Overview

EN 513:2026 is a European standard developed by CEN that specifies a method for assessing the resistance of poly(vinyl chloride) (PVC) based profiles to artificial weathering using xenon-arc radiation. The standard applies to a broad range of PVC-based profiles, including those covered with foils, paints, prints, thermo-laminated foils, or produced by coextrusion. By following this standard, manufacturers and laboratories can consistently test and compare how various PVC profiles perform over prolonged exposure to simulated sunlight and environmental stressors.

Artificial weathering tests are crucial for evaluating changes in colour and mechanical properties, ensuring product durability and maintaining quality in real-world conditions. EN 513:2026 supports quality control, research and development, and regulatory compliance in building, construction, and other industries using PVC profiles.

Key Topics

• Test Methods: EN 513 outlines the procedure for exposing PVC profiles to xenon-arc radiation under controlled conditions, replicating the effects of weathering.
• Applicability: The test covers both uncoated and coated (foiled, painted, thermo-laminated) PVC profiles.
• Weathering Conditions: Two exposure methods (M and S) are defined, each with specific cycles of UV irradiation, temperature, humidity, and water spray.
• Evaluation Criteria: The standard details how to determine changes in color (using grey scale and colorimetric coordinates), impact strength, flexural properties, chalking, adhesion, and peel strength.
• Test Reporting: It stipulates comprehensive test report requirements, ensuring transparency and reproducibility of results.
• Annex for Color and Properties: Annex A provides guidance for measuring changes in colour and mechanical properties after exposure.
• Reference Methods: EN 513 references relevant ISO and EN standards for vocabulary, specimen preparation, and analysis methods.

Applications

EN 513:2026 delivers significant practical value across several sectors:

• Building & Construction: Manufacturers of window and door profiles, cladding, and finishing profiles use this standard to prove their products’ resistance to outdoor weathering.
• Quality Assurance: Companies rely on the methods in EN 513 to meet regulatory requirements and customer specifications for weathering durability.
• Product Development: R&D laboratories use the testing procedures to optimize the formulation and coatings of PVC profiles, ensuring long-term color stability and mechanical integrity.
• Coated Product Validation: The standard supports validation for profiles with decorative films, paints, or laminates, verifying that covering systems maintain adhesion and appearance during service life.
• Third-party Testing: Laboratories performing independent certification or market surveillance employ EN 513 to provide objective evaluation of weathering performance.
• Specification and Procurement: Architects, specifiers, and procurement professionals reference EN 513-compliant test results for selecting robust, reliable PVC profile products.

Related Standards

For comprehensive testing and compliance, EN 513:2026 is used alongside several related standards:

• EN ISO 4892-1 & EN ISO 4892-2: Methods of exposure to laboratory light sources, specifically xenon-arc lamps, for plastics.
• EN ISO 472: Definitions and vocabulary for plastics.
• ISO 9370: Instrumental determination of radiant exposure in weathering tests.
• EN ISO/CIE 11664-4 / 11664-6: Color measurement and assessment.
• EN ISO 179-1: Determination of Charpy impact properties.
• EN ISO 178: Flexural properties testing for plastics.
• EN 12608-1: Classification and testing for unplasticized PVC (PVC-U) profiles for building applications.
• EN ISO 8256: Tensile impact strength determination.
• EN ISO 4628-6: Chalking evaluation.
• EN ISO 2409: Adhesion of coatings (cross-cut test).
• EN 17271: Determination of peel strength of PVC profiles laminated with foils.
• EN 13245-2: Impact testing for PVC-UE profiles.

By adhering to EN 513:2026 and these related standards, organizations ensure consistent, reliable testing of PVC profiles, supporting innovation, durability, and customer trust in PVC-based solutions.

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 4892-1:2024, 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 4892-1:2024, 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.
oSIST prEN 513:2025
prEN 513:2025 (E)
Store in the dark the non-exposed reference test specimens.
8 Conditioning
