16、DIN. 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of an identical text or by endorsement, at the latest by June 1998, and conflicting national standards shall be withdrawn at the latest by June 1998. Within its programme of work, Technical Committee
17、CEN/TC 133 requested CEN/TC 133/WG 2, Rolled flat products, to prepare the following standard: EN 1758, Copper and copper alloys Strip for lead frames. This is one of a series of European Standards for copper and copper alloy rolled flat products. Other products are, or will be, specified as follows
18、: EN 1172, Copper and copper alloys Sheet and strip for building purposes. EN 1652, Copper and copper alloys Plate, sheet, strip and circles for general purposes. EN 1653, Copper and copper alloys Plate, sheet and circles for boilers, pressure vessels and hot water storage units. EN 1654, Copper and
19、 copper alloys Strip for springs and connectors. Copper and copper alloys Copper plate, sheet and strip for electrical purposes. (WI: 00133022) This standard gives information, which might be useful to the user, on physical properties of the product contained in annex A. According to the CEN/CENELEC
20、 Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switze
