The AAAC-BS 3242 standard is a standard formulated by the British Standards Institution (BSI) that regulates various dimensions, physical properties, mechanical properties and electrical properties of AAAC.
This standard refers to the International Electrotechnical Commission (International Electrotechnical Commission, referred to as IEC) 61089 standard, and is consistent with the European standard EN 50182.
The standard divides AAAC into three grades: A1, A2 and A3, among which A1 is the highest grade, contains the most magnesium, has the highest strength and the lowest elongation; A3 is the lowest grade, contains the least magnesium, Has the lowest strength and highest elongation; A2 is an intermediate grade that strikes a balance between the two. The standard also stipulates the diameter, quality, DC resistance, AC impedance, calculated breaking load, modulus and other parameters of AAAC wires with different cross-sectional areas (from 10mm² to 800mm²) in different grades.
