Excerpt of ISO 7165 – Chapter 9.2.5

Cylinder cycling test procedure

A minimum of two cylinders shall be tested.

An extinguisher cylinder shall sustain, without rupture, 5 000 cycles from 0 to the test pressure (pt) and back to 0 at the rate of 6 cycles/min. At the conclusion of testing, the cylinder shall be subjected to and comply with the burst test.

Pressure cycling test of extinguisher cylinder

to subjected 5500 cycles of pressure load alternation with a rate of 6 cycles /min
recorded by a digital counter

Ø     With automatic pressure increase and decrease from 0 to 35 bar.

Ø     The system works with water pressure with maximum pump pressure of 150 bar

Ø     The master gauge have range from 0 – 40 bar and a accuracy of 0,25% of the
 total range and a automatic cut of after reach of the pre adjusted test pressure.

Ø     With tilting support for easy handle and thread connection for pressure cycling test
 of 1 Cylinder at time with a maximum size of diam. 200 mm / and a maximum
 length of 600 mm
