Short answer: Validate a new autoclave before it touches a patient load: confirm the installation, run three consecutive cycles with a biological indicator in a process challenge device, add a Bowie-Dick test on pre-vacuum units, and file the results with the installation paperwork. Validation is a one-time proof that the unit performs; routine monitoring is the daily evidence that it still does.
For the biological side, CliniEco supplies a 
24-hour self-contained biological indicator in packs of 50 and a 3-hour fluorescence readout version for clinics that cannot wait a day for a result. The 3-hour format matters during validation, because a failed first cycle should be found the same afternoon, not the next morning.
What are the steps in validating a new sterilizer?
- Installation check — utilities, drain, door seal, chamber clean, manufacturer commissioning complete.
- Physical checks — temperature and pressure readings against the cycle printout or gauge.
- Chemical indicators — external and internal indicators respond as specified for the cycle type.
- Bowie-Dick test — pre-vacuum units only; proves air removal and steam penetration.
- Biological indicators — three consecutive cycles, incubated with a positive and a negative control.
- Sign-off and filing — results, cycle parameters and the date recorded and retained.
Which standards apply to a Canadian clinic sterilizer?
| Element | Reference | What it covers |
|---|---|---|
| Steam sterilization practice | CSA Z314 series | Facility requirements, cycles, monitoring and records |
| Biological indicators | ISO 11138 series | Spore strains, population, performance |
| Chemical indicators | ISO 11140-1 | Classes 1 to 6 and what each proves |
| Bowie-Dick test | ISO 11140-5 Type 2 | Air removal in pre-vacuum cycles |
| Packaging | ISO 11607 series | Pouches, rolls and sterile barrier systems |
What does a failed validation cycle mean?
Stop. Do not release loads. Read the indicator per the manufacturer's instructions, check whether the failure is procedural (overloaded chamber, wrong cycle, pouch placed against the drain) or mechanical, and repeat after correcting it. Three consecutive passes are the evidence that the unit is fit for use; a single pass after a failure is a data point, not a validation.
What records should be kept after validation?
File the commissioning report, the three biological indicator results with controls, the Bowie-Dick result, the calibration certificate and the date the unit entered service. Routine daily records then sit alongside them in date order. In Ontario the RCDSO requires a biological indicator for each sterilizer on every day it is used — daily monitoring, not weekly — and inspectors read the validation record and the routine log as one story.
Download the printable validation and load log, run the sterilization self-check, and ask a compliance specialist before signing off a new unit. Clinics setting a monitoring programme can request a 5-pack biological indicator sample to cover the validation week.

Frequently Asked Questions
How many test cycles does a new autoclave need before first use?
Run three consecutive cycles with a biological indicator in a process challenge device, and for a pre-vacuum unit add a Bowie-Dick test, before the first patient load.
Who can validate an autoclave in a Canadian clinic?
The clinic can run the biological and chemical tests itself; a service provider is used for calibration and for repairs that change chamber performance.
How long do validation records need to be kept?
Keep them for the retention period set by the provincial college or accreditation body that governs the clinic, and keep the first validation separate from routine logs.
