Scope

1.1 This section classifies denture base polymers and copolymers, specifies requirements, and specifies the tests to be used to determine compliance.
The method of inspection, and the requirements for the packaging, marking of the product and the instructions for use of the applied materials. This section applies to the system
The denture base polymers of the impact-resistant materials of the manufacturer's declaration also specify their respective requirements and test methods.
1.2 Examples of denture base polymers referred to in this section are as follows.
a) polyacrylates;
b) polyacrylates containing substituents;
c) polyvinyl esters;
d) polystyrene;
e) rubber modified polymethacrylates;
f) polycarbonates;
g) polysulfones;
h) polydimethacrylates;
i) polyacetal polyoxymethylene;
j) Copolymers or mixtures of the polymers listed in a) to i).
