ISO 9277 Corrosion Testing of Artificial Atmospheres

ISO 9277 compliance testing determines overall specific external and internal surface area according to the Brunauer, Emmett and Teller (BET) method. As a certified environmental lab, we realize the importance of ISO 9277 artificial atmosphere testing. Meeting the environmental ISO corrosion testing requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone provides the peace of mind that all of your needs will be met. Our pricing is competitive and we offer volume discounts. When products do not meet the requirements, we assist with finding solutions.

Summary of ISO 9277 Artificial Atmosphere Corrosion Testing

The ISO 9277 BET method is applicable only to adsorption isotherms of type II and type IV. Inaccessible pores are not detected. The BET method cannot reliably be applied to solids which absorb the measuring gas.

Specific surface area is a crucial parameter for optimizing the use of mesoporous and macroporous materials. Additionally, it also optimizes microporous materials in many applications. However, due to the complex nature of porous materials, no single experimental technique can be expected to provide an evaluation of the “absolute” surface area. 

Despite the well-known limitations, the Brunauer, Emmett and Teller (BET) method continues to be widely used for the evaluation of specific surface areas of porous materials. Therefore, the specific surface area obtained by applying the BET method on adsorption isotherms from microporous solids does not reflect the true internal surface area. It is considered as a kind of characteristic or equivalent BET area.
