Objective

The objective of this Performance Qualification (PQ) protocol is to verify that the Solvent Storage Tank operates within specified limits and meets the requirements outlined in the User Requirement Specification (URS), Annex 11, and Annex 15.

Scope

This protocol applies to the Solvent Storage Tank (SS / GL) used in the production area for the storage of solvents in API manufacturing. The PQ will cover critical parameters related to the equipment’s operation.

Responsibilities

The Validation Team is responsible for the execution of this PQ protocol, ensuring compliance with regulatory requirements and internal standards.

Prerequisites

  • Completion of Installation Qualification (IQ) and Operational Qualification (OQ).
  • Availability of all necessary equipment and materials.
  • Training of personnel involved in the PQ activities.

Equipment Description

The Solvent Storage Tank is designed to store solvents used in chemical synthesis and purification processes. It features a PLC-controlled system for monitoring and controlling critical parameters including level, temperature, and pressure.

Test Plan

Test ID Procedure Acceptance Criteria Evidence
PQ-01 Verify level measurement accuracy Level readings within ±5% of the actual level Calibration certificate, logbook entries
PQ-02 Verify temperature control Temperature maintained within specified range Temperature logs, PLC audit trail
PQ-03 Verify pressure control Pressure maintained within specified range Pressure logs, PLC audit trail

Detailed Test Cases

Test Case PQ-01: Verify Level Measurement Accuracy

Procedure: Measure the solvent level using the tank’s level indicator and compare it with a calibrated measuring device.

Acceptance Criteria: Level readings must be within ±5% of the actual level.

Evidence: Documented results, calibration certificate.

Test Case PQ-02: Verify Temperature Control

Procedure: Monitor the temperature of the solvent in the tank over a defined period.

Acceptance Criteria: Temperature must be maintained within the specified range.

Evidence: Temperature logs, PLC audit trail logs.

Test Case PQ-03: Verify Pressure Control

Procedure: Monitor the pressure within the tank during operation.

Acceptance Criteria: Pressure must be maintained within the specified range.

Evidence: Pressure logs, PLC audit trail logs.

Deviations

Any deviations from the acceptance criteria must be documented, including the reason for the deviation and the corrective actions taken.
