INSPECTION AND CHECKING
MANUAL No.
9112
C. See Chapter 1, Table 7 for the working pressure of the cylinder. Its valid period is
3 years. Any overdue cylinder shall be subjected to a hydraulic test of 1.5 times its
working pressure. After test, the qualified cylinder shall be steel stamped with the
date of the hydraulic test.
D. The external and internal condition of the cylinder must be checked in
accordance with SOLAS and DOT regulations. This standard gives the limits for
surface damage. If the damage is more than the limits, reject the cylinder.
E. Cylinders that have been submerged in water, i.e. those attached to liferafts
that have been used in an actual emergency, must be returned to the cylinder
manufacturer (or an approved agent) for reconditioning and re-test before reuse.
4. Inspection of non-return Inlet Check Valve
A. Check the one-way function of the valve and inspect the spring for any rust. If it does
not function, replace the spring, the gasket, or even the whole valve.
