ISO/TR 27165:2012 provides definitions for wall constructions of thermoplastics pipes intended to be used in pressure and non-pressure pipe applications. It takes into account as far as possible already existing definitions in published product standards and gives guidance for a common text when drafting new deliverables or revising existing ones.

Overview

CEN ISO/TR 27165:2012 is a Technical Report that provides standardized guidance for definitions of wall constructions in thermoplastics piping systems. It primarily targets thermoplastics pipes used in both pressure and non-pressure applications. The document consolidates and harmonizes existing definitions found in published product standards, aiming to create a unified language for industry professionals when drafting new standards or revising current ones.

Developed by CEN/TC 155 in collaboration with ISO/TC 138/SC 2, this guidance is crucial for manufacturers, designers, and regulatory bodies involved in plastic pipe systems, ensuring consistency in terminology related to pipe wall structures.

Key Topics

Wall Construction Definitions The report clarifies terms related to different pipe wall types such as:

Solid wall pipes: Made from one or more compounds with consistent mechanical ratings.
Multilayer pipes: Comprised of two or more layers with different materials or functions, including polymeric and metallic layers.
Structured wall pipes: Featuring profiled outer layers, foamed, or hollow intermediate layers for enhanced performance.

Material and Layer Types Detailed definitions cover materials used, including:

Base polymers and compounds.
Functional layers for mechanical strength or special purposes (e.g., oxygen barriers, UV resistance).

Coated Pipes Definitions include coated pipes with peelable external layers intended for pipe protection during handling.

Special Pipe Constructions

Double wall piping systems: Comprising primary and secondary pipes separated by an interstitial space for leakage detection and environmental protection.

Dimension Ratio Definitions Standard dimension ratios for metallic and polymeric layers ensure uniform evaluation of pipe wall thickness relative to diameter.

Applications

CEN ISO/TR 27165:2012 serves multiple practical applications in the thermoplastics piping industry:

Standardization of Product Development By providing clear terminology, manufacturers can ensure their pipes meet common expectations and regulatory requirements.

Design and Engineering Engineers use the uniform definitions for selecting appropriate pipe types and constructions based on application needs, such as pressure containment or chemical resistance.

Quality Assurance & Compliance Regulatory and certification bodies refer to this standard for evaluating product conformity and safety, especially for critical water, sewage, and industrial fluid transport systems.

Technical Documentation & Communication Enables uniform language in technical manuals, contracts, and marketing materials, reducing ambiguity during international projects.

Related Standards

ISO 472:1999 – Plastics Vocabulary, providing fundamental definitions relevant to plastics materials.

ISO 1043-1:2011 – Plastics Symbols and Abbreviated Terms, defining polymer types and characteristics.

Other CEN and ISO product standards for thermoplastic pipes, fittings, and valves establishing performance criteria often referencing terminology from ISO/TR 27165.

By adopting CEN ISO/TR 27165:2012, stakeholders in thermoplastics piping systems benefit from enhanced clarity, improved interoperability, and reinforced safety across pressure and non-pressure applications worldwide. This technical report is foundational for ensuring high standards in plastic pipe manufacturing, testing, and utilization.
