What precautions should be taken to ensure accurate and repeatable results in salt spray testing?

Salt spray testing is one of the essential steps in quality control for the automotive and metal components industry. When metal components come in contact with a corrosive environment, then they react and manufacturers can easily determine their durability for their intended applications. With the Presto salt spray testing chamber, automotive manufacturers can accurately test their products against corrosion by simulating a salt-laden environment and in a controlled testing environment.

Presto is Asia’s No.1 manufacturer of laboratory testing instruments and has designed this high-quality testing equipment at the best and most affordable prices. This laboratory testing instrument plays an important role in determining a product’s durability.

In this blog, we will discuss brief information about the Presto salt spray testing instrument and precautions that should be taken to ensure accurate and repeatable test results in salt spray testing.

Simulate products to corrosive environments to ensure their durability

Salt spray corrosion test or ASTM B117 lab test is one of the high-quality tests that are used in the automobile industry to test the corrosion resistance of materials accurately. This quality procedure involves subjecting samples to a controlled environment where they are exposed to an intensive salt spray.

The salt spray testing will aid in identifying potential weaknesses in materials used for car parts or protective coatings by accelerating corrosion reactions under accelerated conditions.

To conduct accurate salt spray tests on the metals, manufacturers can easily make use of a Presto salt spray chamber. This chamber is useful and beneficial for the metal industry.

Presto corrosion analyzer can accurately test the products in a controlled environment to assess whether the components can stand up in the intended application or not. The Korrox IV salt spray chamber has a robust construction with a fibre-reinforced body with a triple wall structure.

This HMI-based touchscreen model comes with inbuilt temperature settings and easy data management to conduct corrosion-resistance tests on the materials with ease.

It has been designed with the latest features that make it easy for users to test their products against corrosion.

Tips to remember while conducting salt spray tests for accurate and repeatable results

Whenever you conduct salt spray tests on the materials, it is important for you to remember some useful tips for accurate and repeatable test results.

• Whenever you conduct a salt spray test using the Presto salt spray testing chamber, you need to check the communication cable thoroughly and avoid any loose connections.

• Another essential tip you must follow while operating this salt spray testing equipment is that you should check the inner chamber temperature because it should be more than an outer chamber. This will help you avoid triggering the alarm automatically.

• If you are getting inconsistent fog values, then you should check the atomizer tip. It should be kept in place and regular pressure should be monitored to get accurate test results.

Besides these tips, it is important to maintain this lab testing instrument to get accurate salt spray corrosion test results.
