They're, at the moment, broken down into addenda (some are simply a sentence fragment correction).
A full updated comprehensive revision using the new phraseology is coming in the next year (limited information can be seen in the GRE section).

Do you have a more narrowed down link? Or an article/paragraph where the text is that you displayed?

If still in doubt, F90 isn't available with Headlamp Cleaning and the Principle Passing Beam on the inboard unit is at 3448.9lm measured at the hotspot point.

It doesnt work that way.
Lumen (lm) is per definition the total output of a light source.
https://en.wikipedia.org/wiki/Lumen_(unit)
That is, per definition, not possible to 'measure at the hot spot'.
What you mean is the physical unit Candela, the physical unit for luminous intensity.
https://en.wikipedia.org/wiki/Candela
But that falls outside of the regulations I believe.
This is a commonly made mistake. |
Sure when I have a chance. It's a PITA to use that site on my phone. I do remember its an addendum to be republished with 4-8 paragraphs specifically for the cleaning system struck out and to be replaced.
Hotspot was the wrong choice of adjectives so I edited to Mid Field (the 25m - 50m distance of Zones II and IV).
Candela is the primary unit used for vehicle photometries.
