VIBRATION AND ENVIRONMENTAL TESTS
- mechanical resistance tests
- environmental and corrosion tests
MECHANICAL RESISTANCE TESTS
VZLU provides a wide range of development,
qualification and serial tests for products from
variety of sectors. These are primarily tests focusing
on mechanical and climatic resistance of products.
The most requested tests include mechanical
vibration tests, which are carried out on modern
electrodynamic vibration and shock devices that
enable the tests to be combined (vibration, shock,
temperature, humidity).

ENVIRONMENTAL AND CORROSION
TESTS OF PRODUCTS AND SURFACE
TREATMENT
Complex environmental and corrosion tests
of products and surface treatment in specialpurpose chambers for testing systems and devices
destinated for operating at extreme conditions,
such as humidity, heat, cold, etc. + thermal shocks
tests, salt spraying and sulphur dioxide tests, cyclic
combined tests (e.g. SWAAT), ozone, solar radiation,
sand and dust tests, degree of protection provided
by enclosure (IP Code) and other.
VZLU testing laboratories also solve complex
corrosion problems, that negatively affect operating
life of products.
