In Friday 26th October’s Federal Register, NHTSA published a Notice of Proposed Rulemaking (NPRM) to update 49 CFR, Part 595 – Make Inoperative Exemptions. See http://1.usa.gov/R8c8rE.
Part 595, Subpart C has provisions for vehicles that are modified to accommodate people with disabilities. The modifications may take a vehicle out of compliance with a FMVSS and Subpart C contains exemptions that allow this.
This NPRM is in response to a Petition for Rulemaking following the publication of FMVSS 226 – Occupant Ejection Mitigation and would add a new exemption to allow changes to the vehicle seat which may take it out of compliance with 226. (FMVSS 214 is already included).
They propose to make this effective within 180 days of publication of the Final Rule. (Note: the FMVSS 226 phase-in starts on 1st September 2013).
Comments can be submitted in the docket ( NHTSA–2012–0149) until December 26th 2012.
EU Directive 2006/40 requires new types of vehicles after 1st January 2011 and all vehicles after 1st January 2017 to be fitted with an air conditioning system that uses a refrigerant with a Global Warming Potential (GWP) less than 150. R134a is approx 1300 and 1234yf is 4.
In addition, the Commission published a letter (http://bit.ly/XaudLn) that deals with the shortage of 1234 yf.
CAFE: The first phase, from MYs 2017–2021, includes final standards that are projected to require, on an average industry fleet wide basis, a range from 40.3–41.0 mpg in MY 2021. NHTSA are only authorised to publish 5 years in a single rule making so 2022-2025 will be published in a separate action.
EPA is establishing standards that are projected to require, on an average industry fleet wide basis, 163 grams / mile of carbon dioxide (CO2) in model year 2025, which is equivalent to 54.5 mpg if this level were achieved solely through improvements in fuel
Apologies for the lateness of this post. The last 3 months have been incredibly busy (i spent some time travelling in SE Asia and relocated from Malaysia to San Francisco, California to start a position at Tesla Motors) and my blog was one of the many things i have to put on hold. Now that i am more settled here i have the time to keep up to date.
Anyway, below are the things that have been published in those 3 months;
Amends 692/2008 (Emissions & RMI) adding specific sections about vehicle feulled by hydrogen or a mixture of hydrogen and natural gas. Also requires additional information for electric vehicles to be included in the information document.
The main purpose of the GTR was to align the glazing optical, mechanical and environmental resistance requirements that existed in the US, ECE and Japan as they are all substantially similar. This will assist manufacturers in designing and testing glazing components that are acceptable in the major markets.
FMVSS 205 is a short standard as the main requirements from ANSI Z26.1 are incorporated by reference. This NPRM would contain all the text from the GTR, removing the reference.
While all the mechanical, optic and environmental tests are updated with minor amendments, NHTSA believe that the main advantage to adopting the requirements are an upgraded fragmentation test designed to better test the tempering of curved tempered glass, and a new procedure for testing an optical property of the windshield at the angle of installation, to better reflect real world driving conditions.
NHTSA propose a compliance date of 1 year after the publication of the Final Rule as the changes are minor and they believe that manufacturers will be able to comply with current systems.
Comments are due in the docket (NHTSA-2012-0083) by 20th August 2012.
