What is Specification Limit?
Specification Limit
The width that separates pass and fail.
What it means
Specification limits are the ranges within which a value must be contained for the product to be usable. It comes from customer needs or design. If it deviates, it is defective.
In general, it is a good process when the control limits are well within the specification limits.
At the pen factory
If the refill line thickness is 0.45~0.55mm, it is acceptable. This is the specification limit.
Why it matters
The criteria for passing must be set in numbers so that the same decision can be made about who is a successful candidate.
