Accelerated weathering enhancement via environmental stress cracking
Impact Solutions offers a novel testing protocol combining accelerated weathering with environmental stress cracking (ESC) to significantly reduce assessment times of UV ageing on products. This method predicts material degradation and compliance with ASTM standards in under two months.
Overview
Impact Solutions presents an innovative testing approach that combines accelerated weathering with environmental stress cracking (ESC) to assess the influence of UV exposure on products like roof tiles. This method aims to shorten the duration of current accelerated testing programs, which typically require several months, to less than two months. By integrating ESC, the testing can predict whether materials will meet ASTM standards and provide insights into their real-world degradation.
Technical specifications
- Accelerated weathering and ESC combination: This dual approach enhances the prediction of material degradation by correlating ESC results with accelerated weathering data.
- ASTM D6878 compliance: The protocol includes testing under ASTM D6878 conditions, allowing for adjustments to ESC conditions to optimize testing parameters.
- Material versatility: Initially tested on a small number of materials, the method is adaptable to various polyethylene (PE) materials, expanding its applicability.
- Data correlation: Results are correlated with client databases to enhance prediction accuracy for material performance over potential service lifetimes.
Technology readiness level
This advanced testing protocol is at a Technology Readiness Level 6, indicating that it has been tested in a relevant environment and is ready for further validation and potential commercialization.
