How come that pipes are said to be resistant to 95º while they read 70º?
plomyPEX and plomyLAYER pipes are certified by AENOR in Spain and by LNEC in Portugal. The Portuguese certification body LNEC obliges us to mark every meter of pipe as belonging to Class 2, which corresponds to 70 ºC. Nevertheless, both plomyPEX and plomyLAYER pipes are also marked as belonging to Class 5, which is the most restrictive one and corresponds to high-temperature heating installations suitable for water temperatures of up to 95 ºC. For purposes of clarity, this is the classification: Class 1: Water up to 60 ºC Class 2: Water up to 70 ºC Class 4: Radiant in-floor heating or low-temperature radiators.
