Urban testing site located at the roof of a 2-floor building of LNEG with high U.V. exposure and corrosivity C2-C3. It is a RUV 3 test site, according to the classification of EN 10169-2. This OET is recognized by the European Coil Coating Association (ECCA) as a reference testing site since 1990: https://www.prepaintedmetal.eu/890/sites

Additional information

Monitoring of atmospheric parameters: air temperature, relative humidity, solar irradiance, precipitation, wind speed and direction, time of wetness, with data collection every 10 seconds and storage every 10 minutes. Chloride deposition rate is evaluated by the wet candle method and sulfur dioxide deposition rate on lead dioxide sulfation plates (ISO 9225). The evaluation of the sulfur dioxide content in the atmosphere using a sensor is under development with data collection and storage, similarly to other parameters. The annual global radiation similar to that of Florida, but with a different distribution throughout the year. The cycle of UV radiation at Lumiar / Lisbon Test Site is best suited to the European location then that recorded in Florida, being thus more relevant for many European countries, and consequently for manufacturers of coil coated placing their products in these countries. The average annual temperature, as well as the annual distribution of temperature, relative humidity and rainfall are also more significant for European countries. Materials usually exposed: reference panels of different materials/metals, samples with organic coating, absorbers and reflectors surfaces, thermal solar collectors, polymeric materials, natural materials (e.g. wood), etc. Costs: Cost depends of samples dimensions and exposure time. Cost upon request.
