Overview

EN 477:2018 is a European Standard developed by CEN that specifies a reliable and repeatable method for determining the impact resistance of poly(vinyl chloride) (PVC) based profiles. Specifically, it focuses on unplasticized PVC (PVC-U) profiles tested at a low temperature of −10 °C by using a falling mass impact test. This standard supports manufacturers, testing laboratories, and quality control professionals in assessing the durability and mechanical resilience of PVC profiles, which are widely used in construction, window frames, and other structural applications.

By standardizing the method, EN 477:2018 ensures consistent measurement of impact resistance, providing transparency and comparability across European markets. This standard supersedes the earlier version EN 477:1995, reflecting the latest best practices and equipment specifications.

Key Topics

• Scope and Applicability
  The standard applies primarily to unplasticized poly(vinyl chloride) profiles (PVC-U), but it can also be utilized for other PVC-based profiles under defined temperature and testing conditions.

• Test Conditions
  Profiles are conditioned at a constant temperature of −10 °C for at least one hour prior to testing, which simulates cold-weather performance.

• Test Specimens
  Specimens are cut to a length of 300 mm, with ten samples used for each test batch to ensure statistical reliability.

• Impact Test Method
  A known mass (1,000 ± 5 g) with a hemispherical striking surface is dropped from a specified height onto the profile at a point between the inner webs (partition walls) of the profile. The apparatus includes guided rails and a rigid support system to prevent specimen movement or tilting during impact.

• Measurement and Results
  After impact, visual examination is conducted to identify any surface failures. The results include the number of specimens tested and the number broken, which helps determine the profile’s resistance to impact.

• Documentation
  A detailed test report is required, with information such as the profile identification, test laboratory, testing date, impact height, number of specimens tested, and any conditions or anomalies that could influence the results.

Applications

EN 477:2018 is essential for industries involved in the manufacture, testing, and certification of PVC-based profiles. Typical practical applications include:

• Building and Construction
  Ensuring that window, door, and facade profiles meet the required mechanical impact resistance, especially for exterior applications subjected to cold climates.

• Quality Control and Product Development
  Facilitating material performance evaluation during product design, material selection, and continuous production quality monitoring.

• Regulatory Compliance
  Supporting compliance with European directives and harmonized product standards requiring impact resistance data for PVC profiles.

• Third-party Testing and Certification
  Used by independent laboratories to verify manufacturers’ claims and provide certification for market acceptance.
