What Is a Salt Spray Test Chamber?
A salt spray test chamber, also called a salt fog chamber or corrosion test chamber, creates a controlled corrosive atmosphere to compare the corrosion resistance of metallic materials, protective coatings, plated parts and surface-treated products. It is widely used in quality control, product development and comparative corrosion testing. For related environmental testing, you can also explore our Humidity Temperature Test Chamber.
Salt Spray Test Standards: ASTM B117 and ISO 9227
ASTM B117 is the standard practice for operating salt spray (fog) apparatus. It defines the apparatus, procedure and conditions required to create and maintain a controlled salt spray environment. ASTM also notes that the practice itself does not prescribe the exposure period for a specific product or how results should be interpreted.
ISO 9227 specifies apparatus, reagents and procedures for Neutral Salt Spray (NSS), Acetic Acid Salt Spray (AASS) and Copper-Accelerated Acetic Acid Salt Spray (CASS) tests. The applicable product or customer specification should determine the required exposure duration and acceptance criteria.
How Does a Salt Spray Test Chamber Work?
A prepared salt solution is atomized through a corrosion-resistant nozzle to create a fine fog inside the test chamber. Specimens are exposed under controlled chamber temperature, air pressure, solution chemistry and fog collection conditions according to the selected test method. After the specified exposure period, the specimens are evaluated using the acceptance criteria defined by the applicable product specification or test plan.
Types of Salt Spray and Corrosion Tests
Neutral Salt Spray Test (NSS)
NSS uses a neutral salt solution and is one of the most common methods for comparative corrosion testing of metallic materials and protective coatings.
Acetic Acid Salt Spray Test (AASS)
AASS uses an acidified salt solution for applications where the applicable standard or product specification requires acidic salt-fog exposure.
Copper-Accelerated Acetic Acid Salt Spray Test (CASS)
CASS uses a copper-accelerated acidic salt solution and is applied where a more aggressive corrosion environment is specified for suitable coated or plated materials.
Cyclic Corrosion Testing (CCT)
Cyclic corrosion testing alternates environmental stages such as salt spray, humidity and drying according to a programmed test cycle. For humidity-based environmental testing, see our Refrigerated Humidity Chamber. Confirm the exact cycle, temperature range and optional hardware required for your intended CCT method before ordering.
How to Choose a Salt Spray Test Chamber
The right chamber should be selected from the test requirement first, not only from price or nominal capacity. Before requesting a model, confirm the applicable standard, test method, specimen dimensions, number of samples per batch, exposure duration, chamber construction, control system and site utilities.
| Selection Factor | What to Confirm Before Ordering |
|---|---|
| Test Method | NSS, AASS, CASS or required cyclic corrosion sequence |
| Specimen Size & Quantity | Maximum specimen dimensions, rack arrangement and samples per batch |
| Chamber Capacity | 108 L, 270 L, 480 L, 980 L or customized capacity |

Salt Spray Test Chamber Construction & Control
Capacity: Standard models are available in 108 litres, 270 litres, 480 litres and 980 litres. Higher or customized capacities can be considered according to the application and specimen requirements.
Chamber Construction: Double-walled corrosion-resistant FRP construction is used to protect the chamber from the corrosive test environment. The chamber is insulated with high-density ceramic wool.
Control: Standard configurations use PID control for chamber and humidifier functions. Optional PLC-based control with a graphical touch-screen interface is available where required.
Lid: FRP/acrylic lid construction with a viewing window allows observation of specimens without unnecessarily disturbing the test. Pneumatic operation is provided according to the selected configuration.
Spray System: A corrosion-resistant glass nozzle and non-metallic atomizer generate the salt fog. Optional flow-control components are available for applications requiring additional control of solution delivery.
Solution System: A corrosion-resistant solution storage arrangement is provided for the salt solution. Exact configuration depends on chamber capacity and selected options.
Salt Spray Test Procedure: General Workflow
- Confirm the applicable standard or customer test specification.
- Prepare the required test solution and verify the relevant chemistry parameters.
- Arrange specimens so that they do not interfere with fog exposure or one another.
- Set chamber temperature, air pressure, spray/fog parameters and test duration according to the selected method.
- Run the exposure while monitoring the chamber conditions required by the test plan.
- At the end of exposure, evaluate the specimens using the acceptance criteria defined by the applicable product specification.
Important: ASTM B117 and ISO 9227 define salt-spray test environments and procedures, but the appropriate exposure time and pass/fail criteria should come from the relevant product, material, customer or industry specification.

Frequently Asked Questions About Salt Spray Test Chambers
What is a salt spray test chamber used for?
A salt spray test chamber creates a controlled salt-fog environment for comparative corrosion testing of metals, coatings, plated parts and surface-treated products. It is commonly used in quality control, product development and corrosion-resistance evaluation.
Which test methods can this chamber support?
Depending on the selected configuration, Bionics Scientific chambers can be specified for Neutral Salt Spray (NSS), Acetic Acid Salt Spray (AASS), Copper-Accelerated Acetic Acid Salt Spray (CASS) and cyclic corrosion testing requirements. Confirm the exact test method and cycle before ordering.
What is the difference between ASTM B117 and ISO 9227?
ASTM B117 describes the apparatus, procedure and conditions for operating a salt spray (fog) environment. ISO 9227 specifies methods including NSS, AASS and CASS. Neither standard by itself determines the correct exposure duration or pass/fail criteria for every product; those should be taken from the applicable product or customer specification.
What chamber capacities are available?
Standard Bionics Scientific models are available in 108 L, 270 L, 480 L and 980 L capacities. Customized capacities can be discussed when specimen dimensions or batch size require a different chamber volume.
How do I choose the correct salt spray chamber size?
Choose capacity according to the maximum specimen dimensions, number of samples per batch, required rack arrangement and applicable test method. Share these details with the quotation request so the chamber size can be matched to the intended workload.
What information should I send for a quotation?
Share the test standard, test method, specimen dimensions, number of specimens, preferred chamber capacity, control system requirement, optional accessories, electrical supply, delivery location and any calibration or documentation requirements.
Does the salt spray test predict exact outdoor service life?
No. Salt spray testing provides controlled comparative corrosion-resistance information. ASTM B117 cautions that direct prediction or extrapolation to natural-environment performance is not always reliable without appropriate supporting long-term exposure data.
Are PLC and touch-screen controls available?
Yes, PLC-based control with a graphical touch-screen interface is listed as an optional configuration. Standard configurations use PID control. Confirm the required automation and data-recording functions before ordering.
Are installation and calibration services available?
Installation, commissioning, operator training, calibration, preventive maintenance and AMC support can be discussed as part of the project scope. Availability should be confirmed for the installation location at the quotation stage.
