It shall be ensured that the manifold provided has been subjected to the hydro test pressure of 25 kgf/cm2 at least for a minimum period of 30 min and inspected by the authorized agency or the distribution company.

Part of the Installation working at cylinder pressure to be tested at 25 kgf/cm2 or 1.5 times the developed pressure at 65°C, whichever is more.
Downstream part of the installation after PRV to be tested at one and a half times the maximum outlet pressure that may be given by an adjustable PRV or 2 kgf/cm2, whichever is more.

Portions of installation not subjected to cylinder pressure but carrying gas at pressure more than 30 gf/cm2 to be tested at 2.5 times the working pressure for 2 min.

Portions of installation subjected to gas pressure of 30 gf/cm2 or less, to be tested at 2.5 times the working pressure for 2 min.

Note: The standard recommends conducting a pressure test for a duration of 2 minute. However, we believe this may be a typographical error. Given the critical safety implications of pressure testing, a duration of 2 hours would be more appropriate and aligns with standard industry practices.

Naked flames shall never be used for checking gas tightness of the installation. Leak detection should be done using soap solution or similar material.

The gas piping system should be carefully tested for ensuring gas tightness.
