BS 6920 is a requirement for manufacturers and suppliers of non-metallic materials/products that are used in contact with drinking water.

The Ü-mark indicates the usability of a construction product in Germany according to national requirements which are not covered by CE marking.

The FI drinking water approval is a quality mark and demonstrates that the product complies with the applicable regulatory requirements regarding to the plastic pipe material and possible odour or taste passed on from the pipe to water.

IRENE Pro is more than a gas network calculation program. It is an analysis tool for designing gas networks, performing network calculations and determining the level of risk or delivery reliability.

The resistance against permeation of gases and water through pipe walls and other separation components such as films, is for many practical applications a very important property. In this area, Kiwa Technology has gained vast knowledge and experience.

Safeguard approved construction products continue measuring up to the requirements with inspection by an independent inspection body. Kiwa Sverige AB is accepted in Denmark, Finland, Norway and Sweden for conducting inspection for; GDV, SINTEF, STF and VA.

In Germany, plastic products of all kinds as well as rubber products that come into contact with drinking water must meet the hygienic and toxicological requirements of the guidelines of the Federal Environment Agency test (UBA). This is described in the elastomer guideline as well as in the KTW guideline.

The quality of (city) heating networks depends to a significant extent on the quality of the connections in the pipelines. Leaks that allow water ingress, which often occur in sleeve connections, can lead to degradation of the insulation with all the resulting effects on thermal insulation performance

Kiwa Technology carries out feasibility studies to support gas traders, fleet owners and governments; to facilitate investment, safety, and provide an overview on the possibilities of alternative fuels CNG, LNG, H2 and CH2. To serve this objective, the study covers various aspects of the business concept development.

Kiwa Technology investigates the cause of all types of accidents involving gas. These investigations are required in order to continue to use gas safely and also in order to assign responsibility for damages to the right parties.

Problems in pipelines are often caused by the joints. Kiwa Technology has built up vast experience. For example, we have used our expertise in the area of plastic welding (of PE, PEX, PA, PP etc.) and other jointing techniques for years to support our consultancy regarding research and development projects.

Kiwa Energy is a leading testing and certification body for hydrogen and other gas-fuelled appliances. We also specialise in fuel cell power, mCHP, portable device and fuel cell systems – whether fuelled by pure hydrogen or using other feedstocks.

When the composition of the gas is crucial. Particularly when the calorific value or Wobbe index needs to be identified. In addition, it is important that the gas is free of detrimental trace components. The possible presence of certain trace components depends strongly on the origin of the gas.

If you have, or are developing, a new product in the area of heat energy distribution, such as delivery sets or heat pump systems, you obviously want to be sure that this product is as good as possible and that it complies with all the relevant standards.

Hydrogen and gas safety expertise

The KIWA-UNI mark certifies the conformity of plastic and metal components in contact with water and gas to national and international standards.

Natural gas, hydrogen gas and many other gases are naturally odorless. This can cause dangerous situations, for example if a leak or other incident occurs. Gases that are distributed via the Dutch gas network must therefore be scented with a so-called odorant.

The energy infrastructure is becoming increasingly complex. In the past, all users were purchasers of electricity and gas or heat. Now a much greater variety of technologies is available such as heat pumps, home heat and power plants, solar-powered boilers and wind turbines.

Ladders, safety glass, plastic pipes and toilet seat, toilet washbasin. The INSTA-CERT product certification and the Nordic Poly Mark demonstrate that the products meet the Nordic quality level.

According to the law of Finland, the manufacturer should demonstrate that the construction product meets the set requirements. Type Approval is the simplest way to demonstrate conformity.
