Introduction
This standards series is answering to the European Standardization Request M/584 .
European standardization deliverable(s) on quality assessment of plastic recyclates for use in products
are expected for: recycled polyethylene (rPE), recycled polypropylene (rPP), recycled polyethylene
terephthalate (rPET), recycled polyvinyl chloride (rPVC), recycled polystyrene (rPS) (including recycled
expanded polystyrene (rEPS) and recycled extruded polystyrene (rXPS)), recycled acrylonitrile-
butadiene-styrene (rABS).
How to use this standards series?
The characteristics are generic and cover the properties the converter needs at the entry of the converting
operation. The intention is that this standard series supports the establishment of first contact with
possible suppliers that could deliver this recyclate with or without compounding. The designation system
is intended to make a callout for the desired recyclate. After first contact, the specifications will be agreed
between recycler and converter. This is not part of this standards series.
This series is not intended for use as a specification system, and hence cannot be used as a means to
guaranty a certain recyclate quality to a buyer of plastic recyclates. Characteristics are specified in
Annex B of the polymer specific parts of this series, which provides typical values or a range as applicable.
The EN 18064 series can be used by:
— producers of specific products for material selection of recyclates to be used in their products;
— recyclers to produce recyclates that are suitable for certain product families/production
technologies.
The EN 18064 series covers:
Part 1: description of purpose of this series of standards and designation system
Parts 2-7: Polymer specific parts, with two informative annexes as follows:
In the Annexes A designatory properties are given;
In the Annexes B, product families are specified in combination with the (most) relevant converting
technologies. In these Annexes B, typical values are provided for the characteristics.
The purpose of the demand driven approach is to give customers guidance to choose the recyclates that
will be adequate to use in the product of choice that is going to be manufactured.

M/584 COMMISSION IMPLEMENTING DECISION of 1.8.2022 on a standardisation request to the European
Committee for Standardisation and the European Committee for Electrotechnical Standardisation as regards
plastics recycling and recycled plastics in support of the European Strategy for Plastics in a Circular Economy
EN 18064 series may be used in conjunction with:
— EN 18065, Recycled plastics — Classification by data quality levels for use and (digital) trading.
These standards (EN 18064, Part 1 through Part 7) are aligned with ISO/TC 61 material standards:
— EN ISO 10350-1 identifies specific test procedures for the acquisition and presentation of comparable
data for certain basic properties of plastics;
— EN ISO polymer specific standards for the preparation of test specimens and determination of
properties (see normative references of the polymer specific parts EN 18064, Part 2 through 7).
The EN ISO material standards for polymers provides the designation system (see Part 1 of the EN ISO
material standards-moulding and extrusion materials). For recycling, appropriate additional test
methods should be taken up from the relevant EN or ISO material standard.
NOTE 1 The relevant EN standards could be e.g. EN 15342, EN 15344, EN 15345, EN 15346, EN 15348 and
EN 18067.
NOTE 2 The basis of the designation system is described in the ISO/IEC Directives Part 2 (2021), C.3“Designation
system.” This designation system was designed for virgin polymers. The designation system described in this
document is applicable for recyclates is based on that system.
NOTE 3 EC regulations and Directives can also apply.
NOTE 4 Regarding packaging in food contact, see also European legislation e.g. EC 2023/2006 (GMP),
1935/2004, 10/2011 and 2022/1616 as amended.
1 Scope
This document provides characteristics and typical values for polystyrene (PS) recyclates intended for
groups of defined applications (the product families).
The characteristics and typical values for the different product families are derived from the performance
requirements of the products belonging to that family, including requirements for product manufacturing
processes where applicable.
This document applies to plastic recyclates intended to be used for the manufacturing of (intermediate)
products.
This document is intended to be used in conjunction with part 1 of this standard series, which describes
the designation system for plastic recyclates. The designation system allows comparison between
recycled and virgin material at the level of the polymer’s defined designatory properties.
NOTE 1 Examples of designations of plastic recyclates are given in Annex A.
NOTE 2 The selection of relevant properties for a product family is based on EN ISO 10350-1, extended with
specific properties related to plastic recyclates.

7 Designation of polystyrene (PS) recyclates
The principle for this designation system is given in EN 18064-1, the ISO/IEC Directives, Part 2, 2021,
and Annex A.
This designation provides a code describing how to declare characteristics and related typical values for
recyclate materials, intended to be used for a defined category group (product family), enabling effective
communication between supplier and purchaser of recyclate materials, based on the intended use
(product family in combination with the relevant production technologies).
Annex A provides designatory properties of polystyrene recyclates given in EN ISO 24022-1.
Under A.2.7 examples of designation of a polystyrene thermoplastic material are given.
Annex A
(informative)
Designatory properties polystyrene (PS) recyclates
A.1 Generic and additional designatory properties
The types of polystyrene plastics are differentiated from each other by a classification system based on
appropriate levels of the designatory properties (see EN ISO 24022-1) and the following additional
designatory properties related to polystyrene:
a) Vicat softening temperature;
b) Melt mass-flow rate (MFR);
and information about chemical structure, method of processing, important properties, additives,
colour, fillers and reinforcing materials. See EN 18064-1 block 1 – 5, based on EN ISO 24022-1.
A.2 Designation of polystyrene (PS) recyclates
A.2.1 General
The designation system for thermoplastics is based on the following standardized pattern, as shown in
Table A.1.

The designation consists of an optional description block, reading e.g. “Thermoplastics”, and an identity
block comprising the considerable International Standard number and an individual-item block. For
unambiguous designation, the individual-item block is subdivided into five data blocks comprising the
information.
For further information on this designation system please refer to EN 18064-1, EN ISO 24022-1 and
ISO/IEC Directives, Part 2, 2021, Annex C.
A.2.2 Data block 1
Data block 1 contains the polymer information and optionally the data quality level (DQL) indication of
the respective material.
In this data block, after the hyphen, polystyrene plastics are identified by the symbol “PS”, in accordance
with EN ISO 1043-1 and EN ISO 24022-1 as below.
Table A.2 — Code letters used for additional information in data block 1
Code letter Definition
G Polystyrene homopolymer (General Purpose), usually called GPPS.
Includes recyclates coming from expanded polystyrene (EPS) and extruded polystyrene
(XPS) foams after pelletizing
H Polystyrene impact polymer consisting of two (or more) phases of which one of
polystyrene G and rubber phases composed of polybutadiene or styrene-butadiene

rubber, added in situ (grafting), or physically blended with the propylene plastic matrix
M Mixtures of polystyrene G and H
E Expandable polystyrene consisting of GPPS impregnated with a blowing agent
F Expanded polystyrene based on EPS raw material
X Extruded polystyrene based on GPPS (General Purpose PS) raw material
For recyclate the letter “r” is added in front of the abbreviated term for the type of polymer, e.g. “rPS”.
NOTE Additionally to the abbreviation “rPS”, “PS-R” or “R-PS” or “PS (REC)” are used as well.
Furthermore, the data quality level (DQL) could be added to data block 1 after another hyphen. To reach
a certain data quality level, several characteristics shall be added to a technical data sheet of the material.
These characteristics are listed in EN 18065.
In terms of the designation system a higher number of the data quality level indicates a need for more
information from the supplier.
A.2.3 Data block 2
In this data block, information about the type of filler and/or reinforcing material is represented by a
single code-letter in position 1 and its physical form by a second code-letter in position 2, the code-letters
being as specified in Table A.3 (in accordance with EN ISO 1043-2). For the filler material, it is
represented by a two-code-letter in position 1.
Subsequently (without a space), the mass content may be given by a two-figure-number in positions 3
and 4. The first figure-number is presented by 0 and the second figure-number is the figure of the mass
content if the mass content of filler and/or reinforcing material is less than 10 %.
Mixtures of filler materials or forms may be indicated by combining the relevant codes using the sign “+”
within parentheses followed by the total filler content outside the parenthesis. For example, a mixture of
25 % glass fibres (GF) and 10 % mineral powder (MD) would be indicated by (GF+MD)35 or
(GF25+MD10).

The type of metal shall be identified by means of the relevant chemical symbol(s) after the mass content. For
example, steel whiskers may be designated “MEH05Fe”.
For the purpose of packaging or insulation applications, data block 2 could not be relevant and will
remain empty.
A.2.4 Data block 3
In this data block, information about the intended application and/or method of processing is given by a
code-letter in position 1, followed by additional code-letters about additives, supplementary information,
and other characteristics in positions 2 to 8. The code-letters of EN ISO 24022-1 used are specified in
Table A.4.
If no specific information is given on the method of processing, the letter X shall be used as the first code-
letter.

A.2.5 Data block 4
A.2.5.1 General
In this data block, information about the range of Vicat softening temperature is represented by a three-
figure code-number (see A.2.5.2) and the melt mass-flow rate by a two-figure code-number (see A.2.6).
The code-numbers are separated from each other by hyphens.
If a property in Block 4 is not specified the symbol '#' will be used instead.
EXAMPLE (Thermoplastics) EN ISO 24022-1 rPS-2, (GF25+MD10), MLN, #-12, where the symbol '#' indicates
unspecified Vicat softening temperature.
If a property value falls on or near a range limit, the manufacturer shall state which range will designate
the material. If subsequent individual test values lie on, or on either side of, the limit because of
manufacturing tolerances, the designation is not affected.
For recyclates broader ranges can be applicable than for virgin materials. Therefor for recyclates multiple
ranges can be declared in the designation:
EXAMPLE
—  Designation virgin: (Thermoplastics) EN ISO 24022-1 PS, (GF25+MD10), MLN, 085-12
—  Designation recyclate: (Thermoplastics) EN ISO 24022-1 rPS-2, (GF25+MD10), MLN, 085-12/24 (broader MFR
range)
NOTE Not all combinations of the values of the designatory properties might be possible for currently available
materials.
A.2.5.2 Vicat softening temperature
The Vicat softening temperature shall be determined in accordance with EN ISO 24022-2.
The possible values of the Vicat softening temperature are divided into five ranges, each represented by
a three-figure code-number as specified in Table A.5.
NOTE The Vicat softening temperature is not applicable for EPS.
