minimum lining thickness the test tension shall be 4 kV. For 1000
minimum lining thickness the test tension shall be 5 kV. The scanning electrode shall be passed over the surface of the lining being inspected with a continuous, relative movement not exceeding 300 mm/s. The electrode shall not be damaged and shall be in constant touch with the lining. For thicker linings, a higher test voltage may be used by agreement between the manufacturer and the purchaser. 5.4 Pipe ends Spigot end and internal socket profile (see Figure 1) shall be coated with one of the following: — epoxy lining in accordance with EN 14901; — polyurethane in accordance with this standard with a minimum lining thickness of 150 m; — zinc + bituminous finishing layer according to EN 545; — multilayer, e.g. of epoxy, PUR-Epoxy; — zinc-rich paint and epoxy.
