Abstract: Several types of commercial 100-Omega resistors can be used with the cryogenic current comparator to maintain the resistance unit, derived from the Quantized Hall Effect (QHE), and to disseminate this unit to laboratory resistance standards. Up until now, the transport behaviour of these resistors has not been investigated. Such an investigation is of importance for carrying out comparisons that are close to the level of a direct comparison of two QHE apparatuses. A set of five 100-Omega resistors from three different manufacturers has been sent to 11 participating national metrological institutes. All laboratories but one has measured the resistors based on their laboratory's quantized Hall resistance measurements. A constant drift model has been applied, and the results are evaluated in such a way that the transport properties of these resistors are treated independently for the different types of resistor. Under certain conditions, these resistors allow comparisons with uncertainties better than 1 part in 10(8).
