Theory & Practice in Material Light-Exposure Testing

Basic information about the seminar

Together with our experienced lecturer and certified corrosion engineer Ing. Ondřej Janča, we are preparing a one-day seminar aimed at introducing participants to the principles of simulating solar radiation and the climatic effects of weathering on materials and their degradation. The seminar combines expert explanation with practical demonstrations of measurement and evaluation of results.

The seminar is suitable for technicians, laboratory staff, technologists, development staff and quality managers who want to understand the effect of climatic conditions on materials and learn to interpret the results of light-exposure tests correctly.

So that we can give every participant our full attention, the seminar capacity is limited to 12 people. Earlier registrations take priority, so do not hesitate to register.

Register

Radiation and materials

Classification of the types of radiation (UV, VIS, IR) and their interaction with the material.

Types of environment and the influence of climate

Simulation of dry (Kalahari), humid (Florida), temperate and offshore conditions, radiation intensity and combinations of effects (UV, heat, humidity, salt).

Types of tests

UV and full-spectrum tests, climatic tests and combined cycles, with an explanation of their significance.

Practical measurement

Demonstrations and practical measurement of colorimetry, gloss and surface roughness, with interpretation of results and changes in appearance.

Seminar content

Introduction to light-exposure tests
