GF Piping Systems - System Specification - for PVC-U metric piping systems 1. Scope This specification covers requirements for the GF PVC-U Piping System intended for a wide range of applications including water, wastewater and effluent treatment as well as a wide range of chemical applications. The components of the PVC-U piping systems are in accordance with the following standards. 2. Basic System Data 2.1 Material Specification for Unplasticised Polyvinylchloride (PVC-U) PVC-U pipes, fittings and valves from GF Piping Systems shall be manufactured from unplasticised polyvinylchloride and are designed for 25 years of operation with water as medium (20°C). PVC-U has also an optimal chemical resistance against many mineral acids, bases and salt solutions. For detailed information, please refer to the list of chemical resistance provided by GF Piping Systems. The raw material used shall be material designed for use with pressure bearing piping systems with long term hydrostatic properties in accordance with EN ISO 15493, as supplied by GF Piping Systems. 2.2 Characteristics of PVC-U Material Characteristic Value Test Standards Density 1.38 g/cm3 ISO 1183-1 Tensile E-modules >2400 N/mm2 EN ISO 527-1 Charpy notched impact strength at 23° C >8 kJ/m2 EN ISO 179-1/1eA Charpy notched impact strength at 0° C >3 kJ/m2 EN ISO 179-1/1eA Vicat heat distortion temp.

GF Piping Systems 3. Pipes Pipes are made of PVC-U and processed according to the quality specifications and dimensions according to EN ISO 15493. Pipe formulation has been designed for an enhanced chemical resistance (content of CaCO3 < 3%), enhanced thermo stabilizer package etc. Processed pipes are straight and show a very low out-of-roundness. The wall structure is homogeneous and even. OD-tolerances surpass the requirements of ISO 15493 and are compatible with the fitting programme of GF Piping Systems for easy pre-assembly and minimized gaps. For highly demanding applications in the chemical industry, the application of pressure rating SDR 9 pipes and PN 16 fittings is strongly recommended for OD ≤110 mm. Any installation should follow the GF Piping Systems installation guidelines for industrial piping and the guidelines issued by the DVS. Approved pipes comply with the corresponding quality specifications of DIN Certco ZP 1.1.1. 4. Fittings All PVC-U fittings manufactured by GF Piping Systems are suitable for solvent cementing, with dimensions and tolerances in accordance with EN 1452-1 & 3 and EN ISO 15493. All the requirements of those standards must be fulfilled. All threaded connections shall have pipe threads in accordance with the requirements of ISO 7-1. 4.1 PRO-FIT Fittings in PVC-U All PRO-FIT PVC-U fittings manufactured by GF Piping Systems (elbows 45° and 90°, tee equal, reducing bushes, and unions) have a special combination of spigot and socke connection and are available in metric sizes from d20-63. The PRO-FIT fittings have a 45° angle marking as well as integrated marking for vertical mounting integrated length marking on the spigots indicate the insertion depth. Reducing bushes shall offer the possibility of a spigot and cemented socket connection on each side of the fitting. System specifications PVC-U metric Schaffhausen, June 2018 Page 3 / 26

GF Piping Systems 4.2 Product Identification All parts are identified as specified by EN ISO 15493: - Manufacturer’s logo - Dimension (without the letter “d”) - Material - Nominal pressure (PN) - Permanent stamped (impressed) date with year and production lot 4.3 Packaging and Labelling The packaging must ensure that the fittings are not damaged during transportation. Packaging and labelling must meet the following requirements: • Identification of the content, in type, quantity and product details • Information about standards and approvals covered by the product • Content of the label has to accomplish legal requirements • Labels must be EAN coded for automatic identification • Comply to GF standards as well as to international standards such as ISPM15 5. Accessories 5.1 Flanges Backing flanges in metric sizes DN15-400 shall be designed according to EN ISO 15493, in a thermo plastic-oriented design, consisting of 100% glass fibre reinforced polypropylene, PP-GF30, graphite black and UV stabilized. These flanges are manufactured in a seamless technology injection moulding process by GF Piping Systems. The backing flange shall be optimised with a V-groove in the inner diameter to ensure an evenly distributed force on the thermo plastic flange adapter. The backing flanges shall be marked with dimension, PN-value, standards, brand and lot number. Connecting dimensions metric according to ISO 7005, EN 1092; Bolt circle diameter PN 10; Inch: ANSI B 16.5, BS 1560; class 150. Alternatively backing flanges in metric sizes DN15-400 shall be designed according to EN ISO 15493, consisting of unplasticised polyvinyl chloride (PVC-U), in a thermo plastic-oriented design. The backing flanges shall be marked with dimension, PN- value, standards, brand and lot number. Connecting dimensions metric according to ISO 7005, EN 1092; Bolt circle diameter PN 10; Inch: ANSI B 16.5, BS 1560; class 150. System specifications PVC-U metric Schaffhausen, June 2018 Page 4 / 26
