The environmental, or climate chamber, allows products to be tested against simulated environmental factors such as temperature and humidity.
The temperature and humidity within the chamber can be raised and lowered in cycles to simulate accelerated end-use conditions, while additional weathering chambers can be used to simulate exposure to accelerated rainfall.
For CE marking of reactive materials, including intumescents, we have the facilities to conduct the testing both before and after exposure to enable type X, Y, Y2, Z, or Z2 durability to be demonstrated. The environmental chamber allows samples to be pre-conditioned in line with ETAG 026 ‘Guideline for European Technical Approvals for Fire Stopping and Fire Sealing Products’ and its supporting TR024 technical report.
The fire retardant properties of timber products can be tested in line with prEN 16755 (to supersede TS 15912). This standard uses the environmental chamber to gain evidence for any increase in hygroscopicity through the addition of fire retardants to timber products and any decrease in the fire performance after exposure to accelerated climatic conditions. We offer testing for INT1, INT2 and EXT durability of reaction to fire classifications.
We can also undertake supporting testing required to gain Type HR (humidity resistant) and LR (leach resistant) specifications under the UK Wood Protection Association’s Flame Retardant Specification Manual and ‘WPA Benchmark' certification scheme for industrial flame retardant treatment of solid timber and panel products.
