Supplement 3 to the 01 series of amendments to UN R 98, 112, and 123 deleted the measurement point HV from the photometric requirement table. The HV measurement point, however, remains a requirement for checking photometric stability. This proposal removes the HV measurement point from the photometric stability requirements for the passing beam. The HV measurement point remains a valid for the driving beam.
12. The expert of GTB introduced a proposal for amendments to Regulations Nos. 98, 112 and 123 to delete the measurement at the HV point during the test for stability of photometric performance of the passing beam (ECE/TRANS/WP.29/GRE/2016/25). GRE adopted the proposals as draft supplements and decided to submit them to WP.29 and AC.1 for consideration and vote at their March 2017 sessions as part of the consolidated amendment proposals (see para. 10 above).
