10. Pressure tests
In accordance with ISO 5208 / EN 12266 and API 6D / API 598 hydros-
tatic strength tests using 1.5 times the nominal pressure (housing) are
carried out at the factory. The complete valves are either tested hydrosta-
tically using the indicated valve nominal pressure or an air tightness test
using 6 bar is carried out.
For system specific pressure tests carried out by the operator the nomi-
nal pressure must not exceed 1.1 times of the value specified on the type
plate (also refer to section 2 “Marking”). For test pressures higher than
“1.1 x PN” there is the risk of damage to the PTFE (polytetrafluorethyle-
ne) seal. Higher pressure tests only after authorisation by AZ.
