-Presentation by ISO – ISO 16254 / SAE J 2889-1 Development Status
A review of actions and conclusions since the last QRTV IWG meeting was given:

-ISO WG42 meeting was held in Warsaw to review issues identified in ballot
comments as well as issues identified in SAE comments to NHTSA NPRM.

-A SAE/ISO meeting was held to review testing work conducted for the purpose of
evaluating the draft text for technical accuracy, practicability, and clarity.

-Testing indicates both overall SPL and 1/3 octave results can be measured and reported with sufficient precision.

-Proper treatment of modulated signals remains as an outstanding topic.

-Pitch shift can be measured and reported with sufficient precision.
-Using the maximum in each 1/3 octave band, and the overall SPL, as the basis for determining if a test facility is acceptable is a practical and feasible specification.

-Narrowband measurement indoors with simulated vehicle speed provides means to accurately and precisely identify frequency shift.

Planned future work includes:
  -July-September 2013: Continuing technical evaluations
  -October 2013: ISO WG42 meeting to evaluate draft text (China).
  -In 2014
    -Continue technical work as identified: Resolution of any identified technical issues.
    -Incorporation of any comments from QRTV IWG or GRB regarding fitness for purpose.
    -Expect ISO DIS document submitted for ballot in 2014.
