— WHAT IS AUTOCLAVE VALIDATION —
Autoclave / Sterilizer Validation —
Why It Is GMP Mandatory
Autoclave validation proves that your steam sterilizer consistently achieves Sterility Assurance Level (SAL) of 10⁻⁶ at every point of the load under defined cycle parameters — and that this is documented with the evidence required to satisfy regulatory inspectors.
Mandatory under EU GMP Annex 1 (2022) and Schedule M India
Both revised EU GMP Annex 1 (2022) and India's Schedule M (2023) require full DQ/IQ/OQ/PQ qualification with temperature distribution and heat penetration studies before any autoclave can be used in pharmaceutical manufacturing.
F0 value proves sterility without culture testing every batch
A validated sterilization cycle with a documented minimum F0 value provides overkill assurance — your product is sterile based on engineering evidence, not batch-by-batch biological indicator testing.
A failed sterilization cycle = batch rejection and investigation
An unvalidated autoclave or a cycle failure means the entire batch must be rejected, a GMP deviation opened, root cause investigated, and regulatory notification potentially required — far more costly than one validation.

— OUR PROCESS —
Autoclave Validation Process — Step by Step
Every autoclave validation follows the GMP lifecycle per EU GMP Annex 1 (2022), EN 285, and ISPE Steam Sterilization Baseline Guide.
Design Qualification (DQ)
Review autoclave specifications, chamber size, jacket pressure, cycle parameters, and utility requirements. VMP drafted with scope, acceptance criteria, and sterilization cycle definition.
Installation Qualification (IQ)
Verification that autoclave, steam utilities, safety valves, control system, and recording instruments are installed per approved drawings and manufacturer specifications.
Operational Qualification (OQ) — Temperature Distribution
Empty chamber temperature distribution study with 12+ calibrated data loggers at defined positions. Minimum 3 consecutive runs per cycle type. F0 or time-temperature acceptance criteria verified.
Performance Qualification (PQ) — Heat Penetration
Loaded heat penetration study at worst-case load configuration. F0 calculation for sterilization cycles. Bowie-Dick test for porous load autoclaves. Vacuum leak test per EN 285.
Deviation & CAPA
Any OOS temperature readings, failed Bowie-Dick tests, or F0 shortfalls documented as deviations with root cause analysis and CAPA. Retesting performed before final sign-off.
Validation Report Issued
Complete validation report with DQ/IQ/OQ/PQ protocols, raw data, F0 calculations, Bowie-Dick results, deviation log, and conclusion — GMP-ready within 7 days.

— NON-GMP QUALIFICATION —
Autoclave Qualification for Non-Pharma Facilities
Not every autoclave requires full pharmaceutical GMP DQ/IQ/OQ/PQ. For hospitals, laboratories, food processing, and research environments — Prism offers routine autoclave qualification and temperature mapping at cost-effective pricing with the same NABL-calibrated instruments.
NABL-Traceable Instruments
All data loggers are NABL CC-2480 calibrated regardless of whether the qualification is GMP or non-GMP.
Faster Completion
Non-GMP temperature mapping completed within 3–5 days. GMP DQ/IQ/OQ/PQ packages take 7–10 days.
Flexible Scope
Choose only the tests you need — temperature mapping only, or full DQ/IQ/OQ/PQ — priced accordingly.
Onsite — No Shutdown
All testing done at your facility with portable instruments. Autoclave not removed from service.
Onsite Coverage
