3.7.4.1.2 Limitations to repairing
It is allowed to repair the inflatable parts with patches up to a percentual surface of 25% of the total surface of
the panel. In any case, for each buoyancy chamber, when the buoyancy chamber consists of several panels
(see buoyancy tubes of decagonal liferafts), there should not be more than fifteen patches.
As far as patches are concerned, the following limitations are given on the ratio between different dimensions of
the patches:
•
Maximum ratio between lenght of the patch and diameter of the panel = 25 %.
•
Maximum ratio between the area of the patch and the area of the panel = 12.5 %.
• Maximum ratio between the lenght of the patch and the lenght of the panel = 50 %.
•
Maximum ratio between the peripherical length of the patch and the circumference of the panel = 40 %.
• Maximum ratio between the length and the depth of the patch = 3 %.
3.7.4.2 REPAIRING OR REPLACING THE STUDS
Repairing on studs may be:
•
Replacing the stud.
• Glueing the weld.
The procedure to be followed in both cases is the same:
1.
Remove the stud from the panel with pliers.
2. Clean both the base of the stud and the base of the panel with M etil E thyl K etone.
3. Glue onto the panel a circular fabric patch having the same diameter as the base of the stud + about 80
mm.
4.
Wait the time necessary for the patch to stick firmly to the panel, then glue the stud to the panel on top of
the patch.
