19、ecifies the tolerances on dimensions for single and double-rolled aluminium and aluminium alloy foil supplied in accordance with EN 546-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited ap
20、plies. For undated references, the latest edition of the referenced document (including any amendments) applies. Not Applicable 3 Tolerances on dimensions for single-rolled foil 3.1 Gauge 3.1.1 Single gauge measurement The tolerance on gauge for a single measurement for single-rolled foil shall be 6
21、 %. Gauge can be measured with any of the usual precision instruments capable of assessing foil thickness but, in the event of a dispute, the weighing method shall be used as a referee procedure. Description of the weighing method: for the test sample, cut an area A of approximately 1 dm2either squa
22、re or circular. Degrease the sample if necessary in a suitable solvent and 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 with an accuracy of equal to or better than 0,1 mm. Gauge
23、shall be calculated by use of the formula: DAME=10where: E is the gauge in micrometres; 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.
