22、g wire to which an aluminium coating has been applied primarily to protect it against corrosion and/or to improve its electrical conductivity. The coating is generally applied by passing the wires individually through a bath of molten aluminium, by extrusion or by cladding 3.2 mass of coating mass o
23、f aluminium per unit area is expressed in grams per square meter of stripped wire surface. In the case of thick coatings, the quantity of aluminium on the wire may also be expressed by the radial thickness 4 Requirements relating to coating 4.1 Material The ingot of unrefined aluminium used for the
24、coating shall consist of aluminium with less than the following impurities: Copper (Cu) 0,lO ?lo max. in mass % Iron (Fe) 0,50 % max. in mass % 4.2 Coating mass The minimum mass of aluminium per unit surface area shall comply with the requirements of Table 1. The product standard relating to wire pr
25、oducts with an aluminium coating may specify different requirements for minimum mass.

26、with good commercial practice. The coating on the wire shall be continuous, reasonably smooth and as evenly distributed as practicable. 4.4 Adherence of the coating The aluminium wire shall be tested in accordance with EN 10244-1. The mandrel for the wrapping test shall have a diameter equal to thre
27、e times the nominal diameter of the wire tested. 4.5 Special finishes If the customer requires a special finish it shall be specified at the time of enquiry and order. Similarly if drawing after coating with aluminium is requested it shall be specified at the time of enquiry and order. 5 Tests condi

29、d as indicated in EN 10244-1. The stripping solution, sampling, and other procedures, shall be in accordance with ASTM A428. The calculation of the coatings mass is based on the difference in weight in grammes of a test specimen before and after stripping. if Am = difference in weight by stripping i
