evaluation
Casting materials are difficult to evaluate since they possess their service
properties only
after
being formed into a splint, cast, or brace. Thus, their
mechanical properties depend both on design and manufacturing features
and
on technical aspects of application. After many attempts at producing
evaluation procedures, in the American Society for Testing and Materials
and elsewhere, present activities are focusing on two methods:
1. A “handleability” or “conformability” evaluation that involves
forming a standard shape about a mandrel or constructing a stan-
dard structure, such as short forearm cast, and awarding points for
