This document outlines various quality control tests performed on pharmaceutical packaging and containers. It discusses QC tests for containers made of glass, plastic, and metal to test for chemical resistance, leakage, pressure resistance, and other properties. It also summarizes QC tests for closures like sterility testing, fragmentation testing, and pH testing of aqueous extracts. Finally, common QC tests for secondary packaging materials like paper and board are mentioned, including moisture content, strength, and barrier property testing. The document provides detailed methods and acceptance criteria for many important packaging quality control tests.

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.
Step 1

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 121C̊ 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

13. 6. Thermal Shock Test
Step 1
• Place sample container in upright position in tray &
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
C̊ temp. difference should be there.)
Step 3
• The amount of thermal shock a bottle can
withstand is based on construction.
