46、IFFERENCES National Differences from the text of International Electrotechnical Commission (IEC) Publication IEC 60730-2-9 are indicated by notations (differences) and are presented in bold text. There are ve types of National Differences as noted below. The difference type is noted on the rst line

47、of the National Difference in the standard. The standard may not include all types of these National Differences. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These

48、are national differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical 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 Di

49、fferences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE These are National Differences based on editorial comments or corrections. DR These are National Differences based on the national regulatory requirements. Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how t
