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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directiveswww.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on

Introduction
In the present context, countries across the globe have been promoting and bringing in regulations to use
recyclates in different plastics processing techniques for conversion into variety of end products. In a few
countries, guidelines or regulations for use of mechanically recycled granules or pellets may be available
from the respective national standardization bodies.
The broad objectives of this document are:
— listing of important test methods, which will be useful for processing of mechanically recycled PP and
PE ([in granular or pellet form, abbreviated as PP (REC) and PE (REC));)];
— provide uniform guidelines to recyclers on testing &and characterization for issue of
Technicaltechnical specifications .
— facilitate plastics processors in selecting mechanically recycled granules or pellets based on test
report.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 5677:2022(E)

Testing and characterization of mechanically recycled
polypropylene (PP) and polyethylene (PE) for intended use in
different plastics processing techniques
1 Scope
This document specifies test methods for assessing important properties of mechanically recycled
polypropylene [PP (REC)] and polyethylene [PE (REC)] in granular or pellet form for use in conventional
plastics processing techniques.
General guidance is provided for determining the characteristics of PP (REC) and PE (REC), which can be
used at 100 % or in a proportion with standard (virgin) material grades available for processing on
machines such as injection moulding, blow moulding, types of extrusion techniques, etc.
This document intends to help plastics processors and end users who intend to use recyclates with
agreement on product specifications, as applicable.
Country specific health and food-safety and environment related regulations for use of plastics recyclates
are not in the scope of this document.
Mixture of recyclates of PP and PE is not in the scope of this document.
