BS ISO 5954:2013 pdf free.Cold-reduced carbon steel sheet according to hardness requirements
Although bend tests are not required, CRH-50 is expected to be capable of being bent flat on itself through 180°,both parallel and perpendicular to the rolling direction. CRH-60 is expected to be capable of being bent through 90°, with the axis of bend parallel to the rolling direction on a 1 thickness radius, or flat on itself perpendicular to the rolling direction with a 1 thickness radius. CRH-70 is expected to be capable of being bent 90° with a 1 thickness radius perpendicular to the rolling direction. By agreement between the supplier and purchaser, a bend test may be carried out with these or other values of bend radi.
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 may be rejected.
The manufacturer may resubmit for acceptance the products that have been rejected during earlier inspection due to unsatisfactory properties, after the manufacturer has subjected them to a suitable treatment (for example, selection or heat treatment).
In this case, the tests shall be carried out as if they applied to a new lot.The manufacturer has the right to present the rejected products to a new examination for compliance with the requirements for another designation.
The surface condition should be that normally obtained in a cold-reduced product. The steel sheet in cut lengths shall be free from any laminations, surface flaws and other imperfections that are detrimental to the final product or to subsequent processing.
NOTE Processing for shipment in coils does not afford the manufacturer the opportunity of readily observing or removing defective portions, as would be the case on the cut-length product.
While not usually required for products covered by BS ISO 5954, when the purchaser specifies that inspection and tests for acceptance shall 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 BS ISO 5954.
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 supplier shall be notified in order that the supplier can properly investigate.BS ISO 5954 pdf download.
