European foreword
This document (CEN/TS 14541-2:2022) has been prepared by Technical Committee CEN/TC 155
“Plastics piping systems and ducting systems”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document, together with Part 1 of the EN 14541 series, supersedes CEN/TS 14541:2013.
The EN 14541 series consists of the following parts under the general title Plastics pipes and fittings -
Utilisation of thermoplastics recyclates:
— Part 1: Vocabulary;
— Part 2: Recommendations for relevant characteristics (this document).
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
The EN 14541 series is intended to give recommendations to the value chain of thermoplastics piping
systems to stimulate the use of thermoplastics recyclates as defined in the European circular economy
policy.
Part 1 of the EN 14541 series defines the relevant terms and definitions related to the use of
thermoplastics recyclates in thermoplastics piping systems.
This document (part 2 of the EN 14541 series) is a CEN Technical Specification in which
recommendations are given for product standards related to the relevant characteristics for defining
(e.g. fingerprinting) commonly used thermoplastics recyclates intended to be used in thermoplastics
piping systems.
This document is intended to support specification writers of product standards within CEN TC 155 in
defining the relevant characteristics for thermoplastics recyclates (PVC-U, PVC-C, PE, PP, and ABS) to be
specified in the relevant product standards for use in thermoplastics piping systems. The product
standards should specify relevant characteristics and applicable tolerances to be included within the
agreed specification. For a specific application, specification writers may specify additional
characteristics.
This document introduces the Cracked Round Bar (CRB) test for slow crack growth resistance of
recycled PE, PP and PVC-U material.
This document is extended, compared with the CEN/TS 14541:2013, and covers next to PE, PP and
PVC-U also PVC-C and ABS.
This document is not intended as a standalone specification for use of recyclates in plastic piping
systems.
Different CEN Technical Committees are dealing with recycled Plastics. In particular CEN/TC 249
"Plastics". 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 touching recycling are e.g. ISO 15270 [7] and Waste Framework Directive [8].
1 Scope
This document provides guidance and information for drafting product standards to specify
characteristics and test methods for the utilization of thermoplastics recyclates (PVC-U, PVC-C, PE, PP,
ABS) in pipes, fittings and ancillaries for thermoplastics piping systems.
This document covers recyclates with an agreed specification from all sources.
NOTE 1 This document does not cover characteristics for reworked material.
NOTE 2 This document does not cover recycling processes (e.g. chemical or mechanical).
NOTE 3 This document does not define if recycled material can be used in a specific application. The possible
use of recyclates will be defined in the applicable product standard.
This document provides guidance about the relevant characteristics to be included in the agreed
specification for recyclates.
This document is applicable without prejudice to any existing legislation.
For the recycling process, the transport, the testing and the use of thermoplastics recyclates, National
and/or European regulations (e.g. hygienic aspects) can apply.
NOTE 4 For example, threshold levels for substances of very high concern (SVHC) as defined in the REACH-
legislation which can possibly be present in thermoplastic recyclates.

5 Guidance for agreed specification and quality plan of the supplier
5.1 General
The conditions for the use of recyclates should be defined in the applicable product standard.
This document provides recommended characteristics (see Clauses 6.2, 6.3, 6.4, 6.5 and 6.6) to be
considered for inclusion in the agreed specification(s) of a product standard. Additional characteristics
may need to be considered depending on the application.
The product standard should define the documentation that should be used to cover all deliveries and
to verify conformity with the agreed specification.
Depending on the application of the products, different requirements regarding the use and/or quality
control of reworked material and recyclates may apply.
5.2 Agreed specification
A specification should be agreed, between the supplier of the recyclate and the manufacturer, for each
grade of thermoplastic recyclates.
The following minimum information should be included in the agreed specification:
— the relevant characteristics as specified in the referring product standard;
— the values, units and tolerances for each characteristic;
— the defined batch size(s);
— the agreed sampling procedures, sample preparation methods, and testing frequencies.
NOTE Guidance on sampling procedures, sample preparation and testing can be found in CEN/TS 16010 [5]
and CEN/TS 16011 [6].
When drafting an agreed specification, the following should be considered:
— the recycling process and sources of the material being mindful of risk of impurities;
— the processing of the material into the end product;
— the required characteristics of the end product;
— possible limitations of sources for the recyclable material;
— the intended dosage level of the material.
5.3 Quality plan of the supplier
It is recommended that the quality plan of the supplier of recyclates is not less stringent than the
relevant requirements of EN ISO 9001 [9].
5.4 Reworked material
In EN 14541-1, reworked material is defined as “plastics material from rejected unused products or
trimmings capable of being reclaimed within the s
