can be taken from the web, at a quarter of the total height Test pieces are taken from the sample as indicated in Figure A.3 For sections with inclined flanges, the inclined surface may be machined in order to make it parallel to the other surface © BSI 12-1998 11 Licensed Copy: Puan Ms Norhayati, Petroliam Nasional Berhad, 31 July 2002, Uncontrolled Copy, (c) BSI EN 10113-1:1993 Figure A.2 — Bars 1) For products with small dimensions (d or b # 25 mm) the test piece, if possible, consists of an unmachined full section of the product 2) For the products of diameter or thickness # 40 mm the manufacturer may either apply: — the rules specified for products of diameter or thickness # 25 mm, or — take the test piece at a location nearer the centre than indicated in the figure 3) For products of round cross-section, the axis of the notch is approximately a diameter; for products with rectangular cross-section, the axis of the notch is perpendicular to the greatest rolled surface

products of thickness greater than or equal to mm use proportional test pieces of gauge length Lo = 5,65 √ So For normal testing, for reasons of economy, test pieces of a constant measuring length may be used provided the result obtained for elongation after breaking is converted by a recognized formula (see, for example, ISO 2566 Conversion of elongation values) For products of thickness greater than 30 mm a round test piece may be used if agreed between the parties Option 14 2) The axis of the notch shall be perpendicular to the surface of the product © BSI 12-1998 13 EN 10113-1:1993 Annex B
