Compliance with specified limits

The statement of compliance is based on a 95 % probability for the expanded uncertainty and is only valid for the tested item.

The decision is based on the measured value for the specific parameter.

PThe test object is determined to fulfil the requirement.
The measured value is within the specified limit, even when the measurement uncertainty is taken into account.
N+The test object is determined to fulfil the requirement.
The measured value is within the specified limit.

It is however not possible to state an absolute compliance with the requirement using a 95 % coverage probability for the expanded uncertainty. The measured value is within the specified limits by a margin less than the measurement uncertainty.
N-The test object is determined to fail to fulfil the requirement.
The measured value is outside the specified limit.

It is however not possible to state an absolute non-compliance accordance with the requirement using a 95 % coverage probability for the expanded uncertainty. The measured value is outside the specified limits by a margin less than the measurement uncertainty.
FThe test object is determined to fail to fulfil the requirement.
The measured value is outside the specified limit, even when the measurement uncertainty is taken into account.
