ISO/PWI 21120 Machinery for forestry — Forestry mulching equipment — Identification terminology, classification, component nomenclature, and commercial specifications

Scope

This document identifies and defines terms, specifies a means of classification, provides dimensional characteristics, gives nomenclature of components, and provide commercial specifications for mulching equipment (in other words, mulcher carriers and mulcher 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 and not covered by this document.

Purpose

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.
