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.

Overview
EN ISO 9222-2:1994 specifies the method for creating detailed simplified representations of seals used in dynamic applications within technical drawings. Developed by CEN and aligned with ISO 9222-2:1989, this standard offers guidance on depicting seals such as rotary shaft seals, piston rod seals, and various dynamic seals where increased detail (e.g., lip configuration) is necessary, without requiring the full complexity of an exact geometric form. This approach is especially useful for assembly drawings, technical documentation, and schematic representations where clarity and efficient communication are critical but exhaustive detail is not needed.
Key Topics
- Detailed Simplified Representation: Unlike the general simplified approach (EN ISO 9222-1), this method includes extra details such as the specific structure of sealing lips, wipers, and other distinguishing features important in dynamic applications.
- Drawing Principles: The representation uses standardized lines and symbols to distinguish static and dynamic sealing elements, dust lips, U-cups, V-rings, packing sets, and labyrinth seals.
- Standardization in Communication: By applying this standard, designers and engineers facilitate a universal understanding of seal layouts in mechanical engineering drawings, eliminating ambiguity and ensuring consistency.
- Tables and Figures: EN ISO 9222-2 provides practical examples, detailed tables, and illustrations to show how diverse seals should be depicted depending on their function and location.
Applications
EN ISO 9222-2:1994 is relevant across multiple engineering and manufacturing environments where dynamic seals are utilized and require visual documentation, including:
- Assembly Drawings: Efficiently conveys the salient features of seals during design, review, or assembly without unnecessary complexity.
- Component Catalogues and Manuals: Used in technical literature, user handbooks, and product catalogues to give clear, standardized visuals of parts.
- Mechanical Engineering: Supports the development, installation, and maintenance of hydraulic and pneumatic systems, pumps, compressors, and any equipment utilizing seals in dynamic settings.
- Procurement and Quality Assurance: Ensures that vendors, suppliers, and internal teams consistently interpret and specify seal types, aiding in accurate sourcing and inspection.
This standard is especially beneficial when exact seal geometry is not critical for the particular drawing’s purpose but where key elements and overall arrangement must be unmistakably communicated.

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.
