EN 2003-010:20074 Introduction This standard is part of the series of EN metallic material standards for aerospace applications. The general organization of this series is described in EN 4258. 1 Scope This standard specifies t

17、he location of the test pieces and the analysis samples used for the determination of hydrogen content in titanium and titanium alloys products. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition ci

18、ted applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 4258, Aerospace series Metallic materials General organization of standardization Links between types of EN standards and their use. 3 General requirements 3.1 The hydrogen conte

19、nt of a product shall be determined in the delivery condition unless otherwise agreed between manufacturer and purchaser. 3.2 The test pieces shall be cut so as to avoid contamination. Clean cutting tools shall be used. Abrasive wheel cutting and cutting fluids are permissible provided they are appl

20、ied under controlled conditions. 3.3 Cutting of the hydrogen analysis sample by laboratory personnel shall be done as far as possible using clean dry cutting tools. At this stage, abrasive cutting and cutting fluids are to be avoided unless it can be demonstrated that the technique used does not sig

21、nificantly affect the analysis results. 4 Location of test pieces 4.1 General Since hydrogen is more highly concentrated in zones close to the surface, the location of the test piece shall ensure that an analysis sample representative of the product is taken at a defined location related to the prod

22、uct surface; or if that surface remains in the finished part it shall include the product surface. EN 2003-010:20075 4.2 Sheet and strip (thickness 6 mm) Test pieces shall be taken so as to include the total sheet or strip thickness, in accordance with Figure 1. Figure 1 Sheet and strip (thickness 6

23、 mm) 4.3 Plate (thickness 6 mm) Depending on the thickness of the plate the test pieces shall either: contain at least one product surface as shown in Figure 2; or include the total thickness of the plate. Figure 2 Plate (thickness 6 mm), forgings and castings 4.4 Bar for machining, bar for fastener

24、s, sections and wire 4.4.1 For products with a diameter or thickness 5 mm, the test pieces shall include the total thickness of the product. EN 2003-010:20076 4.4.2 For products with a diameter or thickness 5 mm, the test piece shall either: contain at least one product surface as shown in Figure 3;

25、 or include the total thickness of the product. Figure 3 Forging stock (diameter or thickness 100 mm), bar for machining, bar for fasteners, sections and wire 4.5 Forging stock For forging stock with a diameter or thickness 100 mm, the test pieces location shall be in accordance with Figure 3. For l

26、arger diameters or thicknesses, the test pieces location shall be agreed between manufacturer and purchaser. 4.6 Forgings and castings Unless otherwise required in the inspection schedule, the location of test pieces shall be in accordance with Figure 2. 4.7 Tubes For tubes with a wall thickness 5 m

27、m, the test pieces shall include the whole wall thickness. For larger wall thicknesses, the location of the test pieces shall be agreed between manufacturer and purchaser. 5 Analysis samples 5.1 Mass The analysis samples shall be taken from the test pieces. They shall have normally a mass of less th

28、an 1 g. 5.2 Cleaning The analysis samples shall be cleaned, degreased and dried. Immediately before analysis is carried out, the laboratory personnel shall ensure that the analysis sample has a clean metallic, surface.
