5. 1. Chemical Resistant Test
a) Powdered Glass Test: It is done to estimate the
amount of alkali from powdered glass with happen at
elevated temperature. When glass is powdered,
leaching of alkali is enhanced, which can be titrated
with 0.02N sulphuric acid using methylred as an
indicator.

• Preparation of glass specimen
Step 2
• Washing the specimen

again add 15ml water and decant solution
Titrate the decant solution with 0.02N sulphuric
acid using indicator and record the volume
Limits:
7. b) Water Attack Test: This test is for Type II glass. The
principle involve in this is whether the alkali leaches from
surface of container.
Rinse thoroughly container with high purity
water. Fill it by 90% of it’s capacity with water.
Autoclave it at 121C
̊ for 30 minutes. Then it is
cooled and liquid is decanted
Decanted liquid is titrated with 0.02N Sulphuric
acid using methylred as an indicator

immersed tray in hot water for a given time.
Step 2 test.(45
• Transfer the container in cold water bath temp.
should be controlled. Examine cracks before & after
C
̊ temp. difference should be there.)
Step 3
• The amount of thermal shock a bottle can
withstand is based on construction.

15. Quality Control Test for Metal Container
• Take 50 empty tubes filled with ointment base,
sealed & kept overnight
Step 1
Step 2
• A metal bacteriological filter assembly fitted
with filter paper & heated to melting range of
ointment base.
• Base from all tubes squeezed at certain rate &
passed through filter under vaccum. further
wash with CHCL3 and observed for particles.

18. Quality Control Test for Strip and Blister packing
3/4th of water is poured in
desiccator. Strip and Blister
were placed inside
desiccators and vaccum is
applied
Later on strips, blisters
were taken out. water
present over the outer
surface were wiped out.
The content of strips and
blisters were removed
and presence of moisture
was checked
If there is no leakage,
content will not be
wetted. It indicate
perfect sealing.

This is to measure the force required to make a hypodermic
needle penetrate easily through closure.
It is measured by using piercing machine.
The piercing force must not exceed a stated value, the
hypodermic needle can get damage as a result of undesirable
hardness of closure.
