GOST 12970-67 PDF

Full title and description

GOST 12970-67 — "Таблички круглые для машин и приборов. Размеры" (Round plates for machines and devices. Dimensions). The standard specifies nominal sizes, hole arrangements and basic dimensional parameters for round identification/name plates used on machines and instruments.

Abstract

This standard establishes standardized external dimensions and basic dimensional tolerances for circular plates (nameplates/identification plates) intended for machines and devices, including two executions (styles), nominal diameters, recommended hole diameters and recommended plate thickness values for steel and other materials. It incorporates amendment notes that have been integrated into the published text.

General information

• Status: Document listed as active / in force in public standards catalogs (listed as "Действует" in current databases).
• Publication date: Approved 23 May 1967; set to enter into force 1 January 1969 (often shown as publication/use date 1969).
• Publisher: Originally issued by the USSR Committee of Standards, Measures and Measuring Instruments (state standards body). Contemporary reprints and commercial reproductions are distributed by national standards resellers.
• ICS / categories: Mechanical systems and devices — characteristics and construction; classification corresponds to 21.020 (mechanical systems and devices / characteristics and construction).
• Edition / version: Original designation GOST 12970-67 (with integrated amendments Nos. 1 and 2 noted in the published text; amendment references Amd. 4-70 and Amd. 5-80 appear in catalogues).
• Number of pages: Short standard — commonly published as a 2‑page document in commercial and archival copies.

Scope

Specifies standardized nominal diameters, two typical executions (styles) of round plates, locations and sizes of mounting holes, plate thickness recommendations (values given specifically for steel plates and guidance for other materials), and mass per thousand pieces for the listed sizes. The standard is intended for application where a standardized plate dimension is required for machine nameplates or identification markers.

Key topics and requirements

• Table of nominal diameters (D) and related dimensions D1, D2, thickness (s) and hole diameter (d) for two executions of round plates.
• Permitted deviations/tolerances for diameters and hole sizes (tolerances referenced to fit classes such as h14/H14 where specified).
• Recommended thicknesses for steel plates and note that thickness for other materials is by agreement with the purchaser.
• Allowance for producing plates without holes or with enlarged hole diameters when agreed with the customer.
• Example of conventional designation for a plate (e.g., "Табличка 16 ГОСТ 12970-67").

Typical use and users

Used by machine and instrument designers, manufacturers of nameplates and identification plates, procurement and supply departments, quality and compliance engineers, and technical documentation authors who require consistent plate dimensions for assembly, mounting and interchangeability. Also referenced by maintenance and repair organizations when replacing or ordering standard plates.

Related standards

Directly related to GOST 12969-67 (technical requirements for plates) and GOST 12971-67 (rectangular plates for machines and devices — dimensions), plus other standards covering marking, materials and finishing for identification plates; many catalogs list these standards together.
