This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 155.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 14541-1:2026) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN enquiry.
This document will supersede EN 14541:2022.
— Title and scope amended: “Utilisation of thermoplastic materials in a circular economy”
— Clause 3.1 definition “virgin material” improved and notes amended
— Clause 3.2 definition “reworked material” and notes amended
— Clause 3.4 “post-consumer material” note added
— Clause 3.5 term “recyclate” changed in to “recycled material”
— Clause 3.8 term “mechanical recycling” changed in “physical recycling” and note added to clarify
types of physical recycling
— Clause 3.9 “chemical recycling” note added to clarify types of recycling
— Clause 3.16 New term “extraneous polymer” added
This document is part of the EN 14541 series, which consists of the following parts under the general title
Plastics pipes and fittings — Utilization of thermoplastic materials in a circular economy.
a) Part 1: Vocabulary (this document);
b) Part 2: Recommendations for relevant characteristics.
Introduction
The EN 14541 series is intended to give recommendations to the value chain of thermoplastics piping
systems to stimulate the use of recycled thermoplastics material (e.g. PVC-U, PVC-C, PE, PP, and ABS) as
defined in the European circular economy policy.
This part of the EN 14541 series defines the relevant terms and definitions relevant to the utilization of
thermoplastics materials in a circular economy thermoplastics material in thermoplastics pipes and
fittings. The commonly used terms and definitions are reviewed, and as much as possible aligned with
the practises within the thermoplastics pipes and fittings value chain and the vocabulary used in
European policy documents (e.g. circular economy, sustainability) and existing international standards.
Part 2 is a CEN/TS document in which recommendations are given about the relevant characteristics for
defining (e.g. fingerprinting) commonly used thermoplastics recycled material intended to be used in
thermoplastics pipes and fittings.
The CEN/TS 18116:2024 (Thermoplastics pipes and fittings - Design for recycling) specifies design for
recycling guidelines for thermoplastics pipes and fittings, used as construction products or used for water
supply to irrigation systems. The guidelines are developed to facilitate mechanical recycling but could
also be beneficial for chemical recycling.
CEN/TC 249 “Plastics” developed a series of CEN publications on “Plastics Recycling” which consists of:
EN 15343 [1], EN 15344 [2], EN 15345 [3], EN 15346 [4], CEN/TS 16010 [5] and CEN/TS 16011 [6].
Other documents relevant for recycling are e.g. ISO 15270 [8] and Waste Framework Directive [9].
1 Scope
This document specifies the general terms and definitions relevant to the utilization of thermoplastics
materials in a circular economy in pipes, fittings and ancillaries for both pressure and non-pressure
piping systems.
This document is intended to be used by specification writers in conjunction with CEN/TS 14541-2 [7]
when preparing normative documents under the scope of CEN/TC 155.

3.1
virgin material
plastics material that has not been subjected to use or processing other than that required for its initial
manufacture
Note 1 to entry: virgin material is based on fossil or bio-based sources
Note 2 to entry: Does not contain any reworked material or recycled material
Note 3 to entry: Sometimes also referred to as “primary material”
Note 4 to entry: It is understood that the addition of additives such as stabilizers and pigments is still resulting
into a virgin (plastics) material
