20、pplication The present standard specifies the particular requirements for aluminium and aluminium alloy wire intended for rivet manufacture. This standard shall be used in conjunction with EN2070-1. 2 References ISO/R 2101:1971, Aluminium and aluminium alloys Shear test for rivet wire and rivets. EN

EN 2070-1, Aerospace series Aluminium and aluminium alloy wrought products Technical specification Part 1: General requirements. 3 Batch size The maximum weight of the batch shall be500kg.
22、4 Dimensions Dimensions and tolerances shall conform to the relevant semi-finished product standard. The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements. 5 External defects Visual surface inspection shall be carried o
23、ut at a frequency sufficient to permit the manufacturer to certify compliance with the requirements of this clause. The wire shall be clean and smooth and free from defects such as drawing scores, die pick-up, indentations, cracks or corrosion considered harmful to its use. 6 Mechanical testing Wire
24、 shall be submitted to either the tensile test in accordance with EN2002-1 or the shear test, in accordance with ISO/R2101 at the option of the manufacturer in the condition of supply and/or use as required by the material standard. The frequency of testing is given inTable 1. The values obtained sh
25、all meet the requirements of the material standard. Regardless of the type of test carried out, the wire shall be capable of meeting the tensile test and shear test values required by the material standard. Re-testing procedure for shear testing shall be as EN2070-1 “Tensile re-tests”. 7 Suitability
26、 for cold heading The quality of the wire shall be such that cold headed rivet shapes can be produced without developing cracks, or general or localized excessive grain growth after heat treatment. Evaluation of forming capability shall be accomplished, for example, by some type of torsion test or a
27、 cold heading test or such other tests as may be agreed between the manufacturer and purchaser. The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements. 8 Special tests Special tests and inspections may be required by the
28、 purchaser. In such cases, after agreement between purchaser and manufacturer, nature of the tests, methods, number and acceptance standards shall be specified on the order or in the inspection schedule. 9 Marking A durable label attached to each coil or bundle shall bear the information required by
29、 EN2070-1 (Clause10.1) in addition to the following: wire diameter, weight of coil or bundle in kg. If special tests in accordance with clause8 are required the marking shall be defined and shall reflect these extra requirements. The frequency of examination adopted by the manufacturer shall be suff
