The standard is an updated new edition that now also allows installation lengths of up to 6 000 mm. The document applies to plastic filter pipes and solid-wall pipes made of PVC-U with nominal diameters of DN 100 to DN 200 with a trapezoidal thread for the construction of drilled wells for the extraction of groundwater. The standard has been prepared by DIN-DVGW-Gemeinschaftsunterausschuss NA 119-07-03-01 AA "Bauteile und Produkte für Bohrtechnik und Brunnenbau" ("Components and products for drilling technology and well construction") at DIN Standards Committee Water Practice (NAW).
