EN 15345:2007 – Plastics – Recycled Plastics – Characterisation of Polypropylene (PP) recyclates
1 Scope
This European Standard defines a method of specifying delivery conditions for Polypropylene (PP) recyclates.
It gives the most important characteristics and associated test methods for assessing a single batch of PP recyclates intended for use in the production of semi-finished/finished products.
It is intended to support parties involved in the use of recycled PP to agree on specifications for specific and general applications.
This standard does not cover the characterisation of plastics wastes. See EN 15347.
This standard is applicable without prejudice to any existing legislation.

4 Characteristics of PP recyclates
A single batch is the quantity of recyclate that has homogenous characteristics within the specified tolerances.
The characteristics of PP recyclates, given in Table 1, are divided into two types:
Required characteristics needed to characterize PP recyclates in general and required for specified recyclates.
Optional characteristics needed to characterize PP recyclates according to customer specifications and applications.
NOTE Polypropylene, or polypropylene-containing plastics wastes may contain a variety of propylene polymers such as homo- and co-polymers, isotatic, syndiotatic and atatic, and be with or without fillers, fire retardants etc. The performance of recyclates derived from such wastes will depend on the relative proportions of these components. In order to be described as recycled polypropylene, the recyclate must contain polypropylene as the most important polymeric component.
These characteristics shall be assessed by using the test methods given in Table 1. Where possible, the supplier should provide information on the original application of the material.
A Certificate of Analysis, providing the test results for each batch of recyclate shall be provided by the supplier to the purchaser on 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.
