14、riat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2007, and conflicting national standards shall be withdrawn at the latest by June 2007. This document supersede

15、s EN 683-3:1996. Within its program of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 6 “Foil and finstock“ to revise EN 683-3:1996. The following modifications have been made: subclause 3.1.1: the text has been amended; subclause 3.1.2: title is changed alloys EN AW-6060 and EN AW-695

16、1 have been deleted in Table 2; subclause 3.3: lateral bow is applicable to thickness greater than 130 m. Test procedures have been amended and acceptance criteria have been edited. EN 683 comprises the following parts under the general title “Aluminium and aluminium alloys Finstock“: Part 1: Techni

17、cal conditions for inspection and delivery Part 2: Mechanical properties Part 3: Tolerances on dimensions and form Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such p

18、atent rights. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions, then this product shall be removed from the corresponding standard. According to the CEN/CENELEC Internal

19、 Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlan

21、luminium and wrought aluminium alloy finstock supplied in accordance with EN 683-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of th

22、e referenced document (including any amendments) applies. Not applicable 3 Tolerances on dimensions and form 3.1 Gauge 3.1.1 Single gauge measurement The tolerance on gauge for a single measurement for finstock shall be 6 %. Gauge can be measured with any of the usual precision instruments capable o

23、f assessing finstock thickness but, in the event of a dispute, the weighing method shall be used as a referee procedure. Description of the weighing method: From the test sample, cut an area (A) of approximately 1 dm2either square or circular. Degrease the sample if necessary in a suitable solvent a

24、nd weigh on a laboratory balance with an accuracy of equal to or better than 1 mg. The dimensions of the sample (sides of square or diameter of circle) shall be measured to an accuracy of equal or better than 0,1 mm. Gauge shall be calculated by use of the formula: DAME=10where: E is the gauge in mi

25、crometres; M is the mass in milligrams; D is the density as defined in Table 2, in grams per cubic centimetre; A is the area in square decimetres. 3.1.2 Average gauge evaluation The tolerance on average gauge is specified in Table 1.

The mean gauge shall be calculated by the formula: DWLPEm=610where: Emis the average gauge in micrometres; P is the net mass in kilograms; L is the length in metres; W is the width in millimetres; D is the density as defined in Table 2, in grams per cubic centimetres.

31、 a thickness greater than 130 m; on narrow width finstock (width up to 100 mm), this measurement shall be carried out only if required by the purchaser. One of the following test procedures shall be used. a) Take a sample from the first set of slit reels produced from the parent coil. Cut one 2 000

32、mm length from that sample. Measure the lateral bow called a against a straight edge as shown on Figure 1 on length of 2 000 mm. Dimensions in millimetres Figure 1 Measurement of lateral bow: method a) b) Take a sample from the first set of slit reels produced from the parent coil. Cut two 1 000 mm

33、lengths from that sample. Place the two lengths back to back on a flat surface. Measure the maximum distance called b between the two lengths as shown in Figure 2.
