The notch impact test determines the material toughness with regards to the temperature. We use a pendulum machine according to DIN 51222 of the Material Testing Institute (MPA) in Dortmund, which has been inspected and approved according to DIN 10045 Part 2 for a testing range up to 300 J.
all source materials according to DIN 50115
Weld samples according to DIN 50111 & DIN 50122
The choice of material must guarantee a sufficient impact energy for the whole applicable temperature range. For some materials the impact energy drastically drops with low temperature (starting from -10°C).
