IV
Installation Verification
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
Documented confirmation that a system is installed as designed — components, instruments, piping, services and materials of construction checked against the approved drawings and specifications — performed within a verification-based C&Q programme, where it does the job IQ does in a traditional one.
Installation verification asks the same question as installation qualification: is what was built what was designed? The difference is how the evidence is produced. Under the ASTM E2500 approach, installation checks carried out during commissioning under adequate control — by competent people, to approved acceptance criteria, recorded to good documentation practice — can serve as the verification, instead of being repeated in a separate IQ protocol.
Scrutiny follows risk. The installation of critical design elements — a material of construction, a slope, an instrument range, a filter — is verified with quality-unit oversight; aspects with no bearing on product quality are verified to good engineering practice. That split is what makes the approach faster without making it weaker.
“IV” is a practice label. EU GMP Annex 15 still names the stage installation qualification and lists what it should include, and ISPE’s own guidance on its C&Q guide advises not getting hung up on labels such as IV and OQ. Whatever a site calls it, the evidence has to cover what Annex 15 §3.9 asks of an IQ.
- —Checks the as-built installation against approved drawings and specifications.
- —Covers components, instrumentation, piping, services and materials of construction.
- —Critical design elements verified with quality oversight; the rest to GEP.
- —Commissioning checks done under adequate control can count, instead of a repeat IQ.
- —Must still satisfy what EU GMP Annex 15 expects of installation qualification.
EU GMP Annex 15 (2015) §3.8–3.9 (installation qualification: correct installation against engineering drawings and specifications, supplier instructions collected, instruments calibrated, materials of construction verified); ASTM E2500-25, which uses verification as its umbrella term; ISPE Baseline Guide Vol. 5, Commissioning and Qualification (2nd ed., 2019).
