Classification of glazed bulkheads: UK21/F024
Adopted EU recommendation FIRE-077. UK approved recommendation on the correct classification of a glazed bulkhead (bulkhead made of glass partitions).
Question
Should a glazed bulkhead (bulkhead made of glass partitions) be considered under item UK/3.11a or UK/3.11b, or be considered a window under item UK/3.25?
Recommendation
Glazed bulkheads shall be approved under UK/3.11b, not UK/3.11a or UK/3.25.
Glazed bulkheads of other than B-0 class shall be tested with five thermocouples placed on each glass section, corresponding to the way a bulkhead panel is temp. monitored.
For glazed bulkheads, it is not mandatory to apply the window-specific requirement of placing temperature sensors at mid-length of each of the four perimeter edges along the perimeter of the glazed bulkhead, but temperature sensors should be placed at joints between the glazed bulkhead sections (i.e. on mullions and transoms), corresponding to the placing of temperature sensors on the joints between bulkhead panels.
The optional hose stream and thermal radiation tests for windows are not mandatory for glazed bulkheads.
Glazed bulkheads are not entitled to have USCG Approval number.
