Scope

• Bitumen, plastic and rubber sheets for roof waterproofing;
• Plastics;
• Coatings;
• Liquid applied roof waterproofing systems.

Standards

• EN 1296 – Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roofing - Method of artificial ageing by long term exposure to elevated temperature
• EN 1297 – Flexible sheets for waterproofing - Bitumen, plastic and rubber sheets for roof waterproofing - Method of artificial ageing by long term exposure to the combination of UV radiation, elevated temperature and water
• EN ISO 4892-2 - Plastics - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps

Principle

Artificial ageing / weathering of materials and products by exposure to (a combination of) elevated temperature, moisture and radiation (UV, xenon). Before and after ageing/weathering product characteristics (e.g. strength, strain, stability, colour) are measured to determine the resistance to ageing / weathering.
