a) feed pump;
b) control and safety device for feed pumps;
c) service tank;
d) service vessel;
e) safety shut-off device;
f) isolating valve;
g) quick acting valve;
h) switch-over valve;
i) forced switch-over valve;
j) check valve;
k) pressure compensating device;
l) discharge valve;
m) pressure reducer;
n) filter;
o) meter;
p) de-aerator;
q) anti-siphon safety device;
r) insulating device;
s) pressure gauge;
t) vapour/air separator;
u) pressure control path;
v) pressure retaining device;
w) remote acting fire safety valve;
x) pipe;
y) pipeline connections;
z) component within pipes;
aa) combined component;
bb) withdrawal device.
Not covered by this document are items belonging to the consuming unit (e.g.: heating/cooling appliances in buildings) and items used for the mounting and support of components.
Not covered by this document are items with the intended use of gas for building heating/cooling systems and any items of heating networks.
Not covered are items used for drainage (including highways) and disposal of other liquids and gaseous waste, supply of oil and other liquids, supply of gases, pressure and vacuum systems, communications, sanitary and cleaning fixtures and storage fixtures.
