DEFINITION

Classification: 73/570

VIBRATION:

(under the class definition) Subject matter for (1) testing an article or mechanism by subjecting it to vibratory forces for determining qualities, characteristics or conditions thereof, or (2) sensing, study or analysis of vibrations otherwise generated in or existing in the article or mechanism.

(1) Note. The "article or mechanism" will be hereinafter referred to as a "body" or "test body".
