Annex T
(normative)
UV-C radiation effect on non-metallic materials
Annex T provides requirements for non-metallic materials subject to direct or reflected UV-C
radiation (100 nm to 280 nm) exposure and whose mechanical and electrical properties are
relied upon for compliance with this standard. This annex does not apply to glass, ceramic
and similar materials.
NOTE 1 General-purpose incandescent and fluorescent lamps with ordinary glass envelopes are not considered
to emit significant UV-C radiation.
The UV-C radiation effect on non-metallic materials is determined by measuring selected non-
metallic material properties before and after UV-C radiation conditioning. The conditioning
and tests are carried out on non-metallic material specimens prepared according to the
relevant standard for the test method. The standards and compliance criteria for parts
providing mechanical support or impact resistance are specified in Table T.1. The standard
and compliance criteria for electrical insulation of internal wiring are specified in Table T.2.
The conditioning apparatus and test procedure are as specified in ISO 4892-1 and
ISO 4892-2, with the following modifications.
Modifications to ISO 4892-1:
5.1 Light source
5.1.6 The UV-C emitter shall be a low pressure mercury lamp with a quartz envelope having
a continuous spectral irradiance of 10 W/m at 254 nm.
NOTE The quartz envelope blocks the 185 nm resonant wavelength for mercury that can generate ozone.

Subclause 5.1.6.1 and Table 1 are not applicable.
5.2 Temperature
5.2.4 The black-panel temperature shall be 63 °C ± 3 °C.
5.3 Humidity and wetting
5.3.1 Humidification of the chamber air is specified in part 2 when necessary.
9 Test report
This clause is not applicable.
Modifications to ISO 4892-2:
7 Procedure
7.1 General
At least three test specimens of each non-metallic material providing mechanical support or
impact resistance shall be exposed in each run to allow statistical evaluation of the results.
Ten samples of the insulated internal wiring shall be exposed in each run. When the internal
wiring is provided in more than one colour, the colour having the heaviest organic pigment
loading is used.
In determining the samples for testing, consideration should be given to samples coloured red
or yellow which are known to have particular critical effects.
7.2 Mounting the test specimens
The specimens shall be attached to the specimen holders such that they are not subject to
any applied stress.
7.3 Exposure
Before placing the specimens in the test chamber, the apparatus shall be operating under the
specified exposure conditions. It shall be programmed to operate continuously and the
conditions shall be maintained throughout the exposure, keeping any interruptions to service
the apparatus and to inspect the specimens to a minimum.
The test specimens and, if used, the irradiance-measuring instrument are exposed for
1 000 h.
NOTE Repositioning of the specimens during exposure is desirable and might be necessary.
If it is necessary to remove a test specimen for periodic inspection, care should be taken to
avoid touching the exposed surface or altering it in any way.
7.4 Measurement of radiant exposure
If used, a radiometer shall be mounted and calibrated such that it measures the irradiance at
the exposed surface of the test specimen.
