Q1What changed7 changes
Symbols and the letters “PL” (paras. 3.3.2.4. and 3.3.2.4.4.)
Paragraph 3.3.2.4. now reads “Symbol(s), according to Table 1, and additional symbol(s), if any”. Before, it read “Additional symbols for headlamps, AFS and front fog lamps”. Under paragraph 3.3.2.4.4., the letters “PL” apply to front fog lamps, headlamps and AFS installation units incorporating an outer lens of plastic material. Before, the text said “a lens” instead of “an outer lens”, and “the lighting” instead of “the function(s)”.
New symbol “T” for AFS (para. 3.3.2.4.8.)
For AFS, paragraph 3.3.2.4.8. adds the symbol “T” after the symbol(s) of all lighting function(s) and/or class(es) designed to comply with bend lighting provisions. These symbol(s) are arranged together and leftmost to the symbol “T”.
Communication form item for the luminous flux of an AFS (para. 4.5.2.6.)
For an AFS incorporating light sources and/or LED module(s) producing the basic passing beam, paragraph 4.5.2.6. now refers to item 9.3.3.(a) of the communication form. The total objective luminous flux of the lighting units is the one indicated under that item. Before, the paragraph referred to item 9.3.2.3. When this flux exceeds 2,000 lumen per side, a reference must be made in the communication form in Annex 1, as before.
New drawings in Figures A4-V and A4-VII
Figures A4-V and A4-VII have new drawings. The proposal states that it corrects the locations of points 50L and 75L in these figures.
Word “degrees” in Figure A4-VII
In Figure A4-VII, the text on angular positions of passing-beam photometric requirements now says “degrees” instead of “deg”.
