Tôles en acier laminées a chaud a limite d’élasticité et aptitude au form age accrues.
8.2 Impact test
While not usually specified, if so agreed at the time of ordering, impact tests may be specified for material over 6 mm in thickness. The test piece shall be in the longitudinal direction and the test shall be carried out in accordance with ISO 148-1.
9 Retests
9.1 Machining and flaws
If any test piece shows defective machining or develops flaws, it shall be discarded and another piece substituted.
9.2 Elongation
If the percentage elongation of any test piece is less than that specified in TaIe4, and if any part of the fracture is outside the middle half of the gauge length as scribed before the test, the test shall be discarded and a retest shall be carried out.
9.3 Additional tests
If a test does not give the specified results, two more tests shall be carried out at random on the same lot. Both retests shall conform to the requirements of this International Standard; otherwise, the lot shall be rejected.
10 Resubmission
10.1 The manufacturer may resubmit for acceptance the products that have been rejected during earlier inspection because of unsatisfactory properties, after he has subjected them to a suitable treatment, (for example: selection, heat treatment), which, on request, will be indicated to the purchaser. In this case, the tests should be carried out as if they applied to a new batch.
10.2 The manufacturer has the right to present the rejected products to a new examination for compliance with the requirements for another grade.
11 Workmanship
11.1 The surface condition shall be that normally obtained in a hot-rolled or hot-rolled descaled product.
11.2 The steel sheet in cut lengths shall be free from quantities of laminations. surface flaws and other imperfections that are detrimental to subsequent appropriate processing.
11.3 Processing for shipment in coils does not afford the manufacturer the opportunity to observe readily or to remove imperfect portions, as can be carried out on the cut length product.
12 Inspection and acceptance
12.1 Although not usually required [or products covered by this International Standard, when the purchaser specifies that inspection and tests for acceptance be observed prior to shipment from the manufacturer’s works, the manufacturer shall afford the purchaser’s inspector all reasonable facilities to determine that the steel is being furnished in accordance with this International Standard.
12.2 Steel that is reported to be defective after arrival at the user’s works shall be set aside, properly and correctly identified and adequately protected. The manufacturer shall be notified In order that he may properly investigate.
13 Coil size
When hot-rolled steel sheet is ordered in coils, a minimum inside diameter (ID) or range of acceptable inside diameters shall be specified. In addition, the maximum outside diameter (OD) and the maximum acceptable coil mass shall be specified.
14 Marking
Unless otherwise stated, the following minimum requirements for identifying the steel shall be legibly stencilled on the top of each lift or shown on a tag attached to each coil or shipping unit:
a) the manufacturer’s name or identifying brand;
b) the number of this International Standard;
c) the grade designation;
d) the order number;
e) the product dimensions;
f) the lot number;
g) the mass.ISO 5951-2013 pdf free download.
