Technical drawings - Seals of dynamic application - Part 2: Detailed simplified representation (ISO 9222-2:1989)

In contrast to the general simplified representation of part 1, this method shows more details of a seal, for example the configuration of lips. It should also be used when it is not necessary to show the exact shape and details of the seals, for example in assembly drawings. Elements and examples of this representation mode are given in tables and figures.

Dieser Teil von ISO 9222 legt Regeln für die detaillierte Darstellung von verschiedenen Dichtungen fest. Diese Darstellung ist anzuwenden, wenn es nicht nötig ist, die genaue Form und die Einzelheiten der Dichtungen zu zeigen, z. B.in Zusammenbau-Zeichnungen.

La présente partie de l'ISO 9222 prescrit une représentation simplifiée particulière de divers joints d'étanchéité. Il convient d'utiliser cette représentation lorsqu'il n'est pas nécessaire de montrer la forme exacte et les détails des joints d'étanchéité, par exemple dans des dessins d'assemblage.

Overview

EN ISO 9222-2:1994 / ISO 9222-2:1989 defines a method for the detailed simplified representation of seals used in dynamic applications on technical drawings. Unlike the more general symbol set in Part 1, this part prescribes how to show additional seal details (for example lip configuration) while still avoiding full, exact geometric depiction. The standard is intended for use where precise contour detail is unnecessary - typically in assembly drawings, catalogues and user manuals.

Key topics and requirements

• Scope: Applies to seals for dynamic applications (rotary, reciprocating and translational) where a more detailed but still simplified graphic is appropriate.
• Single representation rule: To avoid confusion, only one kind of simplification - either the general simplified (Part 1) or this detailed simplified method - should be used on any one drawing.
• Elements of representation: The standard defines basic graphic elements (see Table 1), for example:
  • Long continuous lines for static (fixed) elements and generating lines of sealing surfaces.
  • Diagonal or short lines to indicate dynamic sealing lips, dust lips, wipers and sealing direction (optional arrowheads).
  • Symbols for contactless seals (e.g., labyrinth-type T/U symbols).
• Placement convention: Seals are depicted in the drawing space above the axis.
• Illustrative tables and figures: Detailed simplified representations and examples are provided for common seal types (tables 2–4 and figures 1–5), including rotary shaft lip seals, piston rod seals, U‑cups, V‑rings, packing sets and labyrinth seals.

Practical applications and users

Who uses ISO 9222-2:

• Mechanical design engineers and CAD technicians creating assembly and installation drawings.
• Technical illustrators producing equipment catalogues, manuals and prospectuses.
• Seal manufacturers and suppliers for standardized product illustrations.
• Quality, procurement and maintenance teams relying on consistent drawing conventions.

Benefits:

• Consistency across technical documentation and supplier literature.
• Clarity of function (sealing direction, static vs dynamic elements) without over-detailing.
• Time savings compared with full-profile drawings while reducing misinterpretation.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 9333-2 was prepared by Technical Committee lSO/TC 10,

Introduction
IS0 9222 provides rules for the simplified representation of seals.
The principle of drawing practice is to depict the object to scale using lines. In
simplified representations, only essential features are shown, preferably in outline (in
order to save time and effort).
The degree of simplification depends on the kind of object represented, the scale of the
drawing and the purpose of the documentation. This means that either a general
simplified representation or a detailed one may be used. A detailed representation
shows more details of a seal, for example the configuration of lips.
In order to avo id misunde rstandings, only one kind of simplification, either general
the
or the detailed si mplif ied representation, shou Id be used on a drawing.
