(2) The wire is to be drawn in continuous pieces of the weights and diameters given in the Table. Every piece may be gauged for diameter in one or more places. (3) The wire is to be well galvan...ised with zinc spelter, and this will be tested by an officer (hereinafter called the Inspecting Officer) appointed by the Postmaster-General for the purpose of inspecting and testing the wire taking samples from any piece or pieces and plunging them into a saturated solution of sulphate of copper at 60 Fahrenheit, and allowing them to remain in the solution for one minute, when they are to be withdrawn and wiped clean. The galvanising shall admit of this process being four times performed with each sample without there being any sign of a reddish deposit of metallic copper on the wire, which would be the case if the coating of zinc were too thin.
