Hydrostatic Testing

Hydrostatic Testing of Fire Suppression Cylinders

Regular Hydrostatic Testing of Fire Suppression Cylinders is required under all relevant international standards, including the Australian and ISO Standards. The requirement for testing exists due to the potential for rapid decompression (aka explosive discharge) of gases due to failure of containers if not maintained correctly.


Fire Systems Products own and operate Australian standards approved test station No.847 for the inspection and testing of Gas cylinders and vessels. We handle all types of Gaseous fire suppression cylinders with on-site reclamation and testing facilities for many gas types.

Don't be told your system is outdated; let us put another 5 or 10 years of life back into your Gaseous fire suppression system by conducting the mandatory 5 yearly or 10 yearly hydrostatic pressure test.

What is Hydrostatic Testing?

Hydrostatic testing is a way in which fire suppression cylinders can be tested for strength and leaks. The test involves removing and reclamation of the gas, filling with water, and pressurising the container to the required specifications. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. Our qualified inspectors can visually identify the location of a leak during the test.

A Cylinders strength is tested by measuring the permanent deformation of the container. Hydrostatic testing is the most common method employed for testing pressure vessels. Using this test helps maintain the safety standards and ensure durability of a cylinder over time.

Newly manufactured pieces are initially qualified using hydrostatic testing methods. They are then re-qualified at regular intervals by conducting further hydrostatic pressure tests. Testing pressure vessels for transporting and storing gases is essential because such containers can explode (rapid decompression) if they fail under pressure.

Ensure your Gaseous fire suppression system is compliant and, more importantly, safe for use. If your company maintains Gaseous Fire Suppression Systems, ensure your technicians know when the hydrostatic pressure tests are due and contact FSP on +61 (02) 8004 9156 to schedule the test.
