Annex 15 requirements for the qualification of equipment

What Annex 15 covers

Annex 15 is the part of the EU GMP dedicated to qualification and validation. It does not only concern equipment: it covers the qualification of plants and utilities, the validation of processes, of analytical methods, of transport systems, and change management. Here we focus on the requirements that touch the qualification of equipment.

The key requirements

1. Validation Master Plan (VMP)

Qualification and validation activities must be planned. The VMP describes the strategy, the scope, the responsibilities, the format of the documents and the general acceptance criteria. It is the umbrella document from which the individual protocols descend.

2. User requirements (URS) as the starting point

Every qualification starts from the User Requirements Specification: they define what the equipment must do and under which conditions. The URS are the baseline against which design (DQ) and performance (PQ) are verified. Without clear URS, qualification has no yardstick.

3. Phased and risk-based approach

Annex 15 provides for the articulation into DQ, IQ, OQ, PQ, with the possibility of combining phases when justified. The extent of the tests is modulated according to the risk to product quality: it is the same principle that GAMP5 formalizes in the V-model, which we discuss in the IQ/OQ/PQ qualification guide.

4. Predefined acceptance criteria

The acceptance criteria must be established before the execution of the tests. Every deviation is a deviation to be documented and assessed, not a detail to be silently corrected.

5. Requalification and change control

Annex 15 requires that the qualified status be maintained over time: modifications go through change control, which assesses the impact on validation and establishes any requalifications. Periodic requalification follows a risk-based logic.

6. Calibrated and traceable instrumentation

Qualification tests are performed with calibrated and traceable measuring instrumentation. It is the point of contact with metrology: the data loggers of a thermal requalification, for example, must have traceability guaranteed through ACCREDIA-accredited laboratories.

A frequent mistake

Many sites treat qualification as a package of documents to produce once and archive. Annex 15 asks for the opposite: a maintained status, where every modification calls the validation back into question. The difference shows in an audit — a perfect qualification dossier "frozen at day one" does not hold up if in the meantime the equipment has been modified without change control.
