1. Purpose
The purpose of this Standard Operating Procedure (SOP) is to establish a standardized approach for monitoring and ensuring the consistency of spray performance in aerosol products during batch production.
2. Scope
This SOP applies to all aerosol products manufactured in the facility and covers parameters such as spray pattern, droplet size, discharge rate, and valve performance.
3. Responsibilities
- Production Team: Responsible for conducting in-process spray consistency checks.
- Quality Control (QC) Team: Responsible for evaluating spray consistency parameters.
- Quality Assurance (QA) Team: Responsible for reviewing and approving test results.
- Engineering Team: Responsible for maintaining and calibrating spray testing equipment.
4. Accountability
The Quality Control Manager is accountable for ensuring the consistency of spray performance in all aerosol batches.
5. Procedure
5.1. Pre-Production Setup
- Ensure all spray testing equipment is calibrated before use.
- Verify that valve and actuator specifications are met.
- Record equipment status in the Spray Equipment Calibration Log (Annexure-1).
5.2. In-Process Spray Consistency Testing
- Perform spray testing on randomly selected cans from each batch.
- Evaluate key parameters:
- Spray pattern uniformity
- Droplet size distribution
- Discharge rate
- Spray duration
- Record findings in the Spray Consistency Test Log (Annexure-2).
5.3. Spray Performance Verification
- Compare results with pre-defined acceptance criteria.
- Identify
any deviations from standard performance.
Document results in the Spray Performance Report (Annexure-3).
5.4. Handling Non-Conforming Batches
- Isolate non-conforming batches for further investigation.
- Conduct root cause analysis for inconsistencies.
- Record investigations in the Non-Conformance Log (Annexure-4).
5.5. Corrective and Preventive Actions
- Implement corrective actions such as adjusting formulation or valve selection.
- Review spray testing procedures and update if necessary.
- Document actions in the Corrective Action Log (Annexure-5).
