Class A
Visible seal with high requirements for the finish.
The material must have been applied liberally but evenly. There must be no areas where excess sealant has gathered.
Use a rubber putty knife to smooth the surface.
See panel section A for the appearance of the bead.
Class B
Visible seal with lower requirements for the finish.
The material should be liberally but evenly applied.
Lines and minor pitting is acceptable.
The sealant must not have been applied too thickly.
The dimension of the bead must be as in panel section B.
B1 = minimum 0.5 mm, maximum 2.0 mm.
B2 = minimum 4.0 mm, maximum 10.0 mm.
B3 = minimum 2.0 mm.
B4 = minimum 2.0 mm, maximum 4.0 mm.
Class D
Seal with no requirements for the finish.
The sealant must be liberally applied.
Minimum material thickness = 0.5 mm.
Lines, lumps and pools of up to 5 mm are acceptable.
The dimension of the bead must be as in panel section D.
