The following symbols and abbreviations are used to
indicate the composition of the flow substances:
% Percentages refer to mass proportions in %.
VL Aqueous solution, mass proportion <= 10%.
L Aqueous solution, mass proportion > 10%.
GL Aqueous solution saturated at 20°C.
TR Chemical is at least technically pure.
H Normal commercial composition.
S Traces < 0.1%.
G Usual mass proportion of any saturated
solution or dilution.
Data is based on immersion tests without mechanical load
and reflects current levels of knowledge. No claims under
guarantee may be made on the basis of this information.

Explanation
When the pipe wall material comes into contact with
substances flowing through the pipe, different processes
can take place, such as the absorption of liquid (swelling),
the extraction of soluble elements in the material
(shrinkage) or chemical reactions (hydrolysis, oxidation
etc), that can sometimes cause the properties of the pipe
or pipeline parts to change.
The performance of pipes and pipeline parts when in
contact with effluent substances can be classed as follows:
NB: Does not cover systems incorporating EPDM seal rings.
Resistant
The pipe wall material is generally regarded
as being suitable.
Limited resistance
The suitability of the pipe wall material must be
checked in each individual case and, if necessary,
further tests should be carried out.
Not resistant
The pipe wall material is generally regarded
as being unsuitable.
