Round-robin test

In experimental methodology, a round-robin test is an interlaboratory test performed independently several times. This can involve multiple independent scientists performing the test with the use of the same method in different equipment, or a variety of methods and equipment. In reality it is often a combination of the two, for example if a sample is analysed, or one of its properties is measured by different laboratories using different methods, or even just by different units of equipment of identical construction.
