Technical Specification - UNDP

the chemical to which it is exposed, but also on the concentration, the temperature
during the period of contact, the length of this period and the stress conditions within
the molding. When contact is brief, P.C. may, therefore, show adequate resistance to
a number of chemicals to which it is not resistant under the test conditions described
above. It is recommended that a separate test be conducted in situations where the
service conditions differ from the above test conditions.
In selecting the test media, the most important ones were chosen from all fields. In
many cases it will be possible, on the basis of this information, to draw conclusions as
to the behavior of chemically similar media not tested here. In case of doubt, a
compatibility test of specific materials with Paltough P.C. can performed in the
Paltough Laboratory.
