Renumber existing Notes 6 and 7 as Notes 5 and 6.
Replace Subclause 32.102 by the following new subclauses:

32.101.1 The irradiance is measured with the measuring instrument being placed so that the
highest effective irradiance is recorded at positions which model the human body as follows:
– for appliances which expose persons from below, the measuring instrument is placed on
the surface the person lies on;
– for appliances that are arranged over a person, the measuring instrument is placed on the
surface of a half-cylinder with a radius of 300 mm in case of full body exposure (position 2
in Figure 101) or of 150 mm in case of facial exposure (position 1 in Figure 101). The half-
cylinder is placed directly on the surface the person lays on and is aligned along the
centre line of this surface. The half-cylinder for the facial measurement is placed on a
50 mm base that is itself placed directly on the surface the person lays on and is aligned
along the centre line of this surface. In the transition area between head and body,
measurements are conducted in position 1 and position 2 and the higher effective
irradiance is recorded;
– for appliances having upper and lower radiating surfaces, each part is measured
separately while the other part is covered. If the distance between two radiating surfaces

© IEC 2015
is less than 300 mm or 200 mm for a facial measurement, the measurement is made at the

surface of the upper panel;
– for appliances exposing an upright standing person from all sides, the measuring

instrument is placed on the surface of a cylinder with a radius of 300 mm. The cylinder is

positioned in the centre of the appliance. During the measurement, the opposite side of

the cylinder shall be covered;

– for appliances where the exposure position is not defined by the construction, such as

those placed on a table or some shoulder tanners, the measuring instrument is placed

parallel to the emitting surface at the shortest recommended exposure distance or directly

on the emitting surface;
– for appliances exposing a sitting person, the measuring instrument is placed on the

surface of a half-cylinder with a radius of 300 mm in case of full body exposure (positions
2, 3 and 4 of Figure 102) or of 150 mm in case of facial exposure (position 1 of
Figure 102). The half-cylinder is located in the position of the body part to be exposed.
The half-cylinder for the facial measurement is placed on a 50 mm base. In the transition
area between head and body, measurements are conducted in position 1 and position 2
and the higher effective irradiance is recorded.
Details of the instrument used for the measurements are given in IEC 61228. The measuring
instrument shall measure the mean irradiance over a circular area having a diameter not
exceeding 20 mm. The response of the instrument shall be proportional to the cosine of the
angle between incident radiation and the normal to the circular area. The spectral irradiance
shall be measured at intervals of 1 nm in an appropriate double monochromator system. The
double monochromator shall have a bandwidth not exceeding 2,5 nm.
32.102 The radiation from appliances incorporating VIS emitters or IR emitters shall be
limited.
Compliance is checked by the following test.
The appliance is fitted with VIS emitters or IR emitters, as appropriate, that have been
conditioned by supplying them at rated voltage for a period of approximately 5 h.
The appliance is supplied at rated voltage and the radiation from the appliance is measured
as detailed in 5.1 of IEC 62471:2006 at the exposure distance in Clause 6 of IEC 62471:2006
or at the recommended exposure distance, whatever is more unfavourable.
Irradiances from VIS appliances and IR appliances shall not exceed the limits of risk group 1
as specified in 6.1 of IEC 62471:2006.
32.103 Appliances that are not in the exempt group of IEC 62471 shall be supplied with at

least two pairs of protective goggles that ensure adequate front and side protection for the
eyes and that provide enough luminous transmittance to make it possible to see through
them.
Compliance is checked by inspection and by the following test that is carried out on each pair
of goggles.
The transmission is m
