Components contributing less than 1/5 to 1/3 of the tot asurement uncertainty will not usually have much impact on the total measurement uncertainty. Even where reliance is to be made on over cision data or where note of clause of ISO/IEC 1705 is to apply, the laboratory should at least attempt to identify all significant mponents.
