This document specifies: a) field of application; b) requirements for in line anti-vacuum valves; c) dimensional, the physico-chemical properties and the properties of general hydraulic, mechanical and acoustic design of in-line anti-vacuum valves DN 10 to DN 50; d) test method and requirements for verifying these properties; e) marking and presentation; f) acoustics. This document specifies the characteristics of in-line anti-vacuum valves DN 10 to DN 50 that are suitable for use in drinking water systems at pressures up to 1 MPa (10 bar) and temperatures up to 65 °C and for 1 h at 90 °C.

This document specifies a procedure for the eddy current test with an encircling test coil for measuring defects on the outer surface of seamless round copper and copper alloy tubes. NOTE The eddy current test method(s) required, together with the size range and acceptance level, are defined in the relevant product standard. The choice of the method for eddy current test: - with an encircling test coil on the outer surface according to prEN 1971-1; or - with an internal probe on the inner surface according to prEN 1971-2; is at the discretion of the manufacturer if there are no other agreements between the purchaser and the supplier.

This document specifies a procedure for the eddy current test with an internal probe for measuring defects on the inner surface of seamless round copper and copper alloy tubes. This document applies particularly for finned tubes with high fins according to EN 12452. NOTE The eddy current test method(s) required, together with the size range and acceptance level, are defined in the relevant product standard. The choice of the method for eddy current test: - with an encircling test coil on the outer surface according to prEN 1971-1 or - with an internal probe on the inner surface according to prEN 1971-2 is at the discretion of the manufacturer if there are no other agreements between the purchaser and the supplier. Especially for finned tubes according to EN 12452 with high fins, it is suggested to use eddy current test with internal probe as described in this document.

1.1 The purpose of EN 13480 is to define the requirements for design, manufacture, installation, testing and inspection of industrial piping systems and supports, including safety systems, made of metallic materials (but initially restricted to steel) with a view to ensure safe operation. 1.2 EN 13480 is applicable to metallic piping above ground, ducted or buried, independent of pressure.

This Part of this European Standard specifies the requirements for materials (including metallic clad materials) for industrial piping and supports covered by EN 13480-1 manufactured from of metallic materials. It is currently limited to steels with sufficient ductility. This Part of this European Standard is not applicable to materials in the creep range.
