ONR 20513

This ONR lays down terms and definitions, nominal sizes, dimensions, requirements, tests and the quality control for solid-wall multilayer pipes (PP-ML) of reinforced polypropylene-compound or polypropylene-blends for buried gravity drainage and sewerage pipelines. Furthermore this ONR lays down terms and definitions, nominal sizes, dimensions, requirements, tests and the quality control for fittings of one polypropylene compound or of reinforced polypropylene-compounds or of polypropylene-blends for buried gravity drainage and sewerage pipelines. Pipeline systems which relate to ÖNORM EN 14758-1 or to ÖNORM EN 13476-1, -2 or -3 are not subject of this ONR. This ONR also serves as a basis for the procedure of proving the conformity of relevant products. This ONR is applicable for gravity drainage and sewerage systems used within the building structure (application area code "D") and outside the building structure (application area code "U"). The marking of both application area codes is done by means of "UD" on the pipeline components.
