UN R48 — Supplement 12 to the 06 series of amendments

Paragraph 2. now groups the definitions under headings from “General” (2.1.) to “Colour” (2.11.), for example “Vehicle” (2.3.) and “Lamps” (2.5.). New paragraph 2.1.1. says that “the definitions given in this Regulation and its series of amendments” apply to the LSD, RID and RRD Regulations. These are the series of amendments “in force at the time of application for type approval”. The line “For the purpose of this Regulation:” is deleted. Paragraphs that refer to a definition now give other paragraph numbers. For example, paragraph 3.2.4. refers to the illuminating surface “as defined in paragraph 2.10.3.” instead of “paragraph 2.9.”.

New paragraph 2.4.14. defines headlamps of different “Classes”. New paragraph 2.4.15.1. defines the “Additional lighting unit”, for headlamps emitting a driving-beam and/or a symmetrical passing-beam for vehicles of categories L and T. New paragraphs 2.4.16. and 2.4.17. give definitions with regard to retro-reflectors and to retro-reflective marking, such as “Rear marking plate”. New paragraph 2.7.5. gives definitions with regard to AFS, such as “Bending mode” and “Functional unit”. New paragraphs 2.7.1., 2.7.2., 2.8.1. and 2.8.2. define “Aiming”, “Adjustment”, “Lens” and “Coating”. New paragraphs 2.10.8. and 2.10.12. to 2.10.17. define terms such as “Photometric stability has occurred” and “Coefficient of luminous intensity (CIL)”.

Paragraph 2.9.1. now says that a light source is “possibly assembled with one or more components to control the elements for visible radiation”. Before, it said that a light source “may be assembled with one or more transparent envelopes”. In paragraphs 2.9.1.4. to 2.9.1.6., the filament, gas-discharge and LED light source definitions now say “the only element for visible radiation”. The gas-discharge and LED definitions now say “electroluminescence”, and the LED definition adds “possibly completed with one or more elements for fluorescence-based conversion”. Before, these texts said “heated filaments”, “electro-luminescence/fluorescence” and “injection-luminescence/fluorescence”. In paragraph 2.9.2.1., a “Ballast” is now “one or more components” instead of “an electronic light source control gear”.

Paragraph 2.7.4.3. now says that a “Lighting mode” or “Mode” of a front-lighting function provided by an AFS means “a beam within the provisions either for one of the passing beam classes or for the main beam”. It is “designed and specified by the manufacturer for adaptation to dedicated vehicle and ambient conditions”. Before, a mode was “a state of a front lighting function provided by the AFS”. Paragraph 2.10.6. now gives two cases for the “Centre of reference”: (a) “The intersection of the axis of reference with the exterior light-emitting surface” or (b) “A point on or near a retro-reflective area”. The text adds that it is “designated to be the centre of the device for the purpose of specifying its performance”. It is still specified by the manufacturer of the lamp.

Many paragraphs now also refer to UN Regulations [LSD], [RID] or [RRD]. For example, paragraph 6.3. now reads “Front fog lamp (UN Regulation No. 19 or [RID])” and paragraph 6.5. reads “Direction-indicator lamp (UN Regulation No. 6 or [LSD])”. Paragraphs 6.1.2. and 6.2.2. now list option (b): headlamps type approved according to “UN Regulation [RID], Classes B and D headlamps only”. Option (a) is “UN Regulation No. 98 or 112, excluding Class A headlamp”. Many paragraphs now say “UN Regulation” instead of “Regulation”. Some sentences also change capital letters or punctuation, for example “Data set E1: The vehicle's speed exceeds 100 km/h”.

New paragraph 2.1.6. defines the “Change index”. It is a sequential number, starting from 0, specific to each lamp (function) covered by UN Regulations [LSD], [RID] and [RRD]. It indicates the number of times the new series of amendments to the pertinent UN Regulation have introduced higher stringency requirements for this lamp (function). New paragraph 5.33. covers a device type approved according to any preceding series of amendments to UN Regulations Nos. [LSD] and/or [RID] and/or [RRD]. Such a device is deemed equivalent to one approved according to the latest series when “the change indexes (defined in paragraph 2.1.6.) related to each individual lamp (function) do not differ”. In this case, the device may be fitted on the vehicle to be type approved without any update of “the device type approval documents and device markings”.

Paragraph 2.37., the definition of “External status indicator”, is deleted. The “Lamp” definition in paragraph 2.1.5. no longer lists the “external status indicator as defined in this UN Regulation” among the things that are not considered as lamps. The GRE session report ECE/TRANS/WP.29/GRE/82 records that this definition, introduced by Supplement 11, was left out of Supplement 12. GRE requested the secretariat to submit a rectifying document to the March 2020 sessions of WP.29 and AC.1. Paragraph 5.7.2.1. now covers single lamps “composed of two or more distinct parts”. Before, it covered single lamps “the apparent surface of which is composed of two or more distinct parts”.
