| Document Title | UN R128: Proposal for Supplement [8] | ||||||||

| Summary | The current text of UN R128, Annex 4, paragraph 1.2. allows only for a decrease of luminous flux from 1 minute to 30 minutes. This has proven to be unnecessarily design restrictive as the drive electronics in a stabilized light source can lead to a slight increase in the luminous flux from 1 minute to 30 minutes. Therefore, this proposal would allow a limited increase of luminous flux from 1 minute to 30 minutes within the given minimum and maximum requirements. This proposal relates to document GRE/2018/48 retaining requirements for LR4 category light sources which would otherwise have been impacted by the present proposal. | ||||||||

22. The expert of GTB introduced amendment proposals that modified light source category LR4 in UN Regulation No. 128 and in the Consolidated Resolution R.E.5 (ECE/TRANS/WP.29/GRE/2018/48, ECE/TRANS/WP.29/GRE/2018/49 and Add.1). GRE adopted the proposals and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2019 sessions as draft Supplement 9 to the original version of UN Regulation No. 128 and draft amendment 3 to R.E.5. GRE noted that both amendments are part of the same package and should enter into force on the same date. |
