Objectives
To discuss the principles of qualification of systems and
equipment, with specific focus on:
 The different stages of qualification
 Requalification and
 Qualification of “in use” systems and equipment

Principle
 Systems and equipment: Appropriately designed, located,
installed, operated and maintained
 Critical systems and equipment – should be qualified
 May include, where appropriate:
– Water purification systems, air-handling systems,
autoclaves, coating machines
 Continued suitable performance needed
– Why? To ensure batch-to-batch consistency
1.1 – 1.3

Scope
 Guidelines describe the general aspects of qualification for
systems and equipment
 Normally qualification would be applicable to critical systems
and equipment whose performance may have an impact on the
quality of the product
2.1 – 2.2

Validation
General
 Qualification policy for systems and equipment
 To include instruments used in production and quality control
 New systems and equipment: All stages of qualification
applicable (DQ, IQ, OQ and PQ)
 In some cases: Not all stages of qualification may be required
– e.g. electrical supply systems
3.1 – 3.4

Validation
General (continued)
 Systems: Qualified before equipment
 Equipment: Qualified before routine use
 Systems and equipment: Periodic requalification, as well as
requalification after change
 Certain stages done by the supplier or a third party
 Maintain the relevant documentation, e.g.
– standard operating procedures (SOPs), specifications and
acceptance criteria, certificates and manuals
3.5 – 3.9

Slide 8 of 27
August 2006
Validation
General (continued)
 Qualification should be done in accordance with predetermined
and approved qualification protocols
 The results of the qualification should be recorded and reflected
in qualification reports
 The extent of the qualification should be based on the criticality
of a system or equipment, e.g.
– Blenders, autoclaves or computerized systems

Validation
Design qualification
 User requirements should be considered when deciding on the
specific design of a system or equipment
 A suitable supplier should be selected for the appropriate
system or equipment (approved vendor)
4.1 – 4.2

Validation
Installation qualification
 Correct installation as per plan and protocol
 Normally advised to prepare requirements for calibration,
maintenance and cleaning at this stage
 Identification and verification of all system elements, parts,
services, controls, gauges and other components
 Calibrate the measuring, control and indicating devices
– against appropriate, traceable national or international
standards
5.1 – 5.4

Validation
Installation qualification (2)
 Documented records for the installation
– installation qualification report
 Indicate satisfactory installation
 Include details, e.g.
– The supplier and manufacturer
– System or equipment name, model and serial number
– Date of installation
– Spare parts, relevant procedures and certificates

Validation
The handout shows a typical format for
"An installation qualification protocol / report"
 It reflects the minimum information that should be included
 This is an example – and should be used as such
 Specific formats need to be designed for a specific system or
piece of equipment

Validation
Operational qualification
 Systems and equipment should operate correctly – operation
verified as in the qualification protocol
 Studies on critical variable to include conditions encompassing
upper and lower operating limits and circumstances (i.e.
“worst case conditions”)
 To include verification of operation of all system elements, parts,
services, controls, gauges and other components
6.1 – 6.3

Operational qualification (2)
 Documented records (Operational qualification report)
 Finalize and approve SOP (operation)
 Training of operators provided – training records
 Systems and equipment released for routine use after
completion of operational qualification, provided that:
– All calibration, cleaning, maintenance, training and related
tests and results were found to be acceptable

Performance qualification
 Systems and equipment should consistently perform in
accordance with design specifications – verified in accordance
with a performance qualification protocol
 Documented records – performance qualification report
 Show satisfactory performance over a period of time
 Manufacturers to justify the selected period
