Overview
The draft international standard oSIST prEN ISO 877-2:2016:2016, titled Plastics - Methods of exposure to solar radiation - Part 2: Direct weathering and exposure behind window glass, establishes testing methods for evaluating the effects of solar radiation on plastics. Developed under the CEN framework and ISO/TC 61/SC 6, this document defines procedures for two specific exposure scenarios: direct outdoor weathering and exposure behind window glass. While the work item was abandoned following ISO's cancellation decision, the document provides valuable guidance for assessing how solar radiation alters the properties of polymeric materials.
This standard is an essential reference for manufacturers, testing laboratories, and researchers concerned with the durability and longevity of plastics under natural environmental conditions, particularly solar UV exposure.
Key Topics
Exposure Methods:
- Method A: Direct exposure of plastic specimens to outdoor solar radiation at a specified angle and location.
- Method B: Exposure of plastics behind a glass cover simulating solar radiation filtered through window glass, mimicking indoor or behind-glass conditions.
Test Fixtures and Apparatus:
- Design requirements for specimen racks ensuring proper orientation, ventilation, and minimal mechanical stress.
- Use of corrosion-resistant materials such as aluminum alloys (6061T6, 6063T6) or stainless steel for test fixtures.
- Specific design for method B involving an open-bottomed box with a glass cover, maintaining a minimum ventilation gap (75 mm) between specimens and glass.
- Routine monitoring or replacement of window glass to maintain consistent transmission of UV radiation, with emphasis on pre-aging glass for 3 months to stabilize spectral transmission.
Exposure Conditions:
- Determination of exposure angles (0°–90° tilt) aimed at simulating intended application environments, commonly 5° or 45°.
- Specification of minimum clearance to ground or obstructions to ensure accurate exposure.
- Climatic and solar radiation measurement requirements, including positioning of radiometers parallel to specimens for accurate data collection.
Evaluation and Reporting:
- Assessment of property changes induced by solar radiation exposure using standardized procedures.
- Recording of climatic conditions such as temperature, solar irradiance, and duration of exposure.
- Detailed documentation in test reports for reproducibility and regulatory compliance.
Applications
- Material Durability Testing: This standard supports the simulation and assessment of long-term outdoor and indoor sunlight exposure impacts on plastics used in automotive, construction, packaging, and consumer goods industries.
- Product Development and Quality Control: Enables manufacturers to test plastics for UV resistance, color stability, and mechanical property retention under realistic solar exposure conditions.
- Regulatory Compliance: Assists in meeting international quality and safety standards by providing reliable methods to verify plastic materials’ weathering performance.
- Research and Innovation: Offers a framework for scientists studying polymer degradation mechanisms under natural sunlight and glass-filtered solar radiation.
