3 Terms and definitions, symbols, and abbreviations
For the purposes of this document, the terms and definitions in Iso 4437-1:2014 and the following apply.
4 Material
4.1 Compound for pipes
The pipes shall be made from virgin material or own reprocessible material from the same PE compound or a mixture of both materials. Reprocessible material from co-extruded pipes or from pipes reprocessed with the peelable layer attached shall not be used. Own reprocessible material from the base pipe of peelable-layer pipes can be used.
The compound(s) from which the pipes are made shall conform to ISO 4437-1:2014.
4.2 Compound for identification stripes
For pipes with identifications stripes, the compound used for these identification stripes shall be made from the same base polymer (PE) as one of the pipe compounds for which fusion compatibility has been proven.
4.3 Recyclable material
Recyclable material including reprocessable material obtained from external sources shall not be used.ISO 4437-2-2014 pdf free download.
