1 Scope This standard specifies mainly the method to be used when describing test specimen location and notch orientation for the testing and reporting of impact tests on welded butt joints. This standard applies to impact tests on metallic materials in all forms of product made by any fusion welding process. It is used in addition to EN 10045-1 and includes test specimen denomination and additional reporting requirements.

2 Normative reference This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 10045-1 Metallic mater2al.s - Charpy impact

test - fid 1: %t method

3 Principle Impact testing shall be in accordance with EN 10045-1. The test temperature, location, type and size of test specimen, and notch orientation shall be in accordance with the relevant application standard. In addition to the requirements of EN 10045-1, the notch position may be located by macroetching.

4 Method of denomination 4.1 Lettering system The denomination is based on a lettering system to describe the type, location and notch orientation and a numbering system to show the distance (in millimetres) of the notch from reference lines (RL). The method of denomination is shown in tables 1 and 2. The test specimen shall be taken from the welded joint such that its longitudinal axis is at right angles to the weld length. 4.2 Characters The denomination comprises the following characters :

1st character U : Charpy U notch, V : Charpy V notch;

2nd character

3rd character

4th character

5th character

Page 3 EN 876 : 1995

W : notch in the weld metal ; the reference line is the centre line of the weld at the position of the test specimen, H : notch in the heat affected zone; the reference line is the fusion or the joint line (notch wiìi include HAZ); S : notched face parallel to the surface 11, T : notch through the thickness; a : the distance of the centre of the notch from the reference line (if a is at the centre line of the weld, a = O which should be recorded); b : the distance from the weld joint face side2) to the nearer face of the test specimen (if b is at the surface of the weld,

recorded). b = O Which Should be

4.3 Additionai information In cases where this simple denomination does not sufficiently define the location or notch orientation, a sketch referring to the weld procedure should be provided.

5 Examples of denomination Examples of denominations are given in tables 1 and 2 and figure 1.

6 Examination The test specimens designated by this standard shall be tested in accordance with EN 10045-1.

7 Wst report The test report shall include the following information in addition to that given in EN 10045-1 :

- reference to this standard; - test specimen denomination; - sketch if required; - type and dimensions of imperfections observed; - other information as required by the application standard and/or by agreement between the contracting parties.

An example of a typical test report is given in annex A.

1) This orientation is equivalent to the denomination ‘surface notch’ used in fracture mechanics testing. 2) In the case of double V, K or similar welds, the face side is the side which contains the larger width of the weld or from which the welding energy was first applied.
