Global Ethics Day 2026: choosing what is right over what is easy

Every day, our customers and the organizations in their supply chains make decisions based on a Kiwa certificate, test report, inspection finding or consultant’s analysis. They decide whether a product is of the right quality and can go to market, whether a building or structure can be safely occupied or used and whether important data is secure across their value chain.

Strip bend test: Quality assessment of an electrofusion joint

A joint in a plastic piping system made of, for example, polyethylene (PE) must function reliably for many years, often under high pressure and in critical applications such as drinking water and gas networks. Therefore, it is essential to accurately assess the quality of these joints.

FTIR: Identification of (undersired) liquids in gas distribution networks - natural gas condensate

Sometimes liquids occur unintentionally in the gas distribution network. These include, for example, condensed gases from the gas network, often referred to as ‘natural gas condensate’. Liquids in the gas network can be harmful to both human health and the environment. Therefore, correct procedures for removing these liquids are essential. The procedures depend on the type of liquid, which cannot always be determined by visual inspection. Fortunately, there is a solution: infrared spectroscopy (FTIR). This measurement method makes it possible to identify the type of liquid.
