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.

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...

Certification of vulcanised rubber products for drinking water applications (BRL K17504)

Welding is a special manufacturing process which is used in sectors to reveal structures which cannot be manufactured as one piece. The EN ISO 3834 series standards are also standards that define all Quality requirements for the operation of this particular process.

Self-regulatory Safety Check. Objects of Declaration of Conformity are classified of 3 groups with hazardous machines, protective devices and personal protective equipment.

WPQR is the process of examining the welding procedure during the compliance process according to the relevant standards (manufacturer's production, supervising the welding test, carrying out the testing procedures and evaluating them).

Kiwa is your partner for independent testing, certification and quality related services regarding polymeric roofing products. The first thoughts arising when talking about roofing products are not about polymers, but about clay or concrete tiles for pitched roofs or bitumen sheets in case of flat roofs.

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.

The use of reinforced plastic products has been growing steadily, especially in automotive and aerospace applications as well as in piping systems. This is largely due to the materials’ recyclability and ability to be processed rapidly and it's strength. Kiwa polymers experts serves many industries in this field.

Kiwa carries out tests according to EN 1504-4. Identification and proof of performance of building adhesives; CE marking and certification.

Kiwa carries out all tests of the DIN EN 14188 series of standards, e.g. the tests according to DIN EN 13880, parts 1-13. This is a test of hot-applied and cold-applied joint sealants as well as joint profiles for road construction, airports and other traffic surfaces.

We are specialized in testing of anchors in concrete and masonry. Your partner to get trusted results on fasteners.
