Описание (английский):

This document specifies the recommended proportions for the symbols used in technical product documentation. It gives recommended dimensions based on the grid related to the line width to be used. This document does not apply to symbols used in process plant documentation, which are covered in ISO 81714-1. The proportions of the symbols are based on the standard heights of lettering given in ISO 3098-1.

Overview

ISO 7083:2021 - Technical product documentation - Symbols used in technical product documentation - Proportions and dimensions specifies recommended proportions and dimensions for symbols used in technical product documentation. The standard defines sizes based on a grid related to the line width and aligns symbol proportions with the standard lettering heights given in ISO 3098-1. It excludes symbols for process plant documentation (covered by ISO 81714-1) and documents the validated symbol set produced under ISO/TC 10 and ISO/TC 213.

Key Topics and Requirements

Scope and purpose: Standardizes symbol proportions and recommended dimensions to ensure consistent, legible technical drawings and CAD outputs.

Relationship to lettering: Proportions are based on standard lettering heights in ISO 3098-1; symbols on a drawing should use the same height, line width and lettering type as the dimensioning and indications.

Lettering types and dimension tables:

Lettering type A (Table 1): example frame heights (H) 7, 10, 14, 20, 28, 40 mm; character heights (h) 3.5 to 20 mm; line widths (d) 0.25 to 1.4 mm.
Lettering type B (Table 2): example frame heights 5 to 40 mm; character heights 2.5 to 20 mm; line widths up to 2 mm.

Grid and line-width rules: Symbol configurations are depicted on a grid with spacing equal to the line width. Recommended dimensions and proportions are expressed relative to that grid.

Tolerance and frame spacing: Widths of tolerance indicator frames and compartment spacing are specified; vertical stroke distances to inscriptions must be at least twice the line width, with a minimum of 0.7 mm.

Production methods: Symbols may be produced digitally, hand-drawn (with rules), stenciled, or transferred - but must comply with the standard proportions.

Symbol validation and registration: New symbols follow a submission and validation process via ISO/TC 10; approved symbols receive registry numbers and are published on the ISO Online Browsing Platform.

Practical Applications and Who Uses ISO 7083:2021

Technical drafters and CAD engineers - to create standardized, unambiguous drawings and templates.

Manufacturers and design offices - for consistent documentation across part drawings, assembly instructions and specification sheets.

Technical illustrators and documentation specialists - to ensure legibility and interoperability of symbol graphics.

Quality assurance and compliance teams - to verify drawings meet international documentation standards.

Standards developers - for harmonizing new symbols before registration.

Typical uses include symbol libraries for CAD systems, drawing templates, technical manuals, and product specifications where consistent symbol size, proportion and spacing are important.

ISO 128, ISO 129, ISO 1101, ISO 286-1 - referenced symbol sets and geometry/layout conventions

ISO 7083:2021 is essential for anyone producing or regulating technical product documentation who needs consistent, standards-compliant symbol proportions and dimensions.
