = 10 W).

13.2.1.2 Measurement procedure

The measurement surface is a hypothetical cube on which the measurement positions 1 to 9 are
located and which envelops the tacker (see Figure 101).

The measurement surface ends at floor level, which is to be regarded as a sound reflecting surface.
The height of the centre point of the tacker above the ground shall be (1,00 ± 0,10) m. The centre
point is located on the driving axis at half of the height of the tacker.

NOTE Because a tacker is of small size the centre point of a tacker is used instead of the surface.

The measurement distance shall be 1,00 m from the centre point of the tacker (see Figure 101).

i
The location of the nine measurement positions = 1, 2, ., 9 shall be that of Figure 101.

L′
The A-weighted single-event sound pressure level of one driving process shall be measured
pA,1s
five times at each measurement position i. The arithmetic mean of the five values shall be determined
for each measurement position and is denoted L′ (with i = 1, 2,…,9).

13.2.1.3 Calculation of the A-weighted single-event sound power level
