Overview

SIST EN ISO 6412-3:2018 is an international standard developed by CEN that specifies the simplified representation of terminal features in ventilation and drainage pipeline systems for technical product documentation. Part of the broader ISO 6412 series, this standard focuses on providing clear and consistent graphical symbols and simplified views for components such as scuppers, air pipes, ventilator cowls, and directional vanes in technical drawings. The aim is to facilitate effective communication among engineers, designers, and construction professionals by standardizing how these pipeline terminal features are depicted in orthogonal projection views.

Key Topics

• Scope
  Defines simplified graphical representations for terminal features of ventilation and drainage systems in pipelines to ensure uniform documentation.

• Design and Representation Principles
  Emphasizes combination of simplified piping symbols with graphical elements such as actuators or pipes, following general rules set out in ISO 6412-1.

• Simplified Orthographic Views
  Provides two orthographic projections (front and top views) for each terminal feature, aiding clear and unambiguous interpretation of pipeline terminations.

• Terminal Features Covered
  Includes common ventilation and drainage components:

  • Scupper (with or without closing device and smell seal)
  • Air pipes (goose neck type)
  • Wall ventilator cowls
  • Mushroom ventilators (including screened versions)
  • Fixed and turnable ventilator cowls
  • Directional vanes within ducts and pipes

• Normative References
  Relies on ISO 5456-2 for orthographic projection methods and ISO 6412-1 for general pipeline representation rules, ensuring compliance with established technical drawing standards.

Applications

The standard is essential for:

• Mechanical Engineering Drawings
  Facilitates clear, simplified documentation of ventilation and drainage pipeline terminal features in mechanical design, plant engineering, and facility construction plans.

• Process Plant Documentation
  Enables standardized graphical communication critical in process plant layouts, maintenance manuals, and commissioning documentation.

• Pipeline Component Design
  Assists manufacturers and engineers in accurately documenting terminal features to meet regulatory requirements and improve interoperability.

• Technical Training and Education
  Provides a reference framework for teaching simplified representation techniques in technical drawing curricula related to HVAC and drainage systems.

By adhering to SIST EN ISO 6412-3:2018, organizations improve clarity and reduce interpretation errors in construction and maintenance projects involving ventilation and drainage pipelines.

Related Standards

• ISO 6412-1: General Rules for Simplified Representation of Pipelines
  Covers foundational principles and orthogonal representations applicable across the ISO 6412 series.

• ISO 5456-2: Orthographic Projection Methods
  Details standard projection techniques used to create front and top views, foundational for the representations in EN ISO 6412-3.

• ISO 128: Technical Drawings – General Principles of Presentation
  Provides overarching guidelines on standardized drawing presentations complementing pipeline documentation.

• ISO 5455: Scales for Technical Drawings
  Supports accurate scaling of simplified representations in technical documentation.

Keywords

Technical product documentation, simplified pipeline representation, ventilation terminal features, drainage system components, pipeline technical drawings, ISO 6412-3, ventilation and drainage symbols, orthographic projection, mechanical engineering standards.
