The accredited testing laboratory of the Klokner Institute provides a series of material tests on concrete, mortar, masonry, steel, ceramics, wood and stone. The laboratory also has accredited methods for mechanical tests of electrical insulators, waterproofing, dripping of surface layers to their underlayment, and tests of moisture vapour transmission. Other methods are mainly related to static and dynamic loading tests, which can be performed on small structural elements directly at the Institute or in-situ, especially bridge loading tests. A detailed summary of accredited testing methods is contained in the Annexe to the Accreditation Certificate issued by CAI (the valid annexe can be downloaded from www.cia.cz).
- Tests on concrete and mortar mixtures (compressive strength, tensile strength, bending strength, elastic modulus, frost resistance, changes in volume),
- Quality investigations of cable elements and prestressing cables,
- Tests on welded reinforcement of concrete,
- Tests on anchor systems,
- Static loading tests on bridges,
- Dynamic loading tests on building structures, and assessment of effects of machine vibration on structures and on human beings,
- Tests on electrical insulators in tension, compression, bending and torsion,
- Quality assessment of building materials on the basis of laboratory experiments (concrete, mortar, stone, wood, masonryelements and masonry structures),
- Assessments of resistance of materials to penetrationby water vapour.
