4.10.4 Blast testing
The high pressure inflation hose, attached to the inlet valve connection,
must be pressure tested as follows:
NOTE:
This Blast test must be performed using the purpose-
made Blast test valve / Syphon tube (see TABLE 505).
If a TPED compliant cylinder is to be used, then it is
recommended that this is done so in conjunction with
a 16.9 liter cylinder – bare cylinder (P/N 58-41947001),
description CYLINDER M BARE 16.9lt 250bar.
This cylinder for blast testing should be charged with
11.26kg CO
2
+ 0.36kg N
2
.
The cylinder valve should be installed into the cylinder
with 2 turns of PTFE tape & torqued to 240Nm (177ftLb)
+10% -0%. This blast test cylinder assembly is not
suitable for transportation in USA/Canada.
NOTE:
If a USDOT compliant cylinder is to be used, then it is
recommended that this is done in conjunction with a
960 cu.in. cylinder – bare cylinder (P/N 58-42117001). This
cylinder for blast testing, should be charged with 8.80
kg CO
2
+ 0.44 kg N
2
.
The cylinder valve should be installed into the cylinder
with 2 turns of PTFE tape & torqued to 220 Nm +10% /
-0 Nm.
A cylinder adaptor is required to fit the valve onto the
cylinder, (see TABLE 505).
(a) The Blast kit required is listed in TABLE 505.
CAUTION:
ENSURE THE SAFETY PIN IS IN PLACE AT ALL TIMES. IT
SHOULD ONLY BE REMOVED FOR THE PERIOD OF THE
BLAST TEST.
(b) Disconnect the high pressure (HP) inflation hoses, which are
currently fitted to the liferaft, from the operating head.
(c) Connect one HP hose at a time, to the fitting on the blast test
cylinder valve, (FIGURE 511/512). The correct torque value for
this hose attachment can be found in Chapter1, TABLE 101,
Torque settings.
