normal operation and expected malfunction.
b. Electro static charges
The only non-conductive part of the
equipment is the plastic handle grip. The
surface resistance of the material does not
exceed 1G
Ω
at (23 2) C and (50 5)%
relative humidity. The equipment also
designed and constructed with an electrical
continuity design between ball, stem and
body. Any occurrence of efficient electro
static charge will be earthed through the pipe
line earthing.
c. Containing light metals
Materials used in the construction of external
parts do not contain light metals more than
7.5% of magnesium.
d. Equipment was tested in factory according to
high pressure leakage test before delivery. It
will not release flammable gases to explosive
atmosphere outside the equipment.
e. The internal parts, such as seals and packing
can be adversely affected by some solvents.
List of solvents which are known to be
compatible with the seal and packing
material are provided in the corrosion data
information.
f. The equipment also conforms to Pressure
Equipment Directive (97/23/EC), The
mechanical strength of the structure can
withstand the hazard cause by internal
pressure.
