28、flats for extruded square bar and thickness for extruded rectangular section, designated t. 4 Tensile testing For the selection of specimens and preparation of test pieces, see EN 603-1. Tensile testing shall be carried out in accordance with EN 10002-1. 5 Mechanical properties 5.1 Extruded forging
29、stock Extruded forging stock is normally supplied in the F or H112 temper condition. Testing to determine mechanical properties of extruded forging stock shall be undertaken only when requested by the purchaser and specified on the order (see EN 603-1). In instances where tensile testing is specifie
30、d on extruded forging stock in heat treatable alloys, the specimen selected for test shall be heat treated in accordance with the recommended practice for the temper condition of final use. The mechanical properties of aluminium alloys are specified in tables 1 to 6. Test results shall be rounded in
31、 accordance with the rules given in annex A. For section sizes greater than those quoted, the levels of mechanical properties shall be as agreed between purchaser and supplier. 5.2 Rolled forging stock Mechanical properties for rolled forging stock shall be subject to agreement between purchaser and
32、 supplier. 6 Electrical conductivity The electrical conductivity of extruded forging stock produced in alloy EN AW-7075 in the T732 temper condition shall be determined in accordance with EN 2004-1, as part of the inspection lot acceptance, by testing the surface of the previously selected tensile t
33、est specimen to the criteria shown in table 6.Page 4 EN 603-2 : 1996 BSI 1997 Table 1.

Electrical conductivity (g) MS/m Level of mechanical properties Lot
38、 acceptance status g$23,2 per specified requirements acceptable 22,0#g23,2 per specified requirements and R p0,2 does not exceed minimum specified in the standard by more than 85 MPa acceptable 22,0#g 23,2 per specified requirements but R p0,2 exceeds minimum specified in the standard by more than 8
39、5 MPa suspect (see note) g 22,0 any level unacceptable NOTE. When the lot acceptance status is found to be suspect, the specimen shall be reprocessed or subjected to a heat treatment for not less than 30 min at (465 5) C and quenched into cold water. Electrical conductivity shall then be measured wi
40、thin 15 min of quenching. If the difference between this measurement and the original measurement on the specimen is 3,5 MS/m or more, the inspection lot is acceptable. If the difference is less than 3,5 MS/m the inspection lot is unacceptable.Page 6 EN 603-2 : 1996 BSI 1997 Annex A (normative) Rule
41、s for rounding In recording test results, the number representing the result of a test to determine a given property shall be expressed to the same number of decimal places as the corresponding number in this European Standard. The following rounding rules shall be used for determination of complian
42、ce with this standard: a) When the figure immediately after the last figure to be retained is less than 5, the last figure to be retained remains unchanged; b) When the figure immediately after the last figure to be retained is greater than 5, or equal to 5 and followed by at least one figure other
43、than zero, the last figure to be retained is increased by one; c) When the figure immediately after the last figure to be retained is equal to 5 and followed by zeros only, the last figure to be retained remains unchanged if even and is increased by one if odd.
