The Simple Decision Rule is applied in reports other than OSH measurements. Measurement uncertainty is given in OSH measurements. In reports with the TÜRKAK logo, an opinion is obtained on whether the customer requests a Declaration of Conformity.
If the legislation, product or test standard requires a declaration of conformity in the laboratory report, but there is no information on the effects of the confidence level and measurement uncertainty in the assessment of conformity in the relevant standards or legislation, the laboratory evaluates the test result obtained only as being within the specified limits, whether it is suitable or not, without considering the confidence level and measurement uncertainty.
In cases where the competent authority requests the application of the decision rule for results to be declared conformity in test/measurement works carried out within the scope of environmental legislation, the measurement uncertainty is added to the measurement value in the relevant report and the report is revised and submitted to the competent authority.
