BS EN 16087 is a European standard on the influence of metallic materials on water intended for human consumption that discusses the dynamic rig test for assessment of surface coatings with nickel layers to ensure water is safe for human consumption.
BS EN 16087 specifies a procedure to determine the release of nickel from nickel layers or a coating containing nickel on the inner surfaces of products that are intended to encounter drinking water.
The test method given in BS EN 16087 is designed to provide information on nickel release over time from surfaces of products having a coating containing nickel which are in contact with drinking water. This nickel coating may be added intentionally, or part formed unintentionally i.e., it might appear due to electrostatic conditions in the process.
BS EN 16058 on the rig test for assessment of surface coatings with nickel layers is useful for:
Contact between metallic materials and drinking water can cause metal release into the water. Metal released from product surfaces in contact with drinking water is caused by corrosion of any metal films or layers present on the products and the bulk material.
Metal release from the bulk material depends on the composition of the material. The bulk material can release metals for an extended period. This long-term behaviour depends on the formation of protective layers of corrosion products on the surface of the material.
BS EN 16058 provides you with guidance on the test rig, operation, test water, test water sampling, sampling to determine metal release, analysis, expression of results, test rig components and assembly and much more.
The test method provided by BS EN 16058 helps in the assessment of surface coatings with nickel layers in water intended for human consumption and the influence of metallic materials on water intended for human consumption, improving the quality of drinking water and ensuring a reduction in the risk of health issues due to consumption of nickel content.
