DEFINITION

Classification: 73/760

SPECIMEN STRESS OR STRAIN, OR TESTING BY STRESS OR STRAIN APPLICATION:

(under the class definition) Subject matter for (a) the measurement or study of stress (load) or strain (deformation) of a specimen of material or structure, or (b) the testing of a specimen of material or structure by application of a stress or strain thereto.

(1) Note. Where a stress or strain determination is made as a part (i.e., subcombination) of a larger measuring or testing organization (e.g., vane type fluid flow measurement, accelerometer) classification will be with the larger testing organization.

152.48, for a downhole apparatus for determining a characteristic of a borehole, a well casing, or a drill rigging by measuring force during drilling.

152.49, for a nondownhole-type apparatus for determining a characteristic of a borehole, a well casing, or a drill rigging by measuring force during drilling.

152.59, for a downhole-type apparatus for determining a characteristic of a borehole, a well casing, or a drill rigging by measuring a response due to force while drilling

is not taking place.

862+, for dynamometers where strain in a part of the measuring apparatus itself is utilized as an index of power applied thereto or transmitted thereby. SEE OR SEARCH CLASS
