This document summarizes the validation process for a liquid filling and sealing machine. It discusses the key stages of validation including user requirement specification, design qualification, installation qualification, operational qualification, and performance qualification. It provides details on each stage, describing the objectives and tests performed at each stage. For example, performance qualification involves weight variation testing, filling volume accuracy testing, particle contamination testing, leak testing, and oxygen content testing to validate the machine's performance under working conditions. The overall validation process helps ensure the machine operates as intended and produces product meeting specifications.
5. • The previous figure depicts the most commonly
used approach to the qualification process as
used in the pharmaceutical industry
• It shows a pyramid, which is the best way in
which to plan a qualification/validation project
• Investing more time in the first phases will save
time and money in later and critical phases

6. Who should do Equipment Validation?
• The vendor or the user ?
— User has the ultimate responsibility for the accuracy of
the analysis results and also for equipment qualification
— DQ should always be done by the user
— While IQ for a small and low cost instrument is usually done
by the user, IQ for large, complex and high cost instruments
should be done by the vendor
— OQ can be done by either the user or the vendor
— PQ should always be done by the user because it is very
application specific, and the vendor may not be familiar with
these
— PQ should be done on a daily basis

10. Validation Protocol
• The entire process of equipment validation is
designed in the form of certain documented
formats or protocols
• This helps in systematizing the study of
equipment validation
• A validation protocol prepared by engineer or
validation specialist
• The protocol sections contain required
procedures and forms
10
11. User Requirement Specification
• The user of the equipment has certain
requirement about the equipment which he
wants to use
• Some of the general requirements may be
stated in the form of certain parameters like…
– Size of equipment
– Speed of equipment
– Availability of spares, change part, immediate service at
reasonable cost
11
12. – Low sound generation
– Lesser breakdowns
– Materials of construction
– Auto control system
• This requirements are generally discussed
with the suppliers and based on this
discussion the selection of the equipment is
done
12
13. For example,
• In ampoule filling machine, a delivery tube
provided for repetitively forcing a measured
volume of liquid through the orifice of delivery
tube designed to enter the constricted opening
of container
• The size of delivery tube depend on ..
– the opening of container
– the viscosity & density of liquid
– speed of delivery desired
13
14. D.Q. and its Certification
• If we are going to purchase an standard
equipment then the preparation of D.Q. dose
not become very important because we are
accepting the manufacturer's design as it is
• However, if a particular equipment is to be
fabricated as per our requirements then the
detailed D.Q. document become very
important and essential
14
15. • It is advisable to work out the detailed
equipment specifications by sitting together
with the equipment manufacturer
• It may also be advisable to perform Factory
Acceptance Test (FAT) at the manufacturer’s
premises before dispatch of the equipment to
the purchaser
15
16. Installation Qualification
• “Installation qualification establishes that the
instrument is received as designed and
specified, that it is properly installed in the
selected environment, and that this
environment is suitable for the operation and
use of the instrument”
16
17. • I.Q involves,
– Verification of approved purchase order
– Verification of invoice
– Check manufacturer and supplier
– Verification of model number and serial number
– Checking for any physical damage
– Confirm location and installation requirements as per
recommendation of manufacturers
– Verify that the utilities required are available
– Installation shall be conducted as per instructions provided
in the manual
17
18. • Ensure all relevant documentation is received
like,
− User manual
− Maintenance manual
− List of change parts
− Electrical drawings
18
19. Operational Qualification
• O.Q. is verification of performance of the system without
load
• O.Q. section details the tests to be performed on the
equipment to document that it operates correctly
• O.Q. involve,
– Verification of alarm control
– Perform calibration requirements identified in the manual or
established by the validation team
– Operate the equipment at low, medium, and high speed as per
operations manual to verify the operating control
– Verify that all switches and push buttons are functioning
properly
– Establish procedures (SOP) for operation, maintenance, and
calibration
– Establish training program for relevant staff
19
20. Performance Qualification
• P.Q. is verification of performance of system with
load
• Filling studies will be run on all containers and fill
levels
• The containers will be filled in triplicate runs
• If a placebo is used, it should have similar physical
characteristics (viscosity, density, foaming) to the
actual fill materials
• The study should be run at minimum, maximum and
intermittent speeds (in terms of ampoules/minute)
• The filler must handle the containers without
damage and without jams
• Accuracy and precision must meet specifications
20
21. • P.Q. of ampoule filling and sealing machine
involve,
a) Wight variation test
b) Filling volume accuracy
c) Particle Contamination
d) Leaker test
e) Oxygen content
21
22. a)Weight variation test :
– In the absence of specific criteria, weight variation
must conform to USP
– In summary, all 10 units must be within 85.0 to
115.0% of target content, with a %RSD ≤ 6.0%, or
not more than 1 of the 30 units outside of the 85.0
to 115.0% and no units outside of 75.0 to 125.0%,
with a %RSD ≤ 7.8%
22
23. b)Filling Volume Accuracy:
The filling accuracy should be within ±% of the
adjusted and desired filling volume in
accordance with the machine specification.
eg.
– Attention limit: ±1%
– Action limit: ±2%
23
24. c) Particle Contamination of Ampoules during
Filling & Sealing Procedure:
– Ampoules should be filled with water for injection
and afterward be inspected on the contamination
with particles (particle classes: ≤10 μm and ≤25
μm).
– The inspection can be performed with a particle
counter.
24
25. d)Leaker test:
– Should capillary pore or tiny cracks be present,
micro-organisms or other contaminants may enter
the ampoule, or the content may leak outside.
– Leaker usually detected by submerged ampoule in
a deeply colored dye solution (usually 0.5 to 1.0%
methylene blue).
– Limitation is that capillaries of about less than 15
um not detected by this method.
25
26. e) Oxygen content,
– If the filler produces a nitrogen purge, the
headspace gas should be analyzed for oxygen
content
26
27. Requalification
• Requalification of systems and equipment should
be done in accordance with a defined schedule
• The frequency of requalification may be
determined on the basis of factors such as the
analysis of results relating to calibration,
verification and maintenance
• There should be requalification after changes
• The extent of requalification after the change
should be justified based on a risk-assessment of
the change
