Independent arbitration for polymers

Plastics are often used out- or indoors exposed to daylight or to daylight behind glass for long periods. The effects of daylight, heat, moisture and other climatic stresses may have influence on the aesthetic and mechanical properties of plastics and for that reason the resistance to these effects is investigated.

Polymers are widely used in construction, building and infrastructure. Construction and utility parts in buildings are often partly or completely polymeric or elastomeric products. This can be as wall panels, roofing materials, piping systems, seals, coatings and a large number of other products.

Reliablity engineering of plastic and rubber products. The realisation of reliable polymer and rubber products starts in the design or engineering stage. There the fundamental choices are made that have a major influence on the functioning of the product in the end.

ISO 50001 Energy Management system certification with Kiwa: conserve resources, save money and mitigate climate change.

Within the Kiwa organisation there are a large number of accredited laboratories. This means that the scope of possible tests within the entire Kiwa Group is so wide that is impossible to mention them all here. Although not limited to polymer test...

Wind-uplift test

The objective of this guideline is to guarantee the drinking water quality by specific relevant additional testing and criteria on the barrier properties of the piping system for an operation period of 50 years in polluted soil.

Effective and long term performance of rubber seals is essential to prevent leakage of pipelines and subsequent spillage of water and high costs for repair and damage. Increasingly, authorities, pipe system suppliers and other parties in the chain of custody are demanding proof of quality of rubber seals.

Safe electrical installations are essential to a property and a major part of any construction project. Kiwa Inspecta helps you to ensure that your property and operation has safer electrical installations and your employees are properly trained to minimize danger.

Do you have questions about the composition or nature of a polymer material, component, a contamination or a chemical attack? Good to know that Kiwa has a large number of laboratories that are well equipped with a broad variety of different chemic...

Raba Kistner is known throughout the industry as a leader for providing inspection and testing services of construction materials.

Kiwa supports you with all services concerning testing, inspection and certification of concrete according to EN 206 and concrete products. For in-situ concrete, we inspect and certify e.g., according to national standards. Furthermore, we have all the testing facilities for in-situ testing and laboratory testing.

Testing, inspection and certification of floor coverings. Waterproofing membranes including liquid applied waterproofing and kits (for waterproofing against water and/or steam).

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

The Plastica Seconda Vita (PSV) mark is the first European Environmental Product Certification system for products and materials obtained from the valorisation of plastic waste.

With ReTHiNK you can independently create life cycle assessments and EPDs for your products. A life cycle assessment (LCA) provides information on the environmental impacts (such as global warming potential, eutrophication potential or resource consumption) of your product over its entire life cycle.

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.

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

Our expertise includes field exploration services, laboratory testing, and engineering evaluation and reporting. We have worked on large, significant projects, and have tailored cost-effective services for each.
