DEFINITION

Classification: 73/849

Bending, flexing, or folding:

(under subclass 788) Subject matter where the specimen has at least one axis and the difference in angular orientation of the ends of the axis is varied by the applied load.

SEE OR SEARCH THIS CLASS, SUBCLASS:

812, for such subject matter where the angular variation is repetitively effected.
