Decision rules when declaring statements of the conformity of results
BOSMAL Automotive Research and Development Institute Ltd applies the guidance document ILAC-G8: 09/2019 (https://www.pca.gov.pl/publikacje/dokumenty/ilac/) on the use of decision rules when declaring statements of the conformity of results. Where reference documents do not indicate the decision rules, the following standard decision rules are applied:
- Binary Statement for Simple Acceptance Rule
- Binary Statement with Guard Band
- Non-binary Statement with Guard Band (conditional)
Binary Statement for Simple Acceptance Rule
The base for making the decision is the measured value without taking the guard band (introducing the lower and upper tolerance limits) and the measurement uncertainty into account. Binary statements of conformity are reported as pass/fail.
Binary Statement with Guard Band
The basis for making the decision is the measured value, taking the guard band (representing the lower and upper acceptance limits) and the measurement uncertainty into account. Binary statements of conformity are reported as pass/fail.
Non-binary Statement with Guard Band (conditional)
The basis for making the decision is the measured value, taking the guard band (representing the lower and upper acceptance limits) and the measurement uncertainty into account. Non-binary statements of conformity are reported as follows: pass / conditional pass / conditional fail / fail.
