Plastics piping systems for water supply -- Unplasticized poly(vinyl chloride)(PVC-U) and oriented PVC-U (PVC-O) -- Guidance for installation
Plastics piping systems for water supply -- Unplasticized poly(vinyl chloride)(PVC-U) and oriented PVC-U (PVC-O) -- Guidance for installation
ISO/TR 4191:2014 gives recommended practices for installation of unplasticized poly(vinyl chloride) (PVC-U) and oriented unplasticized poly(vinyl chloride) (PVC-O) pipes, fittings, valves, and ancillaries when used in piping systems conveying water under pressure.
The recommendations are intended to give practical guidance of design and installation of piping systems incorporating pipes, fittings, valves, and ancillary equipment made from PVC materials and used for the following purposes: water mains and services buried in ground, waste water under pressure, and conveyance of water above ground for both outside and inside buildings, for the supply of water under pressure at approximately 20 °C (cold water) intended for human consumption and for general purposes.
ISO/TR 4191:2014 is also applicable to components for the conveyance of water up to and including 45 °C. For temperatures between 25 °C and 45 °C, Figure 1 of ISO 1452‑2:2009 applies.
In addition, recommendations are given for the connection to fittings, valves, and ancillary equipment made from materials other than PVC.

Cevni sistemi iz polimernih materialov za oskrbo z vodo - Nemehčan polivinilklorid (PVC-U) in orientiran PVC-U (PVC-O) - Navodila za vgradnjo
Tehnično poročilo ISO navaja priporočene prakse za namestitev cevi, fitingov, ventilov in pomožne opreme iz nemehčanega polivinilklorida (PVC-U) in orientiranega nemehčanega polivinilklorida (PVC-O), kadar se uporabljajo v cevnih sistemih za prenos vode pod tlakom.
Priporočila so namenjena podajanju praktičnih smernic za projektiranje in namestitev cevnih sistemov, ki vključujejo cevi, fitinge, ventile in pomožno opremo iz PVC-ja in se uporabljajo za naslednje namene:
– vkopane vodovode;
– odpadne vode pod tlakom;
– nadzemni prenos vode zunaj in znotraj stavb;
za dovajanje vode pod tlakom, ki ima približno 20 °C in je namenjena za pitno vodo in splošne namene.
Tehnično poročilo se uporablja tudi za komponente za prenos vode s temperaturo do vključno 45 °C. Za temperature med 25 °C in 45 °C se uporablja slika 1 iz standarda ISO 1452-2:2009.
Poleg tega so podana priporočila za priklop na fitinge, ventile in pomožno opremo iz drugih materialov, ne iz PVC-ja.
