INTRODUCTION
Compliance testing sometimes involves measured values, which lie close to the zone ofuncertainty. A different method of uncertainty evaluation by foreign authority could meanrejection of a container of goods destined for import because of expansion of the recalculated zone of uncertainty.
In the era of global marketplace it is imperative that the method for evaluating and expressinguncertainty be uniform throughout the world so that measurements performed in differentcountries can be easily compared. The internationally accepted guidance for the evaluation ofmeasurement uncertainty is the ISO “Guide to the Expression of Uncertainty in Measurement”
This document describes the principles on the evaluation of measurement uncertainty forcalibration and testing laboratories to meet the requirement of SNI-19-17025-2000 on ‘General Requirements for the Competence of Calibration and Testing Laboratories’
The method of evaluating measurement uncertainty described in this document is in accordance
with ISO “Guide to the Expression of Uncertainty in Measurement”.
This document gives the recommended method for evaluating measurement uncertainty that is applicable for calibration and testing laboratories which wants to be accredited by National Accreditation Body of Indonesia (KAN) based on SNI-19-17025-2000.
Regarding one of the important factors in the accreditation of calibration laboratories, that is Best Measurement Capability (BMC), this document also gives general guidance in evaluating BMC.Compliance testing sometimes involves measured values, which lie close to the zone ofuncertainty.

To assist laboratories in implementing the method in this document worked examples on the evaluation of measurement uncertainty for calibration and testing laboratories and the evaluation of Best Measurement capability will be given in Supplements.
