Abstract

This paper describes a study on the transportation effect using four 100 Ω standard resistors of a new construction. All resistors have been transported by air: two of the resistors in hand-carried luggage and the other two by normal air freight. The standards have been measured by three national metrology institutes, the Korean Research Institute of Standards, the National Institute of Standards and Technology in USA and the National Metrology Institute of Japan by means of their primary national standards based on the quantum Hall effect. No noticeable difference between the two transportation methods has been detected within a standard uncertainty of 0.01 µΩ/Ω and performance suitable for international comparisons of this type of resistors has been demonstrated.
