This International Standard specifies the general requirements, terms and definitions of characteristics of
simple GPS measuring equipment, e.g. micrometers, dial gauges, callipers, surface plates, height gauges,
gauge blocks, but not necessarily excluding more complicated equipment. It forms the basis for standards
defining and describing the design characteristics and metrological characteristics for measuring equipment. It
also gives guidance for the development and content of standards for GPS measuring equipment.
This International Standard is intended to ease the communication between manufacturer/supplier and
customer/user and to make the specification phase of GPS measuring equipment more accurate. This
International Standard is also intended as a tool to be used in companies in the process of defining and
selecting relevant characteristics for measuring equipment to be used in the quality assurance of measuring
processes, i.e. in calibration and in workpiece measurements.
This International Standard also includes terms which are frequently used in connection with the
characterization of specific measuring equipment.
