What is ISO 463 — Mechanical dial gauges about?
ISO 463 is an international standard that covers geometrical product specifications for dimensional measuring equipment.
ISO 463 specifies the most important design and metrological characteristics of mechanical dial gauges.
ISO 463 stipulates the technicalities such as related terms, definitions, design characteristics, dimensions, zero adjustments, metrological characteristics, measuring forces, proving conformance, calibration of metrological characteristics, marking, etc. for mechanical dial gauges.
Who is ISO 463— Mechanical dial gauges for?
ISO 463 on mechanical dial gauges is relevant to:
- Designers of mechanical dial gauges
- Manufacturers of mechanical dial gauges
- Suppliers and exporters of mechanical dial gauges
- Metrologists
- Mechanical engineers
- Regulatory authorities
Why should you use ISO 463 — Mechanical dial gauges?
A mechanical dial gauge is a measuring instrument in which the axial displacements of a plunger are transmitted and magnified by suitable mechanical means to a pointer that rotates in front of an analogue circular scale.
ISO 463 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard. ISO 463 specifies all the technicalities such as design characteristics, metrological characteristics, and other essential specifications required for the construction of good quality mechanical dial gauges. ISO 463 influences the chain-link 5 of the chains of standards on size, distance, a form of a line independent of datum, a form of a line dependent of datum, form of a surface independent of datum, orientation, location, circular run-out and total run out in the general GPS matrix. ISO 463 presents more detailed information on the relation of the standard as compared to other standards and the GPS matrix model. It recommends the general design and workmanship so that the performance of the dial gauge complies with the requirements of global standards. ISO 463 guides you for the design and rigidity of the mechanical dial gauges, such that the freedom of movement of the plunger is not impaired by clamping the stem of the instrument (provided that such clamping is applied to the minimum extent necessary to achieve a stable mounting).
ISO 463 proves to be useful for you, as it provides a reliable means of resetting the gauge to zero for each dial gauge, that cannot be unintentionally displaced (other than by the application of excessive force), e.g., through the provision of setting a locking device such as a clamp or by frictional resistance
