Upon completion of Shock and Vibration tests, the torque must be within what percentage of the manufacturer's recommended tightening torque?

The correct response is based on industry guidelines that establish requirements for maintaining mechanical integrity in electrical connections after subjecting them to conditions such as shock and vibration. When tests are completed, it is crucial that the torque applied to fasteners is within a specific range of the manufacturer's recommended tightening torque to ensure safety and reliability.

A tolerance of 10% is commonly accepted as a standard for many applications. This percentage allows for slight variations in torque that might occur due to the stresses and strains experienced during shock and vibration testing. If the torque is maintained within this range, it indicates that the connections are properly secured and less likely to fail under operational stresses, thereby preserving the functionality and safety of the system.

Options that suggest a greater deviation, such as 15% or 20%, could compromise the integrity of the connection, leading to potential failures. A more stringent tolerance, such as 5%, could be too tight for practical adjustments following testing, particularly in field applications where conditions can vary. Therefore, 10% is a balanced and practical standard for ensuring that fasteners remain within a safe operational range after such rigorous testing.
