7、 requirements-for manufacture, inspection and testing of aluminium alloy forging stock and forgings. Particular requirements applicable to forging stock, pre-production forgings and production forgings are defined in EN2082-2 and EN2082-3 respectively. The three Standards EN2082-1, EN2082-2 and EN20
8、82-3 define the inspection level and the sampling frequencies tc.be applied unless otherwise specified on the drawing, order or inspection schedule. 2 Field of appiication Unless otherwise specified on the drawing, order or inspection schedule this standard shall be applied when referenced in the re
9、levant EN material standarcis. It is applicable to : - Forging stock (EN2082-2), - Hand forgings including forged blocks and rings, die forgings and rolled rings (EN2082-3), hereafter described as “forgings“. By agreement between the purchaser and the manufacturer, it may also be applied to other ma
10、terials or delivery conditions not covered by EN standards. The agreements shall be formalized by reference to this standard on the drawing, order or inspection schedule. 3 References .EN2078, Definitions of manufacturing schedule inspection schedule and inspection report - General-definitions - Aer
