Описание (английский):

This method indicates only essential features ans should be used when it is not necessary to show the exact shape and details of the seals, for example in assembly drawings. The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of documentation. ISO 9222-2 deals with the detailed simplified representation.

Overview

EN ISO 9222-1:1995 (ISO 9222-1:1989) - Technical drawings - Seals for dynamic application - Part 1: General simplified representation - is a drawing standard adopted by CEN for the simplified depiction of dynamic seals on mechanical engineering drawings. It defines a compact, unambiguous way to show seals when the exact shape or lip configuration is not required (for example in assembly drawings or general arrangement documentation). Use of this standardized symbol reduces drawing clutter, speeds drafting, and avoids misinterpretation.

Key Topics and Requirements

When to use: Apply the general simplified representation when it is unnecessary to show the exact contour or lip details of a seal (assembly drawings, schematic layouts, catalog overviews).

Symbol format: Represent the seal by a square with a freestanding diagonal cross centered inside the square. The diagonal cross must not touch the square outlines.

Line work and scale:

Use the same visible-outline line thickness as other visible outlines on the drawing (line type A per ISO 128).
The seal symbol must be drawn to the same scale as the rest of the drawing.

Sealing direction: If direction matters, indicate it by adding an arrowhead to the diagonal cross (or specify direction by text). If direction is unimportant the basic square + cross is sufficient.

Exact contour option: If the true cross-sectional contour is required, show the true outline with a centered diagonal cross (cross not touching outlines).

Hatching: Avoid hatching in simplified representations. If necessary (e.g., more detailed catalogue illustrations), hatch all inserts and similar elements with continuous thin lines (line type B per ISO 128) or use blackening for clarity.

Consistency: To prevent misunderstandings, use only one kind of simplification (general or detailed) on a single drawing.

Practical Applications and Users

Who uses it:

Mechanical design engineers and CAD technicians
Drafting offices producing assembly or installation drawings
Technical illustrators and spare-parts catalog creators
Seal and component manufacturers preparing standardized documentation

Where it helps:

Assembly drawings, installation manuals, procurement documents
Product catalogs and parts lists where full seal geometry is unnecessary
Cross-disciplinary drawings where clarity and speed of interpretation are priorities
