WHY TO VALIDATE?
Equipment validation is Vital for
• Safety
• Fewer interruptions of work
• Lower repair costs
• Elimination of premature replacement
• Less standby equipment
• Identification of high maintenance cost
• Reduction of variation in results
• Greater confidence in the reliability of results

WHO SHOULD DO EQUIPMENT VALIDATION?
THE VENDOR OR THE USER?
The user has the ultimate responsibility 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, and
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

EQUIPMENT QUALIFICATION
Equipment qualification / validation includes
following things :
Design qualification (DQ)
Installation qualification (IQ)
Operational qualification (OQ)
Performance qualification (PQ)

INSTALLATION QUALIFICATION(IQ)
Installation
Procedure:
After checking all the specifications as mentioned
in the selection criteria, service engineer of the
manufacturer shall be called for commissioning, if
necessary.
Authorized validation team shall carry out
installation.
Department
Head of production, QA &
engineering shall evaluate installation report
12
Conti…
Acceptance Criteria For Installation Qualification:
The equipment shall fulfill the selection criteria & its
purpose of Application.
Name of the manufacturer & supplier shall be as
mentioned in the Purchase order
The manufacturer/supplier shall provide complete
equipment manual along with the equipment
All recommended utilities of recommended
capacities are to be provided near the place of
installation
13
Conti…
Revalidation Criteria
The equipment shall be revalidated if;
Location of the equipment is changed.
There is change of spare/parts,major maintenance
or breakdown that have a direct effect on the
performance of the equipment
14
Conti…
Conclusion:
The equipment shall be considered qualified for
installation provided it meets all the parameters
mentioned in the acceptance criteria.
After receiving installation report, it shall be
evaluated
&
released
for
operational
qualification, provided installation report is
evaluated & the equipment is found meeting all
parameters of acceptance criteria
15
OPERATIONAL QUALIFICATION (OQ)
Training record
Before initiating OQ ensure that SOP for
Cleaning and operation of FBD is available.
•
Purpose: To train the qualification team for
performing OQ
16
Conti…
Procedure
Initiate the actual operation of the FBD to ensure
that machine is operating within specification.
Check the OQ parameters against their
specifications.
Observe the functioning of all controls available
on control panel
Record the observation
Perform and attach report of heat distribution
study as per ` Heat distribution study procedure’
17
Conti…
Acceptance criteria (Heat Distribution Study:)
Temperature difference between all thermocouples
and set temperature should not differ by more than
± 5 °C.
All operating inputs provided on the equipment
when tested shall-successfully comply
-meet tolerance limit
The equipment should successfully perform when
operated as per SOP
18
Conti…
Critical gauges/indicators provided on the
equipment---calibrated
The equipment when operated shall not
- produce abnormal sound
- show any discrepancy in its smooth operation.
19
Conti…
Revalidation Criteria:
The equipment shall be revalidated if;
Location of the equipment is changed.
There is change of spare/ parts, major maintenance
or breakdown that have a direct effect on the
performance of the equipment
Critical gauges shall be replaced or corrected
At normal revalidation schedule.
20
PERFORMANCE QUALIFICATION(PQ)
To check Heat Distribution by placing 10
thermocouples in geometric pattern with the FBD
Shell and empty Product Container without any
load to ensure heat distribution in the drying
chamber
Heat distribution study will be performed at 65 ±
5°C for two hour after achieving the temperature
on the controlling sensors to ensure proper heat
distribution.
21
Conti…
Procedure
After completion of OQ initiate the PQ of FBD.
The effectiveness of drying will be qualified by
determining reduction of % moisture content in
drying process.
3 batches/ lots of any product will be taken for PQ
of FBD.
At least 2.0 gm of sample is sampled for % MC
check from the top, middle and bottom trays and
will be reported
22
Conti…
In case of any deviation inform to department
head for necessary action
Document the deviation details
Deviation is acceptable or not will be decided
-if yes
-if not
23
Conti…
Acceptance criteria
The reduction in moisture content after drying
should be as per the specification in the BMR
% RSD of LOD should not be more than 6 %
The equipment should produce intended outputs
with respect to quality & quantity consistently
24
Conti…
Revalidation Criteria:
The equipment shall be revalidated if;
Location of the equipment is changed.
There
is change of spare/ parts, major
maintenance or breakdown that have a direct
effect on the performance of the equipment
At normal revalidation schedule.
25
PROCEDURE FOR DRYING EFFICACY
STUDY IN FLUIDIZED BED DRYER:
Ensure the cleaning of machine
Load the wet mass in the FBD product container
Set the process time & outlet temperature and run
the FBD.
After completion of drying take out FBD bowl and
collect the sample
At least 2.0 gm of sample is sampled for % MC
check from the top, middle and bottom trays and
will be reported
26
Conti…
Sampling Procedure:
