Objective

The objective of this Operational Qualification (OQ) protocol is to verify that the Hammer Mill operates within specified parameters and meets the requirements outlined in the User Requirement Specification (URS).

Scope

This OQ protocol applies to the Hammer Mill used in the production of solid dosage forms (OSD) within the production/milling area. It covers the size reduction process, ensuring direct product impact is evaluated and validated.

Responsibilities

The following personnel are responsible for the execution and approval of this OQ protocol:

  • Validation Team: Execute and document tests
  • Quality Assurance: Review and approve documentation
  • Production Team: Provide operational support

Prerequisites

  • Installation Qualification (IQ) must be completed and approved.
  • All necessary documentation must be available for review.
  • Training on equipment operation must be completed by operators.

Equipment Description

The Hammer Mill is a size reduction machine used to produce a uniform particle size for solid dosage forms. Key features include adjustable speed settings, various screen sizes for output particle size distribution (PSD), and heat monitoring capabilities.

Test Plan

Test ID Procedure Acceptance Criteria Evidence
OQ-01 Verify speed settings at specified RPM. Speed within ±10% of target RPM. Calibration report, logbook.
OQ-02 Measure screen output for PSD. PSD meets specifications per URS. PSD analysis report.
OQ-03 Monitor heat generation during operation. Heat remains within acceptable limits. Temperature log, incident report.

Detailed Test Cases

Test Case OQ-01: Speed Verification

Procedure: Set the Hammer Mill to the target RPM and verify the actual speed using a calibrated tachometer.

Acceptance Criteria: Speed must be within ±10% of the target RPM as specified in the URS.

Evidence: Documented calibration report and logbook entries.

Test Case OQ-02: PSD Measurement

Procedure: Collect samples at the output and analyze using appropriate sieving techniques to determine PSD.

Acceptance Criteria: PSD must conform to the specifications outlined in the URS.

Evidence: PSD analysis report detailing results.

Test Case OQ-03: Heat Monitoring

Procedure: Monitor the temperature of the Hammer Mill during operation for a specified duration.

Acceptance Criteria: Temperature must not exceed limits set in the URS.

Evidence: Temperature logs and any incident reports if limits are exceeded.

Deviations

Any deviations from the acceptance criteria must be documented and investigated. A root cause analysis should be performed, and corrective actions must be implemented to prevent recurrence.

Approvals

All test results must be reviewed and approved by the Quality Assurance team before the equipment can be deemed qualified for use in production.
