*The pipes under ‘c’ and ‘e’ tested in accordance with IMO Res. 753(18).
Other applications are subject to case-by-case approval.
Deck and bulkhead to be insulated with approved insulation according to classification covering the edge of the steel
frame. See insulation drawings specified in the Type Examination Documentation. A-0 RS X penetrations are to be
insulated as for class A-60.
Cold service piping insulated with Armaflex rubber insulation layer may be used with approved penetrations but is to be
locally interrupted through the penetration system.
Please note Installation instruction for Roxtec RS X attached through expansion: Aperture irregularities are acceptable
within min and max diameters. (Max Ø = Min Ø + 2mm)
Penetrations through structural divisions should not impair the structural strength of the division.
Special consideration should be given to bulkheads and decks with high stress locations
(IMO MSC.1/Circ.1488).
The insulation materials used have to be approved according to the UK Marine Equipment Regulation and bear the
Mark of Conformity.
Each product is to be supplied with its manual for installation and maintenance.
