This document specifies the requirements and test methods for plastics piping systems intended to be used for the renovation of underground gas supply networks. It is applicable to pipes and fittings, as manufactured, as well as to the installed lining system. It is not applicable to the existing pipeline or any sprayed coatings or annular filler. This document gives the general requirements…

This document, in conjunction with ISO 11299‑1, specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of gas supply networks. It applies to pipes and fittings, as manufactured, as well as to the installed lining system. It is applicable to polyethylene (PE) pipe of either solid wall single layer or co-extruded layer construction, which is…

This document, read in conjunction with ISO 11299-1, specifies requirements and test methods for pipes and fittings which are part of plastics piping systems installed as continuous pipes in the renovation of underground gas supply networks. It is applicable to polyethylene (PE) pipes of three different types: — PE solid wall single layered pipes (nominal outside diameter, dn), including…

Le présent document spécifie des méthodes par analyse en flux continu (CFA) pour le dosage des orthophosphates dans le domaine de concentrations en masse allant de 0,01 mg/l à 1,00 mg/l (P), et pour le dosage du phosphore total dans le domaine de concentrations en masse allant de 0,10 mg/l à 10,0 mg/l (P). La méthode comprend la digestion des composés organiques du phosphore et l'hydrolyse…

This document specifies continuous flow analysis (CFA) methods for the determination of orthophosphate in the mass concentration range from 0,01 mg/l to 1,00 mg/l P, and total phosphorus in the mass concentration range from 0,10 mg/l to 10,0 mg/l P. The method includes the digestion of organic phosphorus compounds and the hydrolysis of inorganic polyphosphate compounds, performed either manually…
