3 Meter Cube Smoke Density Apparatus

  • BS 6853 Appendix D
  • , IEC 61034-1&2
Motis 3 Meter Cube Smoke Density Apparatus is used to measuring smoke emission when materials are burnt under defined conditions.
The specimen is exposed to a standard fire source which contained in a tray underneath, in a 27 cube meter test chamber. During the test, the generated smoke mix by a table-type fan and is detected by a photometric system.
It’s one of major test procedure for classification of cables in European. As well, Relating to BS 6853 Code of practice for fire precautions in design and construction of passenger carrying trains​.
