DIN 54837 Chamber
Compliance
DIN 54837, DIN 5510-2
The DIN 54837 Chamber, in accordance with DIN 54837/DIN 5510, is designed to determine the burning characteristics of railway material exposed to a wide opening gas burner flame, including damage range, smoke development, and droplet test.
DIN 5510-2 uses DIN 54837 test results for materials classification.
