ISO 13272:2026

Overview

ISO 13272:2026 sets out the specifications for plastics piping systems used in non-pressure underground drains and sewers, focusing particularly on manholes and inspection chambers. The standard applies to products made from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifiers (PP-MD), and polyethylene (PE). These components are intended for installation in traffic areas and underground (outside buildings), accommodating a maximum installation depth of 6 meters from ground level to the invert of the main channel. Key application areas include wastewater, foul and domestic wastewater, and surface water drainage systems.

This comprehensive standard ensures that products meet uniform definitions, material requirements, geometrical dimensions, mechanical and performance criteria for safe and durable underground installation. Although the focus is on traffic areas, products compliant with ISO 13272:2026 are also suitable for non-traffic locations.

Key Topics

• Scope and Limitations

  • Covers circular manholes and inspection chambers up to a 6 m installation depth
  • Applicable in both traffic and non-traffic underground wastewater systems

• Material Requirements

  • Specifies the use of PVC-U, PP, PP-MD, and PE for bases, risers, cones, telescopic adaptors, and sealing ring retaining components
  • Allows use of non-virgin (recycled and reprocessed) materials under defined conditions

• Component Definitions

  • Manhole: Provides both equipment and human access to drain/sewer systems
  • Inspection chamber: Access for inspection and cleaning equipment only
  • Base, Riser, Cone, and Telescopic Parts: Functional components defined with clear performance and installation specifications

• Geometrical and Mechanical Characteristics

  • Sets minimum and maximum values for diameter, wall thickness, and tolerances
  • Mechanical requirements such as ring stiffness, impact resistance, and structural integrity under load

• Performance Assessment

  • Ensures watertightness, load-bearing capacity, and durability
  • Testing methods and parameters for each product category and joint type

• Safety and Marking Requirements

  • National regulations on safety and man-entry must be observed
  • Mandatory product marking and supporting documentation for traceability and compliance

Applications

The specifications outlined in ISO 13272:2026 ensure that manholes and inspection chambers:

• Enable safe and reliable access for maintenance, inspection, and cleaning of underground drainage and sewer systems
• Maintain integrity under vehicular and static traffic loads in roadways, parking lots, and similar locations
• Support installation in areas with variable groundwater conditions (up to 5 meters above invert as declared by the manufacturer)
• Provide flexibility in assembly, including single-unit (factory-assembled) or site-built systems, with clear guidance on component jointing (e.g., elastomeric seals, adhesive, welding, or mechanical methods)

This standard aids manufacturers, civil engineers, contractors, and municipal planners in selecting and installing compliant piping system access components that contribute to safe, efficient, and sustainable underground drainage infrastructure.
