Overview
EN 513:2018 - "Plastics - Poly(vinyl chloride) (PVC) based profiles - Determination of the resistance to artificial weathering" is a CEN standard that specifies a laboratory method to expose PVC-based profile specimens to xenon‑arc radiation to assess changes in appearance and properties caused by simulated sunlight and moisture. It applies to PVC profiles including those covered with foil, lacquered or co‑extruded, and includes an informative Annex A describing evaluation of colour change and mechanical-property variations.
Key topics and technical requirements
- Test principle: Exposure of profile surface specimens to xenon‑arc radiation under controlled irradiance, temperature and humidity, then measurement of changes in characteristics.
- Apparatus: Requirements reference EN ISO 4892‑1 and EN ISO 4892‑2 (xenon‑arc lamps), plus black‑standard thermometer (BST), white‑standard thermometer (WST), radiant exposure monitoring (ISO 9370) and open‑frame specimen holders.
- Test methods: Two defined exposure cycles - Method 1 (102 min dry / 18 min water spray) and Method 2 (114 min dry / 6 min water spray) - with specified spectral irradiance, BST/WST temperatures and relative humidity control.
- Specimens and conditioning: Specimens are taken from the profile surface with the longitudinal direction retained; non‑exposed references are stored in the dark. Conditioning before exposure is generally not required unless otherwise specified.
- Procedure & monitoring: Control and record chamber air temperature, BST, WST and irradiance. Stop exposure when the required radiant exposure (J/m²) is reached.
- Test report content: Must cite EN 513, method used (M or S), laboratory ID, profile identification, apparatus details, BST/WST and chamber conditions, cycle, radiant exposure, exposure time and any deviations.
- Annex A (informative): Guidance on visual colour assessment (grey scale, colourimetry) and on determinations of Charpy impact, tensile impact, flexural properties, chalking, coating adhesion, peel strength and falling‑weight impact (for PVC‑UE).
Applications
- Quality control and weathering performance testing for PVC window frames, door profiles, cladding, fascias and other exterior PVC profile products.

5 Principle
Specimens taken from the surface of a profile, submitted to weathering in practice, are exposed to
xenon-arc radiation at specified irradiance, black and white standard temperatures, relative humidity
and spray cycle.
After the exposure, the changes in characteristics of the specimens are determined.
6 Apparatus
The apparatus shall comply with EN ISO 4892-1 and EN ISO 4892-2 and shall include:
a) a xenon-arc lamp in accordance with method A of EN ISO 4892-2:2013 with a spectral irradiance in
the band pass of 300 nm to 800 nm of (550 ± 55) W/m or a spectral irradiance in the band pass of
2 2
300 nm to 400 nm of (60 ± 2) W/m or a spectral irradiance at 340 nm of (0,51 ± 0,02) W/(m nm).
NOTE 1 In apparatuses with rotating specimen holders the relation of UV/(UV+VIS) irradiance depends
strongly on the reflection behaviour of the specimens in the test chamber. The reflection of the specimens is
wavelength dependent. The UV/(UV+VIS) relation is not a constant. The relation changes with the reflection
behaviour of the specimens.
NOTE 2 Comparing apparatuses controlled at different wavelength ranges tolerances can be higher due to
the conversion. Typical ranges are (550 ± 120) W/m for a spectral irradiance in the band pass of 300 nm to
800 nm, (60 ± 12) W/m for a spectral irradiance in the band pass of 300 nm to 400 nm and
(0,51 ± 0,08) W/(m nm) for a spectral irradiance at 340 nm.
b) a black-standard thermometer (BST) in accordance with EN ISO 4892-1:2016, 5.2, and
EN ISO 4892-2:2013, 6.2.1, and a means of recording temperatures during one cycle;
c) a white-standard thermometer (WST) in accordance with EN ISO 4892-1:2016, 5.2, and
EN ISO 4892-2:2013, 6.2.1, and a means of recording temperatures during one cycle;
d) a device to determine the radiant exposures stated in a) according to ISO 9370;
e) specimen holders in the form of an open frame, leaving the back of the specimen exposed according
to EN ISO 4892-2:2013, 4.6.
7 Test specimens
The number of test specimens shall be as specified in the referring standard.
NOTE Additional details regarding test specimens for determining changes in colour and variations of
properties after exposure of PVC based profiles to xenon-arc radiation are given in Annex A.
The test specimens shall be taken from the surface of the profile, exposed to UV radiation, such that the
longitudinal directions of the test specimens and the profile are the same.
Store in the dark the non-exposed reference test specimens.
8 Conditioning
Unless otherwise specified, conditioning is not required before an exposure to laboratory radiation
sources.
NOTE Additional details regarding conditioning before determining changes in colour and variations of
properties after exposure of PVC based profiles to xenon-arc radiation are given
