Maximum service temperature is a measure indicating the maximum continuous temperature at which an insulation material can operate without any degradation in thermal insulation performance.MST is either measured according to:aximum Service Temperature (MST) under 500Pa â a guarantee that can be used for design. To estimate the highest continuous operating temperature at which a product can be used, a variety of methods exists.
The Maximum Service Temperature (MST) of U Thermo insulation solutions is declared according to EN ISO 14 706 and EN ISO 14 707. The tests measure performance under a load of 250-500 Pa depending on the density of the products to simulate real life installation conditions.
