MAIN RESOLUTIONS TAKEN AT 3RD PLENARY MEETING JUNE 24TH, 2016 TOKYO, JAPAN RESOLUTION #60 SC41 UNANIMOUSLY AGREED TO ASK ISO/CS TO SEND ISO/FDIS 14469 FOR PUBLICATION RESOLUTION #61 SC41 UNANIMOUSLY AGREED TO ASK ISO/TC22 TO SEND A NWIP FOR ECU. IT IS AGREED TO TAKE ALL THE ASPECT ALREADY TREATED IN UNECE R110 AND R115. THE SCOPE IS THE FOLLOWING: THIS INTERNATIONAL STANDARD SPECIFIES TESTS AND REQUIREMENTS FOR THE ELECTRONIC CONTROL UNIT, A NATURAL GAS FUEL SYSTEM COMPONENT INTENDED FOR USE ON THE TYPES OF MOTOR VEHICLES DEFINED IN ISO 3833. THIS INTERNATIONAL STANDARD IS APPLICABLE TO VEHICLES (MONO-FUEL, BI-FUEL OR DUAL-FUEL APPLICATIONS) USING NATURAL GAS IN ACCORDANCE WITH ISO 15403. RESOLUTION #63 SC41 UNANIMOUSLY AGREED TO ASK ISO/CS TO PURSUE THE CREATION OF A JOINT WORKING GROUP WITH TC197 WG18 TO DEVELOP ISO 19882 (GASEOUS HYDROGEN -- LAND VEHICLE FUEL TANKS -- THERMALLY ACTIVATED PRESSURE RELIEF DEVICES). RESOLUTION #77 SC41 UNANIMOUSLY AGREED TO MODIFY TITLE OF WG7 FROM " ROAD VEHICLES GENERAL SAFETY REQUIREMENTS FOR GASEOUS FUELED VEHICLES TO "ROAD VEHICLES GENERAL SAFETY REQUIREMENTS FOR GASEOUS FUELED VEHICLES AND TERMINOLOGY AND TO INCLUDE ISO/PWI 21059 "ROAD VEHICLES -- SPECIFIC ASPECTS FOR GASEOUS FUELS -- TERMINOLOGY" IN THE WG7 WORK PROGRAMME.
MAIN RESOLUTIONS TAKEN AT 3RD PLENARY MEETING JUNE 24TH, 2016 TOKYO, JAPAN RESOLUTION #78 SC41 UNANIMOUSLY AGREED TO INVESTIGATE THE POSSIBILITY TO LAUNCH A NWIP RELATED TO "QUALIFICATION OF PERSONNEL FOR INSTALLATION, MAINTENANCE AND SERVICE OF GASEOUS FUELED VEHICLES". RESOLUTION #81 SC41 UNANIMOUSLY AGREED TO SEND A CIB INSIDE SC41 IN ORDER TO KNOW THE INTEREST OF PREPARING CONFORMITY ASSESSMENT STANDARD (CASCO) FOR CNG COMPONENTS. RESOLUTION #83 SC41 UNANIMOUSLY AGREES TO FURTHER INVESTIGATE WITH ISO/TC8 SHIPS AND MARINE TECHNOLOGY / SC8 SHIP DESIGN TO ESTABLISH A JWG WITH ISO/TC22/SC41/WG7 IN ORDER TO COVER STANDARDIZATION OF FUEL SYSTEM ON BOATS TO HARMONIZE THE IMO REQUIREMENTS FOR THE USE OF CNG, LNG AND BIOMETHANE.
