This document specifies a method for the estimation of the average grain size of copper and copper alloy products by ultrasound. This document can be applied for seamless round tubes as well as for flat products.This method can be used in place of test methods according to EN ISO 2624, mentioned in the relevant product standards. As reference method and in case of doubt the intercept procedure or planimetric procedure will be used.

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 1971-1or- with an internal probe on the inner surface according to prEN 1971-2is 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.

This Part of EN 10217 specifies the technical delivery conditions in two test categories for welded tubes of circular cross-section made of austenitic and austenitic-ferritic stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.NOTE Once this document is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EU, pressure equipment directive, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials.
