GB/T 3615—1999
Foreword
This standard is a revision of (GJ3/Ⅱ3615-1983 "Aluminum foil for electrolytic capacitors". The alloy grades and states are expressed in accordance with the new national standard GB/T16474-1996 "Deformed aluminum and aluminum alloy grades" and GB/T16475-1996 "Deformed aluminum and aluminum alloy state substitutes". Compared with the previous version, this version has major changes in the following contents: the addition of a foreword, reference standards, scope, and contract content. In the product variety classification:
Added 1070A, 1A95, 3003 alloy grades. The original 1.T75 grade was cancelled. In the technical requirements:
Thickness and width allowable deviations are tightened.
Indicates Gold-containing purposes.
--Added typical outer diameter content
---Added inspections for pinholes and adhesion rates. The thickness range is adjusted most appropriately.
---The allowable deviation of the core length is relaxed.
---The repeated tests of mechanical properties and mechanical properties are cancelled. This standard was proposed by the State Bureau of Nonferrous Metals Industry. This standard is under the jurisdiction of the China Nonferrous Metals Industry Standard Metrology and Quality Research Institute.
