Decision:
For general insulated wiring and printed wiring boards (pwbs) that are considered critical
components, it is acceptable to identify these components in the CB Report by technical
information (e.g., electrical ratings, flame class) and reference standard only, and not include
manufacturer’s name and type number for each component.
For wiring and pwbs subjected to special requirements beyond the normal requirements applied to

investigated per 2.10.6, the specific manufacturer and type of the component should be controlled
in addition to the technical information.
