G01M TESTING STATIC OR DYNAMIC BALANCE OF MACHINES OR STRUCTURES; TESTING OF STRUCTURES OR APPARATUS, NOT OTHERWISE PROVIDED FOR
Introduced: September 1968
Description
G01M covers apparatus and methods for evaluating the balance characteristics of rotating or stationary machines and structural systems, including vibration analysis, alignment measurement, and integrity assessment. This subclass encompasses balancing machines for rotors, wheels, and similar components, as well as testing equipment for detecting deviations from desired operational conditions. It includes structural load testing, durability assessment, and non-destructive examination methods applied to apparatus not specifically classified elsewhere in G01. Applications range from automotive and aerospace component verification to industrial machinery maintenance and safety validation.
Additional Content IPC
Calibrating means ascertaining the quality of a measuring or testing device, or checking, adjusting graduations of measuring or testing device Monitoring means maintain a continuous or periodical watch (human or instrumental) on, to enable action to be taken or initiated, or a signal to be given, if undesired conditions occur Investigating means testing or determining. Testing means determination of the presence, quality, or genuineness of object to be tested.
IPC and CPC are identically structured here. All 11 subcodes exist in both systems.
4 shared codes have differing titles between IPC and CPC.
