Overview

ISO 6412-3:2017, "Technical product documentation - Simplified representation of pipelines - Part 3: Terminal features of ventilation and drainage systems," specifies standardized, simplified graphic representations for terminal features of ventilation and drain pipelines used in technical drawings. The standard defines orthographic views (front and top) for common terminal elements and explains how these simplified forms integrate with other drawing symbols to improve clarity and efficiency in documentation.

Key topics and requirements

  • Scope: Defines simplified representations for terminal features of ventilation and drainage in pipeline systems.
  • Orthographic projection: Views are given as front and above projections in accordance with ISO 5456-2 (projection methods).
  • Terminal features covered: Includes scuppers, scuppers with closing devices, scuppers with smell seals, air pipes (goose necks), wall ventilator cowls, mushroom ventilators (optionally with screens), ventilators with closing devices, fixed and turnable ventilator cowls (inlet/outlet), and directional vanes in ducts.
  • Representation rules: Simplified symbols are intended to show essential features only (outline form), with the degree of simplification depending on object type, drawing scale and documentation purpose.
  • Combination with symbols: The simplified representations may be combined with graphical symbols (for actuators, pipes, etc.); general rules and additional symbols are given in ISO 6412-1.
  • Normative references: ISO 5456-2 and ISO 6412-1 are normative references; related drawing standards such as ISO 128 and ISO 5455 inform presentation and scale.

Applications and users

ISO 6412-3 is useful wherever standardized pipeline terminal graphics improve communication and reduce drawing ambiguity:

  • Technical drafters and CAD technicians creating piping and HVAC drawings
  • Piping, plumbing and HVAC designers documenting ventilation, drainage and exhaust terminations
  • Process plant documentation teams producing consistent as-built and fabrication drawings
  • Manufacturers and fabricators using symbol libraries for shop drawings
  • Maintenance and facilities teams reading simplified schematics for inspection and servicing

Practical benefits include faster drafting, consistent symbol libraries across projects, clearer multidisciplinary coordination, and reduced misinterpretation on construction and maintenance documents.

Related standards

  • ISO 6412-1 - General rules and orthogonal representation for simplified pipeline drawings
  • ISO 5456-2 - Projection methods (orthographic representations)
  • Other relevant references: ISO 128 (drawing presentation) and ISO 5455 (scales)

Keywords: ISO 6412-3, simplified representation of pipelines, ventilation and drainage symbols, technical drawings, pipeline terminal features, orthographic projection, ISO pipeline standards, HVAC drawings.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO 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, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
