CASS Cum Salt Spray Chamber
The CASS Cum Salt Spray Test Chamber is precision testing equipment that can evaluate the performance of painted, plated, or coated surfaces under aggressive corrosion conditions. The term CASS here refers to the highly advanced Copper Accelerated Acetic Acid Salt Spray test, which is far more advanced than the conventional neutral salt spray test.
While the common salt spray chamber uses a sodium chloride mist for spraying, the CASS Cum Salt Spray Test Chamber involves a solution consisting of copper chloride and acetic acid. Thus, a very harsh environment is formed in the test chamber, which mimics years of real-life corrosive environment conditions in a few hours. CASS is the most reliable test for decorative chrome plating and anodised aluminium.
Effective Lab India’s CASS Cum Salt Spray Test Chambers provide reliable and standard results that make us the best salt spray chamber manufacturers in India.
Where Durability Meets Precision
Ensuring each product is crafted to withstand the toughest conditions with unmatched accuracy
Why Is the CASS Test Critical for Your Industry?
Corrosion is one of the costliest types of product failure. When a product part corrodes due to poor surface protection, it may result in product recall, potential dangers, and costly expenses. In order to prevent this issue, the CASS test process applies an accelerated corrosion test on a product even before its production.
ISO 9227, ASTM B368, and DIN 50021 are some of the international standards requiring the CASS Cum Salt Spray Test Chamber. Any manufacturing industry that adheres to this standard, as well as other quality management systems needing evidence of corrosion resistance, will need this chamber to continue their business operations.
Key Industries That Rely on CASS Testing:
• Automobiles: Checking chrome bumper coating, chrome wheel rim coating, chrome door handles, and body coatings
• Aviation: Corrosion testing of fasteners, brackets, and structural parts
- Electronic Assemblies: Coating testing of printed circuit boards, connectors, and metal enclosures
- Shipbuilding and Defense: Seawater corrosion testing of hardware components
Supplier to Paints & Coatings Manufacturers: Primer and top coat performance testing, as well as galvanized parts testing - Constructions: Testing of nuts, bolts, hinges, and locks

How Does a CASS Cum Salt Spray Test Chamber Work?
Operating Principle of the CASS Cum Salt Spray Test Chamber: The principle of operation of the CASS Cum Salt Spray Test Chamber is the atomisation of a specifically mixed corrosive solution into the specially designed chamber.
Below is a procedure of the steps involved in the conduct of such a test:
- Test Solution Preparation: The solution mixture includes 50 g/L sodium chloride, 0.26 g/L copper chloride, and glacial acetic acid to get a pH range of 3.1-3.3.
- Sample Placements: The samples are placed at specific angles in the specimen racks.
- Specimen Rack Preparation: The operator programs the temperature, test time, air pressure, and spray cycle parameters using the HMI touchscreen.
- Fog Formation: The compressed air is sprayed through the atomiser to form the salt fog.
- Test Control: The PID controller keeps the test chamber at constant temperature. Data logs and graphing functions monitor the test process.
- Air Purging Post-Test: An automatic air purge system eliminates any residues after test completion.
- Results Interpretation: Inspection and analysis of the specimens for any signs of corrosion, blistering, adhesion loss, among others.

Frequently Asked Questions (FAQs)
Question: What does the abbreviation CASS mean, and why is it different from a regular salt spray test?
Answer: CASS means Copper Accelerated Acetic Acid Salt Spray. As opposed to a regular NSS test where the testing medium is sodium chloride at 35°C, in a CASS test, the solution is made of copper chloride and acetic acid at a temperature of 49°C. The combination of the substances in the solution and the temperature makes it far more corrosive, giving the tester an ability to evaluate the environmental degradation of materials on a fast track.
Question: Which model of the CASS Cum Salt Spray Chamber should I opt for in terms of choosing the most suitable one for my test requirements?
Answer: The selection of an appropriate model will depend on the dimensions and volume of the specimens used in your testing process. Effective Lab India manufactures four different models, namely CASS-250, CASS-300, CASS-450, and CASS-1000, having capacities of 250 liters up to 1000 liters within their internal chambers. If you require a chamber for small components like fasteners and connectors, then the best choices would be CASS-250 or CASS-300. On the other hand, if you are working with large assemblies, the CASS-1000 would be sufficient.
Question: Is there an after-sales support facility for the salt spray chamber offered by Effective Lab India?
Answer: Yes. Effective Lab India ensures that after-sales service is available, which encompasses installation at site, training of operators, preventive maintenance, and calibration. Our engineering service personnel have been trained to undertake servicing and calibration of all models in the range, and we can assist you with annual calibration to maintain the integrity of your tests.

Know About Our Products
The CASS Cum Salt Spray Chamber is an advanced testing device used to evaluate the corrosion resistance of materials under simulated harsh environmental conditions. In this FAQ, we address common questions regarding its operation, maintenance, and applications. Learn how the chamber replicates atmospheric conditions, ensures product durability, and meets industry standards.
The main difference between a Salt Spray Test and a Cass test is their testing method. In a salt spray test, a mist of salt water is sprayed on the sample and a Cass test involves a cyclic exposure to a salt spray which is followed by a controlled humidity environment.
The full form of a Cass test is Copper Accelerated Acetic Acid Salt Spray (CASS).
Both Cass and Salt spray test has their own purposes and advantages. However, the salt spray test is a common and simpler method while the Cass Cum test is an advanced and more comprehensive test that incorporates humidity and dry cycles for the simulation of several environmental conditions. However, the choice depends on the specific testing scenario.
