News, Status Reports from ASABE

The American Society of Agricultural and Biological Engineers (ASABE) has completed the adoption of an international standard, ISO 4254-6:2020, for agricultural sprayers and liquid fertilizer distributors.

Designated ANSI/ASABE AD4254-6:2020 FEB2021, Agricultural machinery—Safety—Part 6: Sprayers and liquid fertilizer distributors, the adoption aligns North American design practices for such equipment with the updated international standard.

ASABE members with standards access and those with site-license privileges can access the standard electronically. Go to elibrary.asabe.org.

John Fisher, the Association’s safety standards consultant, has contributed this additional information on ASABE standards.
