Recent ISO activity within ASABE (updated 8/15/2014):

ISO/TC 23/WG4, Sustainability
A New Working Item Proposal has been approved (ISO 17989-1"Tractors and machinery for agriculture and forestry - Sustainability - Principles") with ~16 pages of comments. A new Working Group 4 has been established and the US has named the following five (5) experts: E.B. Smith (Deere), Dan Mustico (OPEI), D. Murray (AGCO), M. Lyons (CNH), and Tom Skove (MTD). It is expected that this basis document will lead to sustainability projects from the various working groups.
ISO/TC 23/SC 2 (Common Tests) Updates 2012-09
Update on ISO 5700, "Tractors for agriculture and forestry - Roll-over protective structures - Static test method and acceptance conditions." A decision was made to modify the text of ISO/OECD 5700 to remove clause 14 (Extension) and have the text proceed to DIS balloting. The US approved the July DIS ballot with 5 pages of comments.
Efforts continue on harmonization of ISO 3776-2:2007, "Tractors and machinery for agriculture - Seat belts - Part 2: Anchorage strength requirements" with the associated OECD Codes. The US approved the recent DIS ballot with comments. Overall results will be available in late October.
A DIS ballot is currently open on ISO/DIS 12934-1 is "Tractors and machinery for agriculture and forestry - Definitions." This ballot will close early next year.
Part 2 (Codification for road-use) is related to classification for on-road use and may be published as a Technical Report. No further activity on this has been made available by ANSI.
A ballot is open to publish the current draft of 27850 "Tractors for agriculture and forestry - Falling object protective structures - Test procedures and performance requirements. A second DIS ballot closed in August and the US approved the draft with comments.
ISO/TC 23/SC 3 (Safety) Updates 2015-02

ISO has approved four new projects to develop or revise documents in the ISO 4254 series of standards for agricultural machinery. Press release (PDF).

More details on the portable grain conveying equipment project - ISO 4254-16 are available. Press release (PDF).

ISO/TC 23/SC 4 (Tractors) Updates 2012-09
The most recent International meeting of ISO/TC 23/SC 4, "Tractors and Machinery for Agriculture and Forestry - Tractors" was held in Oostende, Belgium in March of 2011. Rumors of a meeting early next year have not been confirmed.
Voting on the second DIS 12933, "Agricultural tractors -- Requirements for braking" closed and it was approved by a very close margin. Many comments were submitted by several nations. The US disapproved and submitted comments. Strategies continue to ensure the comments of the US and other nations are considered prior to moving this project forward.
The two New Work Item Proposals for the Slow Moving Vehicle Identification Emblem (SMV) and the Speed Indicating Symbol (SIS) were approved by the US TAG and International Committees. Ballots for a Committee Draft (CD) are expected soon, and a draft of the SIS component has been made available.
New projects related ISO 500-1 and -3 (PTO general and PTO master shield) were balloted and the US voted to approve both. Overall vote results have not been published.
A ballot on an amendment for ISO 730 Agricultural wheeled tractors - Rear-mounted three-point linkage - Categories 1N, 1, 2N, 2, 3N, 3, 4N and 4 closed recently and the results are expected soon. The US had voted in support of this amendment.
The amendment would replace Figure 2 and Table 2 related to the distance from PTO to lower link points.
A ballot for an NWIP to revise ISO 23205 (Instructional seat) is currently available for review and vote. The proposal would revise references so that the standard could be adopted without deviations to prescriptive clauses.
Ballots are finally available for ISO 5721 -1 and -2 (Tractors - field of vision to the front and field of vision to the side and rear) These are DIS ballots and voting closes at the end of the year.
  • This work is moving forward and is tied to related work in ISO/TC 23/SC3. The SC3 work activities are for non-tractor agricultural equipment and will begin when parts 1 and 2 reach DIS.
ISO/TC 23/SC 6 (Crop Protection - Spray) Updates 2012-09
This committee recently held a Plenary in China and the US was well represented. Continued emphasis on drift management, chemical use optimization, and worker exposure are apparent.
ISO/TC 23/SC 7 (Harvest Equipment) Updates 2012-09
A DIS ballot is currently open for ISO 5718 (Rotary Blade Requirements) and will close mid-November.
The part 14 bale-wrapper safety project is somewhat stagnant.
The 2012 version of "Agricultural machinery - Safety - Part 13: Large rotary mowers" was published in August.
ISO/TC 23/SC 14 (Symbols, displays, and manuals) Updates 2012-09 The 2012 International meeting was held in February (Paris). Many new symbols are to be considered including but not limited to the area of PTO speed & direction, emissions, powered lawn & garden equipment, agriculture equipment, and forestry equipment. There are currently five (5) ballots open on the various symbols and will close mid-October.
ISO/TC 23/SC 19 (Ag electronics) Updates 2012-09
The dynamic activities within ag electronics (serial control & data network, GPS, and animal ID) continues. The safety implication of their activities are apparent, but will not be reported here.

ISO/TC 238 (Solid biofuels) Updates 2014-08
The first seven parts of ISO 17225 are complete! Press release (PDF).

ISO has approved a new project to develop a standard for thermally treated and densified biomass fuels. The project is designated as ISO 17225-8. Press release (PDF).

ISO TC 283 met in Stockholm recently and made great progress toward developing several standards. Read about it in our press release (PDF).
