What is the maximum allowable conductivity in non-immersed areas during a conductivity test?

The maximum allowable conductivity in non-immersed areas during a conductivity test is 70 micro-seimens. This threshold is critical as it helps to ensure that the paint system's performance is not compromised by excessive electrical conductivity, which can lead to corrosion and failure of the coating system.

This maximum limit is established based on industry standards and practices to maintain the integrity and longevity of painted surfaces. Conductivity testing is essential to determine the cleanliness of the surface prior to coating application, as excess conductivity can indicate contamination or moisture presence, which can adversely affect adhesion and overall coating performance.

Regulating this parameter is vital in environments where coatings must withstand harsh conditions, making it essential that paint inspectors adhere to the specified limit of 70 micro-seimens to ensure the best outcomes for coating applications.
