Overview
EN 1297:2004 (CEN) defines a laboratory method for the artificial ageing of factory-made flexible sheets for roof waterproofing - bitumen, plastic and rubber sheets - by combined exposure to UV radiation, elevated temperature and water. The standard establishes a common accelerated-weathering procedure used to assess resistance to long-term outdoor ageing and to support follow-up performance tests in product standards.
Key topics and technical requirements
- Test principle: Cyclic exposure to UV, heat and spray to reproduce combined weathering effects; follow-up performance tests are carried out on exposed specimens.
- Light source: Fluorescent UV lamps Type I (340 nm) in accordance with EN ISO 4892-3; mean UV irradiance (≥ 300 nm) of 45 ± 5 W/m² at specimen plane; irradiance uniformity within ±10%.
- Exposure cycle: One cycle = 360 minutes (300 min dry / 60 min spray). UV is switched off during the wet period.
- Black standard temperature (BST): 60 ± 3 °C during the dry period; chamber air temperature controlled to achieve this BST within 30 minutes.
- Relative humidity: 10 ± 5% after 30 minutes of the dry period.
- Water and spray: Demineralized water with conductivity ≤ 500 µS/m; water temperature at spray start 25 ± 5 °C; spray flow 10 ± 3 L/min per m² of exposed surface.
- Specimen arrangement: Mounted flat ≥ 5° above horizontal on stainless-steel platens or in pans; machine direction indicated; attachment must allow free dimensional changes.
- Measurement & equipment: Radiometer for UV radiant exposure (300–400 nm), black standard thermometer, cycle timer/hour meter.
- Recommended exposure: Annex B suggests a total UV radiant exposure of about 800 MJ/m² (~5 000 hours), with intermediate inspections (e.g., every 1 000 h / 160 MJ/m²) for visual changes and cracking.
- Sampling & reporting: Sampling per EN 13416; test reports must record product ID, deviations, apparatus, sampling, procedure, results and date.
Applications and users
EN 1297 is used for:
- Manufacturers - quality control, product development and claims about ageing resistance.
- Testing laboratories - standardized accelerated ageing to generate comparable durability data.
- Specifiers, roof consultants and certifiers - assess long-term performance for roof waterproofing systems.
- R&D teams - compare formulations (bituminous membranes, PVC, EPDM, thermoplastics) under controlled accelerated weathering.
Practical uses include durability screening, compliance testing referenced by product standards (e.g., EN 13707, prEN 13956), and supporting life‑cycle and warranty evaluations.
