What is the difference between 'class' and 'classification' in W47.1?

• A. Class is a position category; Classification refers to types of welding personnel
• B. Class refers to welding procedures; Classification refers to welding tests
• C. Class refers to certified companies; Classification refers to documents
• D. Class refers to safety protocols; Classification refers to equipment

Answer: (A)

The main idea is that W47.1 uses two different terms to describe different aspects of personnel in the welding program. A person’s class is the position category they hold—the role with its level of authority and responsibility on the job. Classification, however, refers to the type of welding personnel being talked about or certified—such as welders, inspectors, supervisors, etc.—the categories that the program recognizes for qualifications and scope of work. So, the correct concept is that class defines the job role, while classification defines the kind of personnel involved in welding activities under the program. This distinction matters because supervision, qualification, and scope of work are tied to the specific role (class) and the broader category of personnel (classification) being managed or certified. The other options mix up these ideas by linking class or classification to procedures, tests, documents, safety protocols, or equipment, which is not how W47.1 distinguishes them.
