Agenda Day 1


9:00 – 9:15


9:15 – 10:30

Part 1: Factors of weather

              Learn about the influences of weather, i.e. sunlight, temperature and humidity, are described.

10:30 – 10:50

Coffee break

10:50 – 12:00

Part 2: Outdoor weathering

              The fundamentals of natural weathering are described. This includes static exposures in different                         reference climate zones, as well as various accelerated methods for natural weathering.

12:00 – 13:00

Lunch break

13:00 – 14:00

Part 3: Laboratory weathering

              In this section different kind of weathering laboratory instruments are described. What is the light                       source and its spectral power distribution? Which is the right instrument for which application?

14:00 – 14:45

Part 4: Weathering standards

              Purpose of standards for weathering testing are describes. Examples are given on the most common                   test methods for automotive, textiles, coatings, pharmaceuticals and other applications (ISO                                 4892/105 B02+B06/16474, ASTM G155/D7869, SAE, ICH …)

14:45 – 15:10

Coffee break

15:10 – 15:40

Part 5: Reference materials for weathering tests

              Standard reference or control materials are recommended for the validation of accelerated test                           methods and for control of the instrument performance.

15:40 – 16:10

Part 6: Acceleration/Intensifying tests

              Principles are shown on how to accelerate weathering tests and what has to be considered to avoid                     unrealistic results.

16:10 – 16:45


Agenda Day 2


9:00 – 9:15

Summary of day 1

9:15 – 10:30

Part 1: Effects of weather on polymers

              The effects of primary and secondary weather factors on materials are described. A special focus is                     given on the influence of light, heat and moisture on materials. How are they measured? How can their               impact be estimated?

10:30 – 11:15

Part 2: Photooxidation and stabilization mechanisms

              In this section the most important chemical degradation pathways are described. What effect does                     solar radiation have on materials? How can it be controlled or avoided?

11:15 – 11:30

Coffee break

11:30 – 12:30

Part 3: Validating Operation of Laboratory Weathering Instruments.

              Evaluating weathering instrument performance is a common concern. Here we show what to do if an                 instrument performs out of it specification.

12:30 – 13:30

Lunch break

13:30 – 14:30

Part 4: Correlation
              Mathematical/statistical procedures are described on how to compare weathering results from                             different exposures. This is an important step in the validation of weathering experiments.

14:30 – 14:45

 Coffee break

14:45 – 15:30

Part 5: Acceleration
              Technical solutions on how to accelerate weathering experiments are described on day one (FoW I) of                 this seminar. Here is described what has to be considered to get reliable and significant results from                   accelerated testing and on how to validate reciprocity.

15:30 – 16:00

Case study

16:00 -16:30

Final Discussion
