The dual-numbered designation of the measurement, control and laboratory equipment standard records that CENELEC adopted the international text without technical change, republishing it under both numbers with a foreword confirming the unmodified adoption and an annex relating it to the directive. The practical effect is that a test programme written against either designation, or against the international standard itself, is the same, and the difference lies in the citation used in the technical file and in the declaration of conformity. The document remains a product family standard, which means that it displaces the generic standards for every product within its scope, and in Europe it is issued in several parts so that the industrial case, the sensitive equipment case and in vitro diagnostic medical devices are treated separately. Because the equipment covered is used to measure, the acceptance criteria refer to the change produced in the measured quantity, and the manufacturer must state the criterion for each function in the test plan.
