Standard Operating Procedure for Leak Testing of Gel Tubes and Containers
1) Purpose
The purpose of this SOP is to establish procedures for performing leak testing on gel tubes and containers to ensure product integrity, safety, and compliance with regulatory requirements.
2) Scope
This SOP applies to the Production and Quality Control (QC) departments responsible for conducting leak testing on gel tubes and containers manufactured at the pharmaceutical manufacturing facility.
3) Responsibilities
Production: Perform leak testing on gel tubes and containers during the manufacturing process to prevent packaging defects.
Quality Control (QC): Conduct routine inspection and testing of gel tubes and containers to verify leak-tightness and adherence to specifications.
Quality Assurance (QA): Oversee the implementation of leak testing procedures and ensure compliance with SOPs and regulatory guidelines.
4) Procedure
4.1 Preparation
4.1.1 Gather necessary equipment for leak testing, including but not limited to vacuum chambers, immersion tanks, or automated leak detection systems.
4.1.2 Ensure calibration and validation of testing equipment according to established procedures.
4.2 Sampling
4.2.1 Select representative samples of gel tubes and containers from production batches for leak testing.
4.2.2 Document sample information, including batch/lot numbers and testing parameters.
4.3 Leak Testing Methods
4.3.1 Choose appropriate leak testing method based on container type and specifications, such as:
a) Vacuum Decay Testing
b) Immersion Testing
c) Pressure Decay Testing
d) Visual Inspection (for visible defects)
e) Automated Leak Detection Systems
4.4 Test Execution
4.4.1 Perform leak testing according to validated procedures and test parameters.
4.4.2 Record test results accurately, including any observations or deviations encountered during testing.
4.5 Acceptance Criteria
4.5.1 Define acceptance criteria for leak testing based on regulatory requirements, product specifications, and safety considerations.
4.5.2 Evaluate test results against established acceptance criteria to determine pass or fail status.
4.6 Reporting and Documentation
4.6.1 Prepare test reports documenting test methodology, results, and compliance with acceptance criteria.
4.6.2 Review and approve test reports by authorized personnel before releasing products for further processing or distribution.
4.7 Non-Conformance and Corrective Actions
4.7.1 Identify and document non-conforming products or test results.
4.7.2 Initiate corrective actions to address root causes of non-conformances and prevent recurrence.
4.8 Record Keeping and Archiving
4.8.1 Maintain detailed records of all leak testing activities, including test reports, calibration records, and corrective actions.
4.8.2 Archive records in accordance with company policies and regulatory requirements.
