Specifications

Technical data.

IMO ApprovedYes
Inspection

Inspector Detail

Common issues

  • Panel joint sealant/gasket degradation compromising fire division integrity
  • Core insulation moisture ingress reducing fire/thermal performance
  • Surface delamination or facing damage from mechanical impact
  • Corrosion of the support grid/suspension system in humid spaces (e.g. galleys, wet units)
  • Unauthorised penetrations (cables, ducts) made without maintaining the B-class rating
  • Loss of certification markings making panel type/rating unverifiable after refit

Inspection checklist

  • Visual check of panel surface for damage, delamination or discolouration
  • Inspect joints and seams for gaps or missing sealant that would compromise B-class integrity
  • Check support/suspension grid for corrosion or loose fixings
  • Verify any penetrations (lights, speakers, ducting) retain approved B15 detailing per drawing
  • Confirm certification/type marking is present and matches the approved fire control plan
  • Check for moisture ingress or staining indicating core degradation

Service intervals

General condition inspectionat Annual Survey / internal fire safety rounds
Detailed check of joints/penetrations after refit or cable/pipe workimmediately after such work, then reviewed at Annual Survey

Critical spares

  • Matching B15-rated panel/insert of the approved type, for replacing a damaged panel
  • Fire-rated joint sealant/mastic of the maker-approved type
  • Suspension grid and support bracket fixing hardware

Safety

  • Unauthorised penetrations or removal of panels without maintaining B-class detailing compromises the fire division integrity of the accommodation
  • Damaged panels reduce fire/smoke integrity of escape routes where fitted in corridors/stairways
  • Panels removed for access or refit work must be reinstated with correct B15 detailing before the space is left unattended, otherwise the fire division is effectively open

Class survey

B-class divisions (here B15, i.e. 15-minute fire integrity) are verified against the ship's approved fire control plan at Annual and Renewal Survey; class checks that penetrations, joints and any modifications since build or last survey retain the certified fire rating, and that the type approval marking corresponds to the material actually fitted.
