This International Standard gives a classification of, and specifies requirements for, denture base polymers; it also specifies the test methods to be used to determine compliance with these requirements.

This International Standard applies to the following denture base polymers :

a) poly(acrylic acid esters);

b) poly(substituted acrylic acid esters);

c) poly(vinyl esters);

d) polystyrene:

e) rubber modified poly(methacrylic acid esters);

f) polycarbonates;

g) polysulfones;

h) copolymers or mixtures of the polymers listed in a) to g).

Although this International Standard does not require manufacturers to declare details of the composition, attention is drawn to the fact that some national or international authorities require details to be provided to them.
