New Handbook on Weathering Published

September 30, 2024 | Dr. Florian Feil

Publications

This time, I am writing on my own behalf. Over four years ago, Vincentz-Verlag asked me if I would be willing to update the German text book Kurzzeitbewitterung (also published in English as Accelerated Testing) by Ulrich Schulz, former employee of BAM, Germany. I was deeply honored, as this book has been considered the "bible of coatings weathering" for many years.

Wet or Dry Samples - Potential Source of Error in Weathering Tests

May 14, 2024 | Dr. Florian Feil

Standards

Weathering tests should not be interrupted while the samples are in the middle or end of a wetting phase. Handling or evaluating wet samples is a source of error which must be avoided.

ASTM D7869 or SAE J2527 – Which is More Appropriate?

October 16, 2023 | Dr. Florian Feil

Standards

Over ten years ago, ASTM D7869 “Xenon Arc Exposure Test with Enhanced Light and Water Exposure for Transportation Coatings” was first introduced as a new and revolutionary weathering standard for automotive and general transportation coatings. This standard is based on the careful consideration of photochemical- and moisture-related coating degradation and a hot, humid end-use environment.
