What is ISO 3611- Micrometers for external measurements about?
ISO 3611 is an international standard that covers aspects of geometrical product specifications (GPS).
ISO 3611 specifies the most important design and metrological characteristics of micrometers for external measurements:
- With analogue indication
- With a digital indication, mechanical or electronic digital display
ISO 3611 stipulates the technicalities such as related terms and definitions, design characteristics, general design, main dimensions, metrological characteristics, proof of conformance with specifications, etc., for micrometers for external measurements.
Who is ISO 3611- Micrometers for external measurements for?
ISO 3611 on micrometers for external measurements is relevant to:
- Manufacturers of micrometers for external measurements
- Manufacturers of analogue indicating devices
- Designers of micrometers for external measurements
- Metrologists
- Testing authorities
Why should you use ISO 3611- Micrometers for external measurements?
A micrometer for external measurements is a measuring instrument that gives the evaluation of a dimensional quantity of an external feature of a workpiece based on the movement of a spindle with a measuring face, moving to a material measure and an anvil, with the movement generated by a screw thread. ISO 3611 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard.
ISO 3611 provides you with the information on design and metrological characteristics of micrometers for external measurements. ISO 3611 estimates the preparation of the general design and workmanship of the micrometer for external measurements, in such a manner that its metrological characteristics comply with the requirements of global standards, under all operational orientations. ISO 3611 specifies the metrological characteristics, that apply when the zero or reference point is set at any position within the measuring range, i.e., in floating zero mode.
ISO 3611 helps the users to produce the micrometers for external measurements that comply with the maximum permissible error (MPE) and permissible limit (MPL) values at any orientation of the micrometer. ISO 3611 influences the chain-link 5 of the chain of standards on size in the general GPS matrix. ISO 3611 also presents users with the test methods to evaluate the performance of the micrometer.
