Overview
EN 479:2018 is a European Standard developed by CEN that specifies the method for determining the heat reversion of unplasticized poly(vinyl chloride) (PVC-U) profiles at 100 °C in air. This standardized test method is crucial for evaluating the dimensional stability of PVC-based profiles when exposed to elevated temperatures. The standard is applicable to PVC-U profiles and can be adapted to other PVC-based profiles by adjusting temperature or test conditions accordingly. EN 479:2018 supersedes the previous EN 479:1995 standard, reflecting updated procedures and requirements.
Key Topics
- Heat Reversion Measurement: The standard defines heat reversion as the percentage change in length of heat-exposed PVC profiles, an indicator of the material’s ability to maintain shape under thermal stress.
- Test Conditions: Testing is performed at a controlled temperature of 100 °C with forced air circulation, ensuring consistent exposure and heat transfer.
- Specimen Preparation: Profiles are prepared as minimum 250 mm samples, marked with two points 200 mm apart for precise measurement before and after heating.
- Test Procedure: Specimens are conditioned at room temperature, then heated for 1 hour at 100 °C, followed by cooling to ambient temperature for post-test length measurement.
- Result Calculation: Heat reversion (R) is calculated as a percentage using the difference between initial and final lengths relative to the initial length. Where applicable, differences between opposing surfaces (ΔR) are also assessed.
- Reporting Requirements: The test report must include details such as profile identification, test conditions, measurement data before and after heating, calculated heat reversion values, and any deviations or incidents during testing.
Applications
- Construction and Building Materials: Ensuring that PVC-U window, door, and façade profiles maintain their dimensional stability at elevated temperatures, which directly impacts durability and performance.
- Quality Control: Manufacturers of PVC-based profiles utilize this standard to evaluate and certify product compliance with European regulations and industry benchmarks.
- Product Development: Material scientists and engineers can apply the test to optimize formulations of PVC profiles for enhanced thermal resistance.
- Regulatory Compliance: EN 479:2018 supports compliance with EU directives requiring performance standards for plastic profile materials used in building envelopes and other structural applications.
- Research and Testing Laboratories: Standardized procedures facilitate consistency in inter-laboratory comparisons and certification testing for PVC profile products.
