This document defines the requirements and test methods applicable to factory applied extruded polyethylene coatings for the external corrosion protection of ductile iron pipes according to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C. This document does not cover ductile iron pipes protected with thin PE sleeve. Special works at site like drilling, tapping etc. can influence the corrosion protection properties. Those job steps are intended to be included in the instructions of pipe saddle and accessory manufacturers and all other essential installation instructions. These instructions are not part of this document545.

This part of ISO 6259 specifies a method of determining the tensile properties of pipes made of unplasticized poly(vinyl chloride) (PVC-U), oriented unplasticized poly(vinyl chloride) (PVC-O), chlorinated poly(vinyl chloride) (PVC-C) and high-impact poly(vinyl chloride) (PVC-HI), and in particular the following properties: — the stress at yield; — the stress and the elongation at break.
