Within the text, the SI units are shown in brackets, except 4a80 when AM is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product speci? Thickness tolerances given in mm unless otherwise indicated.

Bright Annealed Finish—See Note 4. In the case of heavier plates of types other than L, LN, Cb, Cb, Cb, L, LN, Ti, L,S, and S, the applicability of this test shall be a matter for negotiation between the seller and the purchaser. Such requirements may include, but are not limited to, the following: In the case of polished? For narrow strip, the following widths can be tested: If the hardness difference between the two ends of the coil exceeds 5 HRB, or equivalent, or if the material is temper rolled, tensile properties must be determined on both coil ends.
However, it is not necessary to actually run the test unless it is speci?

For plates up to 10 in. B For circles, the over thickness tolerances in this table apply to the diameter of the circle corresponding to the width ranges shown.
The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; a4800 example, by waiving a test requirement or by making a test requirement less stringent. This is a general purpose? NOTE 1—A typical ordering description is as follows: Refer to Section Edges for Cold-Rolled Strip The values stated in each system are not exact equivalents; therefore, each system must be used independently asfm the other.
