Kiwa Watermark Certification and Testing for Fittings in Contact with Drinking Water

Kiwa Watermark certification under Kiwa evaluation guideline BRLK623 applies to plumbing fittings being used to make capillary soldering and/or thread connections, in tap water installations, household gas installations and in heating installations. The plumbing fittings are intended for use in combination with copper pipes according to the Kiwa guideline BRL-K760.

For the application in tap-water installations a maximum working pressure of 1000 kPa and a maximum water temperature of 90°C is applicable.

The evaluation guideline BRL K623 is a certification scheme for the Kiwa product certificate for plumbing fittings for capillary soldering and/or thread connections to copper tubes.

Kiwa Watermark certification under Kiwa evaluation guideline BRLK626 applies to fittings intended for jointing with any copper supply pipe under pressure according to NEN 2200 with outer diameters of 12, 15, 22, 28, 35, 42 and 54 mm.

The fittings are provided with a plunger with cutting edge that connects the supply pipe under the influence of gas pressure. The gas pressure is created after the ignition of an explosion cartridge.

The fittings are intended for use in drinking water installations with an operating pressure up to 1000 kPa and a temperature up to 90°C. Means for attaching the fittings to the pipes that are integral with the fittings are covered by this evaluation guideline.

Kiwa Watermark certification under Kiwa evaluation guideline BRLK639 applies to fittings with compression ends being used to connect copper pipes, according to the Kiwa evaluation guideline BRL-K760, in tap water and gas installations and in heating installations.

This mechanical connection is realized by compression, a cutting ring or deformation of the pipe end, with no use of soldering or screw thread on the copper tube. The fittings can also be applied underground in areas with no contaminated soil. For the application in tap-water installations a maximum working pressure of 1000 kPa and a maximum water temperature of 90°C is applicable.

Kiwa Watermark certification under Kiwa evaluation guideline BRLK640 applies to fittings to be tightened with matching compression tool, compression- and push fit fittings as part of an appliance or installation, to be applied in tap water installations with a maximum working pressure of 1000 kPa and a maximum water temperature of 90°C. These installations are either plastic or metallic.

Kiwa Watermark certification under Kiwa evaluation guideline BRLK773 applies to fittings with compression ends are being used to make tensile connections in drinking water installations with a maximum working pressure of 1000 kPa and a maximum water temperature of 90°C. The connections can be made with stainless steel tubes according Kiwa evaluation guideline BRL K762 and/ or copper tubes according to Kiwa evaluation guideline BRL-K760 in the quality ‘half hard’ and ‘hard’.

The compression fittings are not suitable for hard or soft soldering during installation, because of the risk of corrosion and the lack of a capillary gap. The compression fittings are suitable for making a connection with brass and red copper fittings without the risk of contact corrosion.

The evaluation guideline BRL K774 is a certification scheme for the Kiwa product certificate for compression fittings to tighten with matching clamping device.
