Equipment Calibration Procedures for MDIs
1) Purpose
The purpose of this SOP is to establish the procedures for the calibration of equipment used in the manufacturing and testing of metered-dose inhalers (MDIs) to ensure accuracy, reliability, and compliance with regulatory requirements.
2) Scope
This SOP applies to all personnel involved in the calibration of equipment used for MDIs at the manufacturing facility, including calibration technicians, laboratory personnel, and quality assurance staff.
3) Responsibilities
The responsibilities for this SOP include performing equipment calibration, maintaining calibration records, and ensuring equipment accuracy. Specific roles include:
Calibration Technicians: Perform equipment calibration as per the schedule.
Laboratory Personnel: Use calibrated equipment for testing and analysis.
Quality Assurance: Verify calibration procedures and document compliance.
4) Procedure
