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.

Figure A.3 — Flat products 1)

In case of doubt or dispute, for products of thickness greater than or equal to 3 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.
