What is not a requirement for tool substitution according to SPMIG?

In the context of the Navy’s Standardized Procedures for Maintenance and Inspection Guidance (SPMIG), the requirements for tool substitution emphasize that any replacement tool must effectively meet the operational needs of the task. This ensures that it can perform correctly and safely in place of the original tool.

Meeting basic requirements for form, fit, and function is essential because it ensures that the substitute tool can physically and operationally replace the original tool without compromising the task's integrity. Completing necessary inspections guarantees that the tool is in suitable condition for use, reflecting best practices for safety and reliability. Following manufacturer guidelines ensures that the tool operates as intended and adheres to established safety and performance standards.

The assertion that a tool must be maintenance-free is not a requirement for tool substitution. Tools may require some level of maintenance regardless of their designation as substitutes, as their reliability depends on regular care and upkeep to function effectively. Therefore, the emphasis is on whether they fulfill the requirements in practice rather than the absence of maintenance needs.
