Environmental testing and corrosion resistance testing are type tests that nearly every new product and ma-terial has to pass, before placing it on the market. The tests are also used for quality control, qualification of corrosion-resistant materials, material or production technology substitution, and for verification that the ma-terial, component or end-product can withstand different environmental conditions.
Test scope:• environmental testing of products and materials (cold, dry heat,
damp heat, change of temperature, water condensation, solar/UV radiation resistance)
• environmental testing of products and materials in extremely corrosive atmosphere (H2S, HCl, SO2 and NOx)
• corrosion tests in artificial atmospheres - salt spray tests, cyclic salt spray test, intergranullar and pitting tests
• evaluation of coating degradation: assessment of the degree of blistering, rusting, cracking, flaking and delamination
• coating thickness testing
• coating adhesion testing (cross-cut test, pull-off test)
• coating hardness testing (indentation test)

Mechanical and technological testing
Metallographic and fractographic examination, RoHS
Most commonly tested samples:• metal samples • plastic samples• rubber samples• wire samples• insulators
• paper samples• pressboard• laminated pressboard• laminated wood• composite materials
• conductor samples• cables
Aim of metallographic examination is to study phys-ical structure and composition of metals, while frac-tographic examination aims to determine the cause of failure by studying the characteristics of fracture surfaces.The examination can be done on samples submitted to the Laboratory or on replica taken from construc-tion parts on site. Chemical composition of the ma-terial is very important information for material ex-amination and the analysis can be done by Optical Emission Spectroscopy (OES) or Energy Dispersive X-ray Fluorescence Spectroscopy (ED-XRF). The ED-XRF is also used as a quick screening method for detection of RoHS.Test scope:• metallography and fractography• elemental analysis of metal• ROHS elemental analysisTest methods:• optical microscopy• optical emission spectrometer (OES)• XRF (X-ray fluorescence analysis)The most commonly tested samples:• Fe, Cu and Al alloys
