EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 8502-4 testing. ISO 8502-4 provides guidance on estimating the likelihood of condensation on the surface to be painted. It can be used to determine whether the conditions at the work site are suitable for painting.
International Standards ISO 8501, ISO 8502 and ISO 8503 are prepared to provide methods for assessing these factors, while ISO 8504 provides guidance on the preparation methods available for cleaning steel Surfaces and indicates the abilities of each to achieve specified levels of cleanliness.
This series of International Standards does not contain recommendations for protective coating systems to be applied to steel surfaces. Although surface quality can have a direct impact on the selection and performance of the protective coating to be applied, it does not contain recommendations on surface quality requirements for specific situations. Such recommendations are also found in other documents, such as national standards and codes of practice.
The relative humidity of the air and the temperature of the steel surface provide the basis for estimating the likelihood of condensation, but there is no simple rule to apply. The situation is complicated because there are a large number of factors that have an impact on the condensation and evaporation of moisture:
These factors sometimes induce surface wetting or inhibit local drying; where the surface temperature remains low or tends to fall due to heat losses, or where the air becomes rapidly saturated due to reduced ventilation. Naturally, the same factors sometimes have the opposite effect. Therefore, any test results should be interpreted with great caution.
