Full title and description
Geometrical Product Specifications (GPS) — Length standards — Gauge blocks. This International Standard specifies the principal design and metrological characteristics, limit deviations and tolerances for gauge blocks with rectangular cross section and nominal lengths from 0.5 mm to 1 000 mm (calibration grade K and grades 0, 1 and 2 are covered).
Abstract
ISO 3650:1998 defines the dimensional, design and metrological requirements for gauge blocks used as length standards, including nominal length range, cross‑section form and the limit deviations/tolerances for calibration and working grades. A technical corrigendum (Cor 1:2008) applies to the base document.

- Number of pages: 15 (ISO edition).
Scope
Specifies the most important design and metrological characteristics of rectangular‑section gauge blocks with nominal lengths ln from 0.5 mm up to 1 000 mm; it gives limit deviations and tolerances for calibration grade K and tolerance grades 0, 1 and 2 for different measuring purposes. The standard is part of the ISO GPS (geometrical product specifications) framework and references related GPS standards for tolerancing, inspection rules and reference temperature.
Key topics and requirements
- Design and dimensional characteristics for rectangular gauge blocks (cross‑sectional form, end‑face and edge requirements).
- Nominal length range: 0.5 mm to 1 000 mm.
- Limit deviations and tolerances specified for calibration grade K and grades 0, 1 and 2.
- Normative references to GPS documents (for example ISO 1101 on geometrical tolerancing, ISO 14253‑1 on inspection decision rules, and ISO 1 reference temperature).
- Includes a published technical corrigendum (ISO 3650:1998/Cor 1:2008).
Typical use and users
Used by national metrology institutes, calibration laboratories, manufacturers of gauge blocks and precision measurement equipment, QA/metrology departments in industry, and standards bodies. Typical applications include calibration chains for dimensional metrology, traceable length measurement, and establishing reference lengths for laboratory and workshop measurements.
Related standards
ISO 3650:1978 (withdrawn — replaced by the 1998 edition); ISO 3650:1998/Cor 1:2008 (technical corrigendum). Normative and related GPS standards commonly referenced with this document include ISO 1101 (geometrical tolerancing), ISO 14253‑1 (inspection by measurement — decision rules) and ISO 1 (standard reference temperature for industrial length measurements). The standard is maintained by ISO/TC 213 (Dimensional and geometrical product specifications and verification).
