This BRL has been withdrawn on 1 March 2019 and has been placed in BRL-K767.

Kiwa Watermark certification under Kiwa evaluation guideline BRL K758 applies to the process of treating metal products to make these suitable for coating by a Kiwa-certified coating applicator (according to BRL-K746 or BRL-K790). The coatings used can be applied in dry form as a powder or in liquid form as a paint to protect against corrosion of metal fittings, pipes, valves, pumps, tanks, pressure vessels and the like. The process relates to the construction guideline for the application of both internal and external coating systems.

The evaluation guideline BRL K746 is a certification scheme for the Kiwa process certificate for coating suitability of metal products to be coated.

Kiwa Watermark certification under Kiwa evaluation guideline BRL K19004 applies to

• The application of protection systems on a mineral surface for drinking water applications (according to BRL-K19002; such as cement-bound mortars, cement-bound plastic-modified mortars or synthetic resin-bound mortars)
• The application of protection systems on a mineral surface for wastewater applications (according to BRL-K19006).

Evaluation guideline BRL K19004 sets requirements for the way in which and the conditions under which the mentioned protection systems must be applied to meet the set product requirements.

Kiwa Watermark certification under Kiwa evaluation guideline BRL K19006 applies to protection systems on mineral surfaces in installations for the purification, storage and / or transport of wastewater up to 35°C. The installations can be situated both in the ground and above the ground. The purpose of the protection system is to protect the mineral surfaces against the influence of wastewater.

The protection system can also serve to improve the surface structure or to repair or improve the durability of the concrete construction but is not assessed on the contribution to the structural properties of the substrate.

The evaluation guideline BRL K19006 is for the Kiwa product certificate for protection systems on mineral surfaces for wastewater applications.
