Correlation Issue in Section No. F.1

Reason: The Technical Committee edits the text in line with a review conducted by the Correlating Committee and for consistency with Chapter 12. Class R and Class S have been removed from Chapter 12 and Class N has been added. The above text will harmonize accordingly.

FR 4531

Table Modification in Section No. A.14.6.2.4

Reason: The Technical Committee modifies column GG and replaces "exterior strobe" with "exterior visible notification appliance". This is done as part of the Correlating Committee Task Group on terms, the term "light" and “strobe” was reviewed throughout the entire document for proper use. In some cases it refers to a physical appliance while other sections use it to refer to the output of an appliance. In this section the term is for an appliance and the proper term "visible notification appliance" should be used.
