55. The expert from Japan, GRSP ambassador on IWVTA, introduced GRSP-52-10 showing a list of priority of discussion of candidate UN Regulations to be included in the IWVTA. GRSP requested its experts to provide detailed comments by its May 2013 session.
GRPE
Air-conditioning system was prioritized © because there is no corresponding UN Regulation for air-conditioning system. However, consideration of air-conditioning system is in progress in GRPE from two different aspects, i.e., (i) reducing CO2 emissions and improving overall efficiency, and (ii) test methods to measure leakages of fluorinated greenhouse gases from certain air conditioning systems (EC Regulation 706/2007 and EC Directive 2006/40).
GRB
The responsible organizations to review the UN Regulations for GRB are as follows;
-R28 “Audible warning” prioritized (a): CLEPA
-R51 “Permissible sound level” prioritized (b): OICA
(OICA will perform preliminary review by the next GRB session.)
-R117 “Tire rolling noise/RR” prioritized (a): ETRTO
GRRF
-R13H prioritized (b); OICA will take the role to split R13H into three pieces. i.e., “Braking”, “ESC” and “BA”.
-R79 Steering effort” was prioritized (a) if “LKAS” is not be part of R79.
-ETRTO agreed to sponsor the work of “Tire installation” prioritized (b). OICA committed to provide support to ETRTO in this exercise, as this will be a vehicle regulation. The new Regulations will be formulated based on the EU Directive on tire installation.
-R89 “Speed limiters” was prioritized ©.
-R55 “Coupling” was prioritized © because the equipment rate of coupling is as low as 10%.
-It is expected that four documents on “Braking”, “ESC”, “BA” and “Tire installation” will be provided by OICA hopefully before this summer.
GRSG
-Some Contracting Parties at GRSG questioned the opportunity of adding national requirements into UN regulations for the sake of introduction into IWVTA.
-Japan responded that even if the national requirements are proposed to be added into UN Regulations, they will probably not be approved by the respective GRs without legitimate justification.
GRSP
R25 “Head Restraint System”, R94 “Frontal Impact” and “FCV” were prioritized as (b). These activities are in progress by respective Informal Groups.
GRE
No information is available at the moment.
50. GRSP confirmed that GRSP-52-10 already included the amendments agreed upon by its experts on the proposal dealing with design/control principles of Advanced Driver Assistance Systems (WP.29-157-06) and no further comments were provided.
