Standards
DIN 16961
DIN 16961 Thermoplastics pipes and fittings with profiled outer and smooth inner surfaces:
Part 1: Dimensions
Part 2: Technical delivery conditions
DIN 16961.1:2010-03 applies to thermoplastics pipes with profiled walls and smooth inner surfaces made from polyethylene (PE 63, PE 80, PE 100 and PE-HD), unplasticized polyvinyl chloride (PVC-U), polypropylene (PP), homopolymers and copolymers and to fittings made from these pipes. The dimensions and properties for thermoplastic pipes with profiled outer and smooth inner surfaces.
DIN 16961.2:2010-03 focuses on technical properties for profiled pipes made of PE-HD (high density polyethylene), PVC-U (unplasticized polyvinyl chloride), PP (polypropylene) homopolymers or copolymers.
AS/NZS 2566:1998
AS/NZS 2566:1998 Buried Flexible pipelines
Part 1: Structural design
Part 2: Installation
AS/NZS 2566.1:1998 sets out a practice for the structural design of buried flexible pipelines which rely primarily upon side support to resist vertical loads without excessive deformation. The interactive pipe/embedment structure is considered only in the transverse direction. Structural performance is predicted in the long-term for pipes in trenches and embankments but not for jacked or bored lines. For the purposes of this Standard, the long-term design basis is 50 years, to take account of creep and other time dependent effects. The equations used in this Standard apply to pipes with outside diameters equal to or greater than 75 mm, initial ring-bending stiffness equal to or greater than 1250 N/m/m and long-term ring-bending stiffness equal to or greater than 625 N/m/m.
This Standard provides methods and data for calculating the response of a pipe to loadings from—
- Soil;
- Superimpositions on the soil; and
- Both positive and negative internal pressures.
AS/NZS 2566.2:1998 specifies requirements for the installation, field testing and commissioning of buried flexible pipelines with structural design in accordance with AS/NZS 2566.1. These pipelines rely primarily upon side support to resist vertical loads without excessive deformation by adopting an elliptical shape.
AS/NZS 4131:2010
AS/NZS 4131:2010 Polyethylene (PE) compounds for pressure pipes and fittings
Part 1: Polyethylene (PE) compounds for pressure pipes and fittings
AS/NZS 4131:2010 specifies requirements for polyethylene compounds (PE80 and PE100) suitable for manufacturing polyethylene pipes and fittings for pressure applications. Minimum requirements are given for materials, additives and long term pressure performance.
AS/NZS 5065:2005
AS/NZS 5065:2005 Polyethylene and polypropylene pipes and fittings for drainage and sewerage applications
Part 1: Polyethylene and polypropylene pipes and fittings for drainage and sewerage applications
AS/NZS 5065:2005 specifies requirements for polyethylene (PE) and polypropylene (PP) pipes and fittings for sewerage and drainage applications, above and below ground, inside and outside of buildings, and is intended to be operating under gravity flow and the operating pressure is low. It includes requirements for both plain and structured wall pipes and fittings

ISO 9969:2007 Thermoplastics pipes – Determination of Ring Stiffness
Part 1: Thermoplastics pipes – Determination of ring stiffness
ISO 9969 is the international standard that specifies a test method for determining the ring stiffness of thermoplastics pipes having a circular cross section.
