Overview
SIST-TP 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
SIST-TP 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 SIST-TP 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no longer
