Plastics - Recycled plastics - Characterization of poly(ethylene terephthalate) (PET) recyclates
This European Standard gives guidelines for the characterisation of poly(ethylene terephthalate) (PET) recyclates.
It gives the most important characteristics and associated test methods for assessing of PET recyclates intended to be used for the production of semi-finished/finished products. It is intended for use by the supplier and purchaser of such materials, to assist them in agreeing specifications.
A single batch of R-PET (recycled PET) is presumed to be a homogenous and representative sample of the material to be characterised.
This standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with WI 249551 - "Guidelines for the development of standards relating to recycled plastics.
Kunststoffe - Kunststoff-Rezyklate - Charakterisierung von Polyethylenterephthalat (PET)Rezyklaten
Diese Europäische Norm gibt Anleitungen zur Bestimmung der Eigenschaften von Polyethylenterephthalat (PET)Rezyklaten.
Die Norm nennt die wichtigsten Eigenschaften und führt die dazugehörigen Prüfverfahren für die Bewertung von PET-Rezyklaten auf, die für die Produktion von Halbzeugen/Fertigprodukten vorgesehen sind. Sie ist für die Anwendung durch Lieferant und Käufer derartiger Materialien vorgesehen, um ihnen bei der Erzielung einer Einigung zu Spezifikationen Unterstützung zu geben.
Eine Einzelcharge von R-PET (rezykliertes PET) ist die Menge an Rezyklat, von der angenommen wird, dass sie eine homogene und repräsentative Probe des zu charakterisierenden Materials ist.
Diese Norm wurde nach der Anleitung erarbeitet, die vom CEN zu Umweltaspekten und in Übereinstimmung mit prCEN/TR 15353, Kunststoffe - Kunststoff-Rezyklate - Anleitung für die Entwicklung von Normen für Kunststoff-Rezyklate, herausgebracht wurde.

EN 15348:2007 (E) 4 Foreword This document (EN 15348:2007) has been prepared by Technical Committee CEN/TC 249 “Plastics”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This standard is one part of a series of CEN publications on Plastics Recycling which is structured as follows:

EN 15348 Plastics — Recycled plastics — Characterization of poly(ethylene terephthalate) (PET) recyclates CEN/TR 15353 Plastics — Recycled plastics — Guidelines for the development of standards for recycled plastics According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
EN 15348:2007 (E) 5 Introduction Recycling of plastics waste is one type of material recovery process intended to save resources (virgin raw materials, water, and energy), while minimising harmful emissions into air, water and soil as well as any impacts on human health. The environmental impact of recycling has to be assessed over the whole life cycle of the recycling system (from the waste generation point to the disposal of final residues). To ensure that recycling constitutes the best environmental option for treating the available waste, some prerequisites should preferably be met: recycling scheme being contemplated should generate lower environmental impacts than alternative recovery options; existing or potential market outlets should be identified that will secure a sustainable industrial recycling operation; collection and sorting schemes should be properly designed to deliver recyclable plastics waste fractions fitting reasonably well with the available recycling technologies and with the (changing) needs of the identified market outlets, preferably at minimum costs to society. This standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with CEN/TR 15353, Plastics—Recycled plastics—Guidelines for the development of standards for recycled plastics. NOTE CEN/TR 15353 considers the general environmental aspects which are specific to the recycling process. It is often impossible to trace back each individual product at the end user stage and to check whether the product has been used correctly through its life.
Consequently products are out of industrial control for a period of time.
It is possible that during this period contamination with other materials may occur that could affect the product's suitability for recycling into the intended application.
EN 15348:2007 (E) 6 1 Scope This European Standard gives guidelines for the characterisation of poly(ethylene terephthalate) (PET) recyclates. It gives the most important characteristics and associated test methods for assessing PET recyclates intended to be used for the production of semi-finished/finished products. It is intended for use by the supplier and purchaser of such materials, to assist them in agreeing on specifications.
This standard is applicable without prejudice to any existing legislation. 2 Normative references The following referenced documents are indispensable for the application of this document.

The characteristics of PET recyclates, which shall be met for every batch (see ISO 3534-2) of PET recyclate are shown in Table 1, and are divided into two types:
EN 15348:2007 (E) 7 Required characteristics needed to characterise PET recyclates in general and required for all recyclates.
Optional characteristics needed to characterise PET recyclates according to customer specifications and applications. These characteristics shall be assessed by using the test methods given in Table 1 and detailed below.
A Certificate of Analysis, providing the test results for each batch of recyclate shall be provided by the supplier to the purchaser upon request.
To secure the legal use of the recyclate, the supplier shall provide the necessary information about the material composition of the recyclates, as specified by the purchaser. SAFETY PRECAUTIONS — WARNING: It is most important for safety reasons that personal protective clothing is used when applying solvents to the test specimen. The use of solvents in regard to application of this standard may be further controlled under National and/or regional legislation.
