INTRODUCTION
This amendment introduces a description of the intensimetric method for the determination of
sound power levels of range hoods in addition to the other methods described in the standard,
for the use of which the text of IEC 60704-2-13 remains unchanged. According to the method
described here, the sound power level is obtained by measuring the component of sound
intensity normal to a measurement surface that surrounds the range hood.

Add, after the listing for Annex AA, the title of the new bibliography as follows:

1 Scope and object
1.1.1 General
Add, to the existing text, the following new paragraph:
Intensimetric method for the determination of sound power levels shall not be used for the
purpose of verification.
60704-2-13 Amend. 1  IEC:2005(E) – 3 –
1.1.2 Types of noise
Replace the existing text of the addition by the following new text:
Addition:
The method is applicable to any source for which a physically stationary measurement
surface can be defined, and on which the noise generated by the source is stationary in time
(as defined in Clause 3), therefore it is not suitable for sources of impulsive noise consisting
of short duration noise bursts. This method is not suitable if the source under test has
significant noise over 6,3 kHz in one-third-octave band centre frequencies and over 4 kHz in
one-octave band centre frequencies.
1.1.3 Size of the source
Replace the existing text of the replacement by the following new text:
Replacement:
The size of the noise source is unrestricted. The extent of the source is defined by the choice
of the measurement surface.
Page 13
Add the following subclause:
1.3 Measurement uncertainty
Replacement:
The uncertainty in the determination of the sound power level of a noise source is related:
– to the nature of the sound field of the source;
– to the nature of the extraneous sound field;
– to the absorption of the source under test;
– to the type of intensity-field sampling and measurement procedure employed.
The normal range for A-weighted data is covered by the one-octave bands from 63 Hz to
4 kHz, and the one-third-octave bands from 50 Hz to 6,3 kHz. The estimated values of
standard deviations of sound power levels, determined according to this standard for both the
discrete points method and the scanning method are as indicated in Table 101.

4 Measurement methods and acoustical environments
Add the following subclause:
4.1 General
Replacement:
The total noise emitted by machinery or equipment, and radiated in all directions to the space
surrounding the machine, can be characterized by the sound power of the machine. The
sound power of a machine is essentially independent of the environment in which the machine
is installed.
Therefore, the concept of sound power level has been chosen for expressing the noise
emission of appliances for household and similar purposes.
The preferred noise emission quantity is the A-weighted sound power level, in decibels (re.
1 pW).
According to this standard, one method is used, the direct method as described in 4.2 below.
4.2 Direct method
Replace the existing text of the addition with the following new text:

Addition:
The measurement can be performed according to two intensimetric methods, the "discrete
points method" and the "scanning method", as described below.
4.2.101 Discrete points method
Define, as the measurement surface, a parallelepiped-shaped surface around the range hood;
then divide it in partial areas (segment) so as to obtain a grid. The dimension of the
parallelepiped depends on the dimension of the
