Describes and illustrates types and design features of commonly used gauges and specifies their main parameters and minimum quality requirements. Only the features absolutely necessary to ensure interchangeability of parts, rigidity and stability of construction and ease and reliability of gauges in use are specified, leaving further details of design to individual designers.
