The requirements for zinc-aluminium coatings of type Zn95Al 5 are given in Table 2. For other zinc alloy coatings, the manufacturer and supplier shall agree on the required coating mass. 4.2.2 Appearance of coating The coating applied to the wire shall be reasonably smooth and as evenly distributed as industrial technology allows and not show discontinuities such as bare patches, dross contamination, etc. NOTE The Zn95Al5 zinc-aluminium alloy might show difference in colour and become darker with time. This does not affect the corrosion protection performance. 4.2.3 Dipping test When specified the dipping (immersion) test shall be carried out according to the procedure detailed in 5.3. However, it should be pointed out that there is no correlation between the number of dips and the mass of the coating and that the result is influenced as much by the conditions of manufacture of the coating as by the uniformity of the coating. Table 3 gives the minimum number of immersions for coatings of classes A and AB. The dipping test does not apply to class B, C and D. SIST EN 10244-2:2009
