Corrosion Resistance Testing

Corrosion resistance tests are performed in our laboratory in Jablonec nad Nisou on modern LIEBISH and QLAB chambers. The QLAB cyclic chamber can alternate the environment (NSS, condensed water, air, shower) and can be set to different temperatures and humidity levels according to customer requirements. The LIEBISH chamber is designed for NSS testing.

QLAB chamber

Volume of the test space: 1 100 ^dm3. The temperature range for these tests is 20°C to 70°C, humidity up to 100%. Chamber dimensions (l x w x h) = (1400 x 900 x 400) mm.

Tests may be carried out according to the procedures listed below:

ASTM B117, CCT-1 (CCT-A)
Ford CETP:00.00-L-467, ISO 16701, GB/T 20853
Volkswagen PV 1210
Volvo VCS 1027,14; 1027,149; 423-0014
EN 14592:2022, Nordtest Method NT MAT 003
Other uses depend on test requirements

LIEBISH chamber

Corrosion resistance in the fog of neutral sodium chloride solution by the NSS method (neutral salt spray) according to EN ISO 9227 and evaluation according to customer requirements. Chamber dimensions (l x w x h) = (1500 x 750 x 450) mm.

What is being assessed:

Appearance and changes in surface finish on the products during and after the test
the resistance of the coatings after the condensation chamber test
adhesion after cutting tool test
degree of delamination, blistering, flaking, rusting, etc.

What is the output:

Accredited testing laboratory report with photo documentation and evaluation.

Why test:

Corrosion adversely affects the performance of products or equipment. Testing in corrosion chambers allows you to compare a test sample and a reference sample, or test samples, with each other and detect potential problems in manufacturing or coating.

Corrosion testing has a wide range of applications in the engineering, automotive, aerospace, construction etc. industries as it can assist in the selection of materials, components and surface treatments to ensure optimum service life.

UV chamber

We perform tests in our modern QLAB UV chamber.

Our chamber uses UVA 340+ lamps and it is possible to perform tests of paints, plastics and textiles.

Tests are performed according to the standards:

EN ISO 16474-3
EN ISO 4892-3
EN ISO 12944-6: It is also possible to perform cyclic aging test according to Annex B of EN ISO 12944-6. This test is required for high durability of C4 and C5 grades.

What is output:

Protocol from the accredited testing laboratory with photo documentation and evaluation.

Why test:

UV radiation simulates and accelerates the aging of materials. This test method can show changes in the properties of materials that occur when exposed to UV radiation. Changes that occur can be: discoloration, loss of light, cracking, blistering, brittleness, loss of strength, and oxidation. These changes affect appearance, performance, and durability. UV radiation can be used to find design and material defects. It can also predict the durability of products.
