This document specifies the general aspects of short glass fibre reinforced polyethylene (PE-sGF) piping systems, manufactured by the spiral cross winding method, which are used below ground for the conveyance of liquid fluids for the following industrial and agricultural uses: — chemical plants; — industrial sewerage engineering; — power engineering (cooling and general-purpose water supply); — agricultural production plants; — water treatment; — small hydraulic power plants (general-purpose water supply). In conjunction with the other parts of the ISO 22101 series, this document applies to PE-sGF pipes, fittings and their joints with each other, with other PE-sGF components, and to components from other materials intended for use under the following conditions: a) allowable operating pressure (PFA) up to and including 25 bar[1]; b) operating temperature of 20 °C as the reference temperature. NOTE For other operating temperatures, guidance is given in Annex A. Other application areas differing from those listed in the scope can be permitted if the requirements of this document and/or relevant national requirements are taken into account. Drinking water applications are outside the scope of this document. This document covers only PE-sGF using glass fibre with lengths comprised in the range between 3 mm and 5 mm. Components conforming to any of the documents listed in the Bibliography or to national standards, as applicable, can be used with components conforming to this document, provided that they conform to the requirements for joint dimensions and to the relevant requirements of this document. [1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

This document collects available data on combined chemical resistance of thermoplastic materials typically used to manufacture piping components for industrial applications, against fluids over a range of temperatures. The base thermoplastic materials covered by this classification are: Polyethylene PE NOTE 1 The PE considered in this document corresponds to PE-HD, with a minimum density value of 0,935 g/cm3 (e.g.: PE63, PE80, PE100, PE100-RC, PE-RT). Polypropylene PP (PP-R and PP-RCT, PP-H, PP-B) Polyvinyl chloride, unplasticized PVC-U Polyvinyl chloride, chlorinated PVC-C Polybutylene PB Acrylonitrile/butadiene/styrene ABS Polyvinylidene fluoride PVDF NOTE 2 This document considers homopolymer PVDF. Cross-linked polyethylene PE-X (PE-Xa, PE-Xb, PE-Xc) Ethylene chloro trifluoro ethylene ECTFE Polyamide, unplasticized PA-U (PA-U11, PA-U12) NOTE 3 This document focuses on PA-U11 and PA-U12 only, as these long chained PA-U are standardized according to ISO 16486-1; short chained (e.g. PA 66) and plasticized PAs are not used for monolithic plastic piping components. Polysulfone PSU Perfluoralkoxy PFA NOTE 4 Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. Polytetrafluoroethylene PTFE NOTE 5 Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. Polyphenylene sulphide PPS NOTE 6 PPS is new with regards to industrial application and chemical resistance issues; for this reason, manufacturers and end-users are advised to assess the chemical suitability of the material.

ISO 15494:2015 specifies the characteristics and requirements for components such as pipes, fittings, and valves made from one of the following materials intended to be used for thermoplastics piping systems in the field of industrial applications above and below ground: - polybutene (PB); - polyethylene (PE); - polyethylene of raised temperature resistance (PE-RT); - crosslinked polyethylene (PE-X); - polypropylene (PP). NOTE 1 Requirements for industrial valves are given in this International Standard and/or in other standards. Valves are to be used with components conforming to this International Standard provided that they conform additionally to the relevant requirements of this International Standard. This International Standard is applicable to either PB, PE, PE-RT, PE-X, or PP pipes, fittings, valves, and their joints and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: - chemical plants; - industrial sewerage engineering; - power engineering (cooling and general purpose water); - mining; - electroplating and pickling plants; - semiconductor industry; - agricultural production plants; - fire fighting; - water treatment; - geothermal. NOTE 2 Where relevant, national regulations (e.g. water treatment) are applicable. Other application areas are permitted if the requirements of this International Standard and/or applicable national requirements are fulfilled. National regulations in respect of fire behaviour and explosion risk are applicable. The components have to withstand the mechanical, thermal, and chemical demands to be expected and have to be resistant to the fluids to be conveyed.
