ISO 1452-2:2009

Overview

ISO 1452-2:2009 - Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure - Unplasticized poly(vinyl chloride) (PVC‑U) - Part 2: Pipes - specifies the characteristics and test parameters for solid‑wall PVC‑U pipes used in pressured water and sewage systems. It applies to extruded pipes with or without sockets (integral or separate) intended for buried and above‑ground use, including potable water, services, mains and pressure drainage/sewerage.

Key topics and technical requirements

• Material requirements
  • Pipe material conforms with ISO 1452‑1.
  • Density at 23 °C: 1 350–1 460 kg/m³ (measured to ISO 1183‑1).
  • Minimum Required Strength (MRS): ≥ 25 MPa, verified per ISO 1452‑1 procedures.
• Temperature and pressure range
  • Designed for potable water under pressure up to and including 25 °C.
  • Applicable for water and wastewater up to and including 45 °C (with selection guidance for 25–45 °C).
  • Covers a range of pipe sizes and pressure classes; Annex A provides allowable operating pressures.
• Geometrical and dimensional controls
  • Nominal outside diameters, mean diameters, wall thicknesses, tolerances and out‑of‑roundness measured per ISO 3126 and specified tolerances (see standard tables).
  • Requirements for pipe lengths, socket dimensions, and pipe ends for ring‑seal or solvent‑cement joints.
• Mechanical and physical tests
  • Resistance to internal pressure and long‑term hydrostatic performance per ISO 1167.
  • Impact strength, tensile properties (ISO 6259 series), longitudinal reversion (ISO 2505).
  • Opacity for above‑ground potable‑water pipes: max 0.2% visible light transmission (ISO 7686).
• Appearance and colour
  • Surface quality criteria; color rules: grey/blue/cream for water supply; grey/brown for drainage/sewerage (uniform through the wall).
• Ancillary requirements
  • Sealing rings, adhesives, performance requirements and marking/identification are specified.

Applications and users

• Practical uses:
  • Buried water mains and service pipes
  • Above‑ground conveyance inside/outside buildings
  • Pressure drainage and sewerage lines
• Who uses the standard:
  • PVC‑U pipe manufacturers, product designers and compounders
  • Water utilities, consulting engineers and specifiers
  • Installers, plumbing contractors and procurement teams
  • Test laboratories and conformity assessment bodies

Related standards

• ISO 1452 series: Part 1 (General), Part 3 (Fittings), Part 4 (Valves), Part 5 (Fitness for purpose)
• Test and properties standards: ISO 1167, ISO 3126, ISO 1183‑1, ISO 6259‑2, ISO 7686
• Joint/seal standards: EN 681‑1, adhesive test methods (ISO 7387‑1, ISO 9311‑1)
