The internal tinning of copper tubes is intended to reduce the migration of copper into the drinking water, for those applications where this could be a point of consideration. The tubes can be supplied in the annealed, half hard and hard material temper conditions. Kiwa Watermark certification under Kiwa evaluation guideline BRL K19005 applies to internally tinned copper tubes are intended to be used in the transport of hot (≤90☌) or cold water intended for human consumption. The evaluation guideline BRL K10018 is a certification scheme for the Kiwa product certificate for piping systems with thin copper tubes with an external solid fixed plastic covering. Under the certification products we understand the copper tubes with an external fixed plastic covering with the fitting, the combination, copper tube and fittings are listed on the product certificate. In the latter case the covering shall meet the additional materials requirements as specified. In addition, the covering can be used for providing a thermal insulation for the pipe. The external covering is primarily intended for the chemical and mechanical protection of the pipe surface during transportation, installation and service.
