Abstract To ensure the reliable assessment of laboratory measurement capability,a small scale inter-laboratory comparison was organized. In this comparison the design of scheme arrangement and samples, the distribution testing of data received, the determination of reference values, the performance judgment and analysis of laboratory results were considered. It was also studied on how to reduce the influence of collusion and enhance the scientific rigorousness of inter-laboratory comparison for chemical measurements.
