In comparison with the previous version, the following technical modifications have been introduced:
— PE 100-RC type materials with enhanced resistance to slow crack growth have been added.
— Annex A now discusses the performance of this type of material and gives additional information for non-
conventional installation techniques.
— The size range has been increased to 800 mm diameter.
— Test methods have been updated.
— New test methods have been added for PE 100-RC materials.
