They should be either removed,or Te:c 1'at 1'�s� Isolated from the lest section to avoid possible 3 0.10 0.15 0.1s damage,or failure of these devices.

For pressure piping systems the maximum 8 0.50 1.0 1.5 allowable test pressure Is 1-1/2 times the 10 0.75 1.3 2A system design operating pressure at the lowest 12 1.1 2.3 3.4 point in the section under test,provided dw,. test pressure limiting components or devices 14 1.4 2.9 4.2 have been isolated,or removed ftow the test 16 1.7 3.3 5.0 Section. 1s 2.2 4.3 6.5 • If a lower pressure rated device or component 20 2.8 5-5 8.0 cannot be removed or isolated,then the test 22 3.5 7.o 10.5 pressure is limited to the pressure rating of 24 4.5 9.9 13.5 that device. 26 5.0 10.0 15.0 • For non-pressure,low pressure,or gravity 28 5.5 11.1 16.3 flow(intermittent pressure)systems.consult 30 6.3 12.7 19.2 Plexco/Spimlite Technical Personnel to determine maximum allowable test pressure. 32 7.0 1a.3 21.5 34 9.0 16.2 243 36 9.0 18.0 27.0 Test Duration For any test pressure fYvm 1 to 1-112 times the HYDROSTATIC TESTING system operating design pressure,the total test time including initial pressurization,initial expansion.and time at test pressure,must not General exceed eight(9)hours. If the test Is not completed due to leakage,equipment failure, PIPING SYSTEM PRESSURE TESTING etc.,depressurize the test section,then allow it USING HYDROSTATIC PROCEDURES IS to"relax"for at least eight(S)hours before RECOMMENDED. The preferred testing bringing the test section up to test pressure medium is clean water,but other liquids may be suitable. The test section should be completely filled with liquid. Take care to bleed off any trapped air. While the test section is filling, venting at high points may be necessary to purge air pockets. Venting may be provided by loosening flanges.or by using equipment vents. Redghten any loosened flanges before applying test pressure.
