German railway standard for 19" subracks in rolling stock - resistance to shock and vibration.
BN 411002 is one of the German Federal Railways standards (Bundesbahn-Norm) specified for 19" subracks and modular structures installed in rail vehicles. Manufacturers declare it together with BN 411003 for heavy-duty versions intended for operation under continuous vibration and shock.
In railway subrack data sheets, BN 411002 is listed alongside IEC 61587-2 (seismic testing of cabinets and racks), EN 50155 and the French NF F 60-002 and NF F 67-012 standards. The publisher does not make the content of the standard or its test levels publicly available - this website presents only information confirmed by manufacturer data sheets and industry publications.
A BN 411002 and BN 411003 declaration in the data sheet of a 19" subrack indicates a reinforced design for vibration and shock in a vehicle. Data sheets do not state acceleration levels, frequency ranges or test duration - obtain the manufacturer's test report for the project documentation.
