Salt Spray Test Chamber is known with multiple names in the market such as salt fog chamber, corrosion test chamber, salt spray fog test chamber, corrosion chambers, environmental test chambers and many more. The testing chambers are widely used in different production verticals to test the corrosion resistance strength of the layered components, electronic parts, metal products and plated products, etc. You can find many models in the market but to make the right purchase always make sure that the machine is designed keeping in mind various test standards such as ISO9227, ASTM-B117, and many more. Continuing the discussion, in this blog we will discuss the technical specifications of Salt Spray Chambers, its working process and applications. Let’s explore.

Technical Specifications of Corrosion Test Chambers

• The testing machine is designed with a waterproof structure. The waterproof strength is ensured with the chamber cover and the body that ensures zero salt spray overflow.
• The testing machine has a spraying system, salt solution reservoir tank and nozzle. All this equipment in the machine ensures even salt spray distribution and free settlement of fog.
• The testing chamber can easily maintain the temperature between 5? to 50?. The temperature value cannot be less than the current temperature. The temperature of the saturated barrel can be set between +40°C to +63°C with the temperature fluctuation rate of ≤ ±1°C
• The Salt Spray Test time can be set between 0-99, 999m which is completely adjustable
• The salt spray test chamber can be used to perform multiple types of tests ie. Neutral test, AASS test, Copper acceleration or CASS test, customized test, programmable test, and more. Each test needs either continuous or intermittent spray as per the industry standards for the particular application.
• The testing chamber comes with the sample holder provision where you can set the angle of the sample between 15 to 30 degrees
• How to Perform a Salt Spray Test Using a Corrosion Test Chamber?
• Place the samples on the sample holder as mentioned in the standards.
• Set the temperature of the air saturator considering the table given in the standard
• Make sure the samples are placed at a distance so that droplets from one sample will not fall on to the other sample.
• Place an empty collection vessel inside the chamber. Try to keep it at a height of the sample for the precise results.
• Make sure that the room temperature, temperature of air saturator and atomizer are within the standard limits.
• Spray with the atomized solution at a neutral temperature of the chamber. Refer to the standards to check the chamber temperature as it will vary as per the test requirements.
• Double-check that the collected solution is within the acceptable range.
• Make sure that the saline solution in the tank should be less than 5.0% or +/- 1.0% NaCl
• Take a note of the pH of the saline solution and ensure that it is in the standard limits.
• Carefully monitor the level of saline in the tank and ensure that there is sufficient saline for the next 24 - 48 hours to conduct the test without any interruptions.
