Which of the following qualifications is required for inspection personnel?

The requirement for inspection personnel includes having a working knowledge of related standards and specifications. This qualification is vital because inspection personnel need to understand the criteria and regulations that govern the installation and performance of refractory materials. Familiarity with relevant standards ensures that they can accurately evaluate the quality and compliance of the materials and processes used in refractory applications.

Having this knowledge allows inspection personnel to identify any deficiencies or issues during the installation process, ensuring that all work meets safety and performance standards. It equips them to make informed decisions about materials' suitability and adherence to industry norms, ultimately contributing to the longevity and effectiveness of refractory systems.

While commercial affiliations with contractors, qualifications as an engineer, and a lack of prior experience might relate to certain aspects of the industry, they do not directly address the critical need for inspectors to possess a solid understanding of the standards and specifications that govern their work. Therefore, having a working knowledge of these standards is the essential qualification for inspecting personnel in the refractory field.
