General requirement
Automatic, mechanical, or electronic equipment
or other types of equipment, including
computers, or related systems that will perform
a function satisfactorily, may be used in the
manufacture, processing, packing, and holding
of a drug product. If such equipment is so used,
it shall be routinely calibrated, inspected, or
checked according to a written program
designed to assure proper performance.
Written records of those calibration checks and
inspections shall be maintained.

Laboratory controls include:
The calibration of instruments, apparatus,
gauges, and recording devices at suitable
intervals in accordance with an established
written program containing specific
directions, schedules, limits for accuracy and
precision, and provisions for remedial action
in the event accuracy and/or precision limits
are not met. Instruments, apparatus,
gauges, and recording devices not meeting
established specifications shall not be used.

Unless otherwise specified, when
substances must be “accurately weighed”,
the weighing shall be performed using a
balance calibrated over the operating range
and meets the requirements defined for
repeatability and accuracy.
Balance – accurately weigh
USP 36 <41>
Repeatability is satisfactory if two times
the standard deviation of the weighed
value, divided by the nominal value of
the weight used, does not exceed 0.10%
2 x SDW/W ≤ 0.0010
© 2014 The Lanese Group, Inc. 53
USP 36 <41>
© 2013 The Lanese Group, Inc. 54
Weigh one test weight no less than 10
times. Must be within the balance range
Need not be calibrated
Repeatability = standard deviation.
Repeatability is independent of mass.
Repeatability
USP – 36 <41>
If
• The weight = 100 mg
• The standard deviation of 12 weighings = 0.05 mg
2 x 0.05mg./100mg. = 0.001 = 0.1%
© 2014 The Lanese Group, Inc. 55
If the standard deviation is less than
0.41d, where d is the scale interval,
replace the standard deviation with
0.41d.
© 2014 The Lanese Group, Inc. 56 USP 36 <41>
© 2013 The Lanese Group, Inc. 57
Accuracy of a balance is satisfactory if its weighing
value, when tested with a suitable weight(s) is
within 0.10% of the testing value.
A test weight is suitable if it has a mass between
5% and 100% of the balance’s capacity.
A test weight’s maximum permissible error (mpe)
(calibration uncertainty) shall be NMT one-third of the
applied test limit of the accuracy test.

Test Accuracy Ratio
• TAR
• Test Uncertainty Ratio (TUR)
• Most programs require at least 4:1
• Process calibration tolerance should be less
than 1/4th process tolerance
