Salt spray chamber simulates the harsh environmental condition or standardized artificial corrosion conditions which accelerates corrosion on the metallic materials. To create such harsh condition inside this salt spray tester the chamber manufactured should withstand these globally accepted standards to achieve high quality specimen. The results obtained by using salt spray chamber test will let you know the suitability and usability of that particular material in various industrial sectors like aerospace, automobile, energy, marine, defense and many more.
Let’s go through all the standards one by one and understand why its implementation plays a great role in the reliability, longevity and quality of the material. Pacorr salt spray chamber strictly follows the ASTM B117, ISO 2997 and JIS Z 2371.
ASTM B117
It provides the basic standard scope to follow the objectivity and procedure of applications properly. Primarily it is applicable for the process of standardized corrosion resistant environment for metallic materials. Meticulous detailing of apparatus is needed to maintain fog, temperature and saline water concentration. The guidance for handling the test specimen from various industries like automobile, aerospace, agriculture, energy sector to get the repeatable observations consistently. Though the laboratories might vary while conducting salt spray chamber testing but its test conditions should always specified whether it’s related to consistency, temperature, exposure duration and test condition control.
Guidance is provided that how the experiment will be conducted throughout the time period stepwise from the setting of temperature, creating air pressure through gauge upto regulating the saline water and maintaining consistent required fog condition inside the fibre reinforced body. The standardised reporting should be maintained like test conditions such as required temperature should be upto 45 degree celcius and maintaining 1 to 2 ml/hr water must be collected in fog collector and if it is not happening it means need to adjust the water flow or air flow to maintain it. Reproducibility and repetitiveness is consistently maintained. Standardised test service conditions for assessing real condition natural environment for corrosion is nurtured.
ASTM B117 provides a comprehensive framework for conducting salt spray testing and evaluating the corrosion resistance of materials in a standardized and internationally accepted manner.
ISO 9227
International standard organization (ISO) 9227 is a international community which provides standardised and specific procedure, outlines for design, construction, and operation, test conditions, test duration, specimen preparation, and the observed corrosion characteristics. It sets the standard criteria for the evaluation of salt spray chamber test to perform consistent methods, observing the behavior of material to understand the suitability of application to various industries. ISO 9227 enumerates various methods Copper-accelerated acetic acid-salt fog (CASS) tests, acetic acid-salt fog (AASS) and neutral salt spray test(NSS).
JIS Z 2371
JIS Z 2371 stands for Japanese Industrial Standards. JIS Z 2371 serves as a crucial reference in Japan for evaluating the corrosion resistance of metals. It provides a comprehensive framework for conducting salt spray tests, simulating corrosive conditions. This standard guides users through the entire testing process, from setting up the test to preparing materials and interpreting results. Essentially, it's the standardized preferred manual in Japan to determine how well metals and coatings can withstand environmental challenges. Industries in Japan rely on JIS Z 2371 to meet local standards and regulations, ensuring the durability and reliability of materials in the face of corrosion.
All these standards ASTM B117,ISO 9227 and JIS Z 2371 share similarities in testing objectives, apparatus, and procedures, the distinctions stem from regional preferences, specific industrial requirements, and the governing bodies behind each standard. Manufacturer should select the appropriate standard based on their geographical location, industry specifications, and adherence to regulatory standards. This ensures that the chosen testing standard is in line with the specific context and conditions relevant to the user's location and industry, facilitating accurate and meaningful assessments of corrosion resistance for metallic materials for salt spray tests.
How these standards are beneficial?
The standards ASTM B117, ISO 9227, and JIS Z 2371 play a crucial role in supporting manufacturers in the domain of salt spray testing. Firstly, these standards provide manufacturers with universally accepted guidelines, ensuring consistency and reliability in the evaluation of corrosion resistance for metallic materials. This consistency is crucial for manufacturers, enabling them to generate reliable and comparable results, establishing a common frame work for testing procedures. Secondly, adherence to these standards assists manufacturers in meeting regulatory requirements, both domestically and internationally, ensuring their products align with industry norms. Thirdly, the standards contribute to the overall enhancement of product quality by encouraging innovation and research and development in corrosion-resistant materials. Ultimately, the incorporation of these standards in salt spray testing empowers manufacturers to create durable and high-quality materials, strengthening their competitive position in the global market.
Pacorr testing instruments strongly incorporates all these standards while manufacturing and designing salt spray test chambers understanding the universal industry norms.
