Power Spring Torque Curve Acceptance at Multiple Turns

Quick answer: List agreed torque limits at defined turn positions, direction and test speed. A single maximum value does not characterize useful operation.

What should a torque acceptance table contain?

The return mechanism may depend on low-end torque, while user effort depends on high-end torque. Include both and any critical intermediate position. Record the assembly datum so the same measurement positions can be reproduced across batches.

A practical verification method

Retain the full trace and compare each specified position with its own limit rather than using only an average.

Use the result in an engineering request

Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
