Описание (английский):

This International Standard specifies the most important design and metrological characteristics of gauge blocks with a rectangular cross section and a nominal length ln ranging from 0,5 mm to 1000 mm. Limit deviations and tolerances are stated for the calibration grade K and for the grades 0, 1 and 2 for various measuring purposes.

Overview - ISO 3650:1998 (Gauge blocks, GPS - Length standards)

ISO 3650:1998 is an International Standard in the Geometrical Product Specifications (GPS) family that defines the design and metrological requirements for gauge blocks (rectangular cross section) with nominal lengths from 0.5 mm to 1000 mm. It specifies limit deviations and tolerances for calibration grade K and grades 0, 1 and 2, and sets the basis for traceable length measurement used in calibration and precision metrology.

Key topics and technical requirements

Scope and definitions: Nominal length, central length, variation in length, flatness, and wringing behaviour are defined for consistent use in calibration and inspection.

Reference conditions & traceability: Lengths and calibrations are referenced to the metre and apply at a reference temperature of 20 °C and standard pressure (101 325 Pa). Traceability is established via an unbroken chain of calibrations ultimately linked to interferometric standards.

Materials & surface finish: Gauge blocks shall be made of wear‑resistant materials (commonly hardened steel). Steel measuring faces require Vickers hardness ≥ 800 HV 0.5 and surfaces that will wring reliably.

Thermal behaviour: The coefficient of thermal expansion for steel blocks in the 10–30 °C range is given (with stated uncertainty) so users can apply temperature corrections.

Dimensional and marking rules: Cross‑section dimensions, marking of nominal length and grade, and support‑mark positions for long blocks (over 100 mm) are specified.

Metrological requirements: Flatness, parallelism, perpendicularity and allowable variation in length are prescribed per grade.

Calibration methods: Procedures include interferometry (with auxiliary plate and correction rules), comparison measurement, wringing tests, and requirements for calibration certificates and uncertainty statements.

Orientation & support: Measurement orientation differs by length (vertical for ≤100 mm; supported horizontal for >100 mm) with specified support positions.

Applications and who uses ISO 3650

Calibration laboratories and national metrology institutes for producing traceable gauge‑block calibrations.

Quality control and inspection departments in precision manufacturing, aerospace, automotive and tooling industries.

Metrology equipment suppliers designing interferometers, comparison rigs and wringing fixtures.

Standards and conformity assessment bodies applying GPS for dimensional chains.

Related standards

ISO 1 (reference temperature), ISO 1101 (geometrical tolerancing), ISO 6507-1 (Vickers hardness), ISO 14253-1 (inspection decision rules), and the International Vocabulary of Metrology (VIM). Annex B of ISO 3650 maps the standard to the GPS matrix model.

ISO 3650:1998 is essential for anyone specifying, calibrating or using gauge blocks as primary length standards, ensuring traceable, repeatable and internationally comparable dimensional measurements.
