ASABE Revises Two Standards

The American Society of Agricultural and Biological Engineers (ASABE) has initiated a project to replace an ASABE standard on combine harvesters with a parallel ISO standard.

ASABE also has completed a revision of Part 3 of the standard series to improve air-quality systems of agricultural cabs.

The document on combine harvesters, ISO 5687:2018, Equipment for harvesting—Combine harvesters—Determination and designation of grain tank capacity and unloading device performance, was revised with input from ASABE members, demonstrating the commitment among engineers and farmers to have a consistent and analytical procedure for measuring grain tank capacity and unloading rate. ISO 5687:2018 will replace the earlier version adopted identically by ASABE in 2004, and readopted with deviations in 2014.

The second revision, ANSI/ASABE S613-3.1, Tractors and self-propelled machinery for agriculture—Air quality systems for cabs—Part 3: Filters for
environmental cab HVAC systems, includes modified acceptance levels and test conditions for the vapor test, as well as clarified wording.
