ISO 25902-1 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 11, Titanium. Iso 25902 consists of the following parts, under the general title Titanium pipes and tubes-Non-destructive testing: Part 1: Eddy-current examination Part2:Ultrasonicexaminationforthedetectionoflongitudinalflaws @ ISO 2009 - All rights reserved onal Organization for Standardizatior INTERNATIONALSTANDARD ISO25902-1:2009(E) Titanium pipes and tubes Non-destructive testing Part 1: Eddy-current examination Scope This part of IsO 25902 specifies a method for the eddy-current examination, hereafter referred to as the "tubes". Titanium tubes are now used as steam surface condensers in steam-power plants, anatomic-power plants and desalination plants. Therefore, the quality of titanium tubes is very important and this is why the eddy-current inspection method was established. This method also applies to titanium alloy tubes. In this part of ISO 25902 the minimum wall thickness is 0,3 mm, the rectangular groove and the drilled hole are permitted as reference standards, as the outside diameter of the titan
