Shortenings in the table:

+ – guaranteed chemical resistance during the estimated service life according to DVS 2205

+/s – reduced service life due to the possibility of premature aging of the material (cracking)

+/o – reduced service life due to the possibility of premature aging of the material (oxidation)

+/q – reduced service life due to the possibility of premature aging of the material (swelling)

С – material is chemically resistant;

О – the material is chemically relatively resistant, in the medium of a given concentration at an elevated temperature, pipes with an increased margin of safety should be used;

Н – the material is not chemically resistant, in the medium of a given concentration at a given temperature, the use is unacceptable;

(-) – no data.
