Anonymous January 19, 2022

OBJECTIVE

To lay down a procedure for the operation of the Hardness tester.

SCOPE

This procedure applies to the pharmaceutical manufacturing facilities of XYZ Limited.

RESPONSIBILITY

The Quality Control Chemist is responsible for the implementation of the process.

The Quality Control Manager is responsible for the execution of the procedure.

PROCEDURE

Select 10 tablets at random for hardness testing from the sampled lot.
Place one tablet on its edge and hold it firmly in position. If the tablet has a break-line, then the break-line should be horizontal. Adjust the scale so that the zero on the scale coincides with the pointer.
Turn the screw at the top of the tester slowly to create pressure on the plunger. Continue turning the screw slowly until the tablet breaks. Record the observed reading.

Repeat the above steps for nine other tablets. Determine the average hardness.
Check the Product Specifications for compliance.
Note: If average hardness is not within the product specification range, immediately inform the department in charge for appropriate action.
