What is a fire extinguisher 5-year hydrostatic test record?

A fire extinguisher 5-year hydrostatic test record documents the results of pressure testing on portable fire extinguishers. AS 1851-2012 (Routine service of fire protection systems and equipment) includes a five-yearly service for portable extinguishers (clause 10.4.3). What that service involves, and whether the cylinder itself is pressure tested, depends on the extinguisher type, so confirm with your service provider which test applies to each unit. The test verifies the structural integrity of the cylinder under pressure.

The test involves depressurising and discharging the extinguisher, conducting a thorough internal inspection for corrosion or pitting, then filling the cylinder with water and pressurising it to the specified test pressure. The technician measures both elastic expansion and permanent expansion. If permanent expansion exceeds 10% of elastic expansion, the cylinder has deformed beyond safe limits and must be condemned and destroyed. This record captures every step of the process, from initial condition assessment through to recharging and recertification, ensuring full traceability for building compliance audits and Essential Safety Measures (ESM) annual statements.

Benefits of using this fire extinguisher 5-year hydrostatic test record

  • Five-yearly service record: documents the pressure test done at an extinguisher's AS 1851-2012 five-yearly service, where its type calls for one, as evidence for the annual fire safety statement or report your state requires.
  • Structural safety assurance: hydrostatic testing identifies weakened cylinders that may rupture under operating pressure, preventing catastrophic failure that could injure building occupants.
  • Clear pass/fail criteria: the 10% permanent expansion threshold provides an objective, measurable standard that removes ambiguity from the condemn-or-return decision.
  • Traceability and audit trail: records the technician licence number, test equipment calibration details and exact expansion measurements, creating a defensible audit trail.
  • Lifecycle tracking: links each test to the extinguisher serial number and date of manufacture, enabling accurate scheduling of the next 5-year test.
  • Site fire safety register integration: prompts the technician to update the building fire safety register immediately after testing, keeping the facility manager informed.

What to include in a fire extinguisher 5-year hydrostatic test record

This fire extinguisher 5-year hydrostatic test record covers 10 key areas:

  • Extinguisher identification: asset number, serial number, type, capacity, manufacturer and date of manufacture.
  • Technician name and fire protection licence number.
  • Pre-test external condition assessment: corrosion, dents, pressure gauge, safety pin, tamper seal, hose and label.
  • Depressurisation and discharge confirmation with empty cylinder weight.
  • Internal inspection: cylinder walls, valve threads, siphon tube, internal coating.
  • Hydrostatic test: test pressure applied (kPa), elastic expansion (mL), permanent expansion (mL), percentage calculation.
  • Pass or condemn result with action taken.
  • Post-test recharge: correct agent, correct pressure, gauge verification, cylinder re-stamp.
  • Service tag attachment and fire safety register update.
  • Test certificate issuance confirmation.

How to use this fire extinguisher 5-year hydrostatic test record

  1. Conduct a thorough pre-test external condition assessment.: Inspect the cylinder for corrosion, dents, bulging and damage. Check the pressure gauge reading, safety pin, tamper seal, hose condition, nozzle and label legibility. Record the extinguisher type, capacity and date of manufacture. If the external condition shows severe damage, condemn without proceeding to hydrostatic test.
  2. Safely depressurise, discharge and disassemble the extinguisher.: Depressurise the cylinder safely following the manufacturer procedure. Discharge all remaining agent into an approved container. Remove the valve assembly and weigh the empty cylinder, recording the tare weight for comparison against manufacturer specifications.
  3. Perform a detailed internal inspection of the cylinder.: Use a borescope or light source to examine internal cylinder walls for corrosion, pitting, scoring and thinning. Inspect valve threads for damage. Check the siphon tube and dip tube for deterioration. Examine any internal coating or lining for delamination. If significant internal damage is found, condemn the unit without proceeding to hydrostatic test.
  4. Fill the cylinder with water and perform the hydrostatic pressure test.: Fill the cylinder completely with water, eliminating all air. Connect to calibrated hydrostatic test equipment. Pressurise to the specified test pressure and hold for a minimum of 60 seconds. Measure elastic expansion during pressurisation and permanent expansion after release. Calculate permanent expansion as a percentage of elastic expansion.
  5. Determine the result and complete post-test actions.: If permanent expansion exceeds 10% of elastic expansion, the extinguisher fails and must be condemned and destroyed by the technician. If it passes, drain and dry the cylinder thoroughly, reassemble the valve, recharge with the correct agent to the correct pressure, verify the gauge reads in the green zone, and re-stamp the cylinder with the new test date.
  6. Complete certification and update all records.: Attach a new service tag showing the test date and next due date. Update the building fire safety register with the test result. Issue a formal test certificate to the site fire warden or facility manager. Record condemned and destroyed units in the register with replacement details.

How often should you complete this checklist?

AS 1851-2012 sets six-monthly, yearly and five-yearly service for portable extinguishers, with a three-yearly item in clause 10.2.3. There is no single pressure-test interval for every extinguisher: what the five-yearly service involves, and whether the cylinder is pressure tested, depends on the type, and a CO2 cylinder is a gas cylinder with its own test regime, so ask your service provider what applies to each unit. The clock starts from the date of manufacture stamped on the cylinder, not from the date of installation. A monthly visual check between services is site practice, not an AS 1851 frequency. In MapTrack, you can set each extinguisher's test schedule against its asset record, and the assigned person gets an email in the week before each test falls due, across all your sites.

Frequently asked questions

If permanent expansion exceeds 10% of elastic expansion, the cylinder has plastically deformed and cannot safely contain pressure. It must be condemned immediately. The technician must physically destroy the cylinder, typically by drilling or cutting, to prevent it from being returned to service. A replacement extinguisher must be installed at the same location.

Hydrostatic testing must be done by a competent person (AS 1851-2012 clause 1.10) holding any licence or approval your state or territory requires, using calibrated test equipment with current certification. In NSW, inspection and testing that involves no specialist trade generally needs no licence, so check the technician's training and experience as well as any licence they hold.

The six-monthly service (AS 1851-2012 clause 10.4.1) is a visual and functional check covering gauge pressure, tamper seal, hose condition and mounting. A hydrostatic test is a pressure test that verifies the structural integrity of the cylinder itself, done at the five-yearly service (clause 10.4.3) where the extinguisher type calls for one. It requires complete discharge, internal inspection and pressurisation above normal operating pressure.

It can. CO2 extinguishers operate at much higher pressures and have thicker-walled cylinders, and a CO2 cylinder is a gas cylinder with its own inspection and test regime. Published test intervals for CO2 disagree with each other, so ask the technician who services your site what applies rather than working from one number. The test pressure for CO2 cylinders is also significantly higher.

AS 1851-2012 sets out routine service records, including records retention, in clause 1.16, and in NSW building owners must keep those records for at least 7 years. Keep the hydrostatic test certificate and test record for the extinguisher's full service life and for at least 7 years after the unit is condemned or replaced. The certificate must be available to the building owner, fire authority and certifier: it supports the Annual Fire Safety Statement (NSW) or annual essential safety measures report (Victoria), and in the ACT, records must be available to ACT Fire & Rescue within 48 hours of a request. If a cylinder is condemned and destroyed, keep the destruction record with the replacement unit's history.
