Standards Development
This document identifies and defines terms, specifies a means of classification, provides dimensional characteristics, and gives a nomenclature of components for mulching equipment (in other words, mulching attachment carriers and mulching attachments) used in forestry and related operations. Its aim is to establish a uniform method of describing the various configurations of these types of forestry machines.
Machines for mulching designed for feeding by hand are not covered by this document.
ISO 21120 was an accepted work item (AWI) in 2016 that unfortunately lost its project leader and was eventually cancelled in 2019. The project was picked up again in 2021 by a group of experts from North America and the scope was slightly expanded to include some basic commercial specifications.
The NWIP ballot failed in 2023 as too few P-members nominated experts. The situation has now improved and project is ready to be re-balloted. The draft has been updated according to the resolved NWIP ballot comments.
