Aerosol Can Inspection Service for Global Packaging Safety and Compliance
As an ISO/IEC 17025 accredited laboratory, we provide a specialized aerosol can inspection service that verifies pressure integrity, material quality, dimensional accuracy, leakage resistance, and safety valve functionality of aerosol containers used in personal care, household, industrial, and pharmaceutical products. Our aerosol can inspection service supports manufacturers and exporters who must demonstrate conformity to FEA 210, FEA 220, DOT 2P/2Q, EN 15006, and regional dangerous goods transport regulations across the European Union, North America, the Middle East, and Asia. Every test is performed under our CNAS-accredited quality system, producing reports accepted by notified bodies, customs authorities, and procurement teams worldwide.
Product Samples We Regularly Test in Our Aerosol Can Inspection Service
- Tinplate and aluminum aerosol cans — for cosmetic sprays, household cleaners, paints, and industrial lubricants
- Three-piece and two-piece aerosol containers — with welded or drawn construction and various dome and base configurations
- Internal lacquered and coated aerosol cans — for water-based formulations, food products, and aggressive chemical contents
- Plastic and composite aerosol cans — for specialty packaging requiring corrosion resistance or unique aesthetics
- Aerosol valves and actuators — including metered dose valves, continuous spray valves, and bag-on-valve systems
- Complete aerosol packaging systems — filled cans with propellant, product, and integrated dispensing hardware
Aerosol Can Inspection Service for Pressure and Leak Integrity
- Hydrostatic pressure test per FEA 210 and DOT 2P — the empty aerosol can is filled with water and pressurized to a defined multiple of the rated pressure to verify the shell, seams, and valve mounting withstand the design pressure without leakage, deformation, or rupture.
- Burst pressure and ultimate strength verification per FEA 220 — the can is pressurized hydraulically until rupture to determine the ultimate safety margin, which must exceed a specified factor above the maximum allowable working pressure for the propellant system.
- Leak tightness test by water bath and bubble emission per FEA 210 and internal protocols — the filled aerosol can is immersed in a heated water bath and observed for continuous bubble streams, detecting leaks at the valve crimp, side seam, or bottom double seam.
- Pressure decay and mass loss measurement per ASTM E2930 — the filled can is stored under controlled conditions and the internal pressure and weight are monitored over time to detect slow leakage of propellant or product through the valve or seams.
- Valve crimp integrity and pull-off force per FEA 210 — the force required to detach the valve from the aerosol can is measured, ensuring the crimped connection remains secure under internal pressure and mechanical handling.
- Seam tightness and double seam evaluation per FEA 220 — the bottom and top double seams are sectioned and measured for body hook, cover hook, overlap, and tightness, verifying the seam construction provides a hermetic seal.
Aerosol Can Inspection Service for Mechanical and Dimensional Accuracy
- Can diameter, height, and wall thickness measurement per ISO 2768 and customer drawings — laser micrometers and coordinate measuring machines verify all critical dimensions, ensuring the aerosol can fits correctly into filling lines, capping machines, and actuator assemblies.
- Double seam and bead geometry verification per FEA 210 — the seam and expansion bead profiles are inspected with optical comparators and sectioned samples to confirm they meet the specified dimensions for pressure resistance and stackability.
- Surface roughness and coating uniformity per ISO 4287 and ISO 2178 — the internal lacquer thickness and the external print or coating are measured to verify the specified protection and appearance.
- Eccentricity and roundness measurement per ISO 1101 — the aerosol can body is checked for roundness and concentricity to prevent deformation during filling and to ensure proper valve seating.
- Visual defect inspection under D65 illumination — systematic examination for dents, scratches, print defects, and contamination against agreed acceptance criteria and master reference samples.
Aerosol Can Inspection Service for Material and Corrosion Resistance
- Tinplate and aluminum alloy verification by optical emission spectrometry per ASTM E415 — the base metal composition is confirmed to verify the specified grade and to detect material substitution.
- Internal lacquer adhesion and porosity per ASTM D3359 and internal electrochemical methods — the protective lacquer is tested for adhesion and pinhole-free coverage, ensuring the product does not react with the metal can.
- Neutral salt spray and cyclic corrosion testing per ISO 9227 and ASTM B117 — the aerosol can and its seams are exposed to salt fog to evaluate rust formation, coating degradation, and seam integrity in marine and humid environments.
- Resistance to product formulation and propellant chemicals per ASTM D543 and ISO 175 — the internal lacquer and valve elastomers are immersed in the intended formulation to verify no softening, swelling, or degradation occurs over the product shelf life.
- Stress corrosion cracking resistance per ASTM G36 — for aluminum aerosol cans, the material is tested to ensure it does not crack under the combined effects of internal pressure and aggressive product chemistry.
Report Recognition and ISO/IEC 17025 Compliance
All test methods described in this aerosol can inspection service are covered by our ISO/IEC 17025 scope of accreditation. Our technical reports are accepted by European notified bodies for pressure equipment and dangerous goods packaging, by North American DOT and FDA regulators, and by customs and procurement authorities across the Middle East, Australia, and Asia. Whether you require a complete qualification dossier for a new aerosol can design, a batch release inspection for an export shipment, or a root cause failure analysis of a leakage or corrosion issue, our laboratory provides the measurement accuracy and packaging safety expertise that the global aerosol industry demands.
