D2 These are national differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical
43、substantiation (for the IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard.
44、 DE These are National Differences based on editorial comments or corrections. Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC tex
