ISO/TC 23/SC 7/WG 12 - Combine harvesters, forage and cotton harvesters

This document specifies terms and definitions related to combine harvesters and their component parts. It identifies dimensions and other characteristics aimed at allowing comparison of operations of the component parts, in association with ISO 8210, which lays down methods of measuring characteristics and performance requirements for the terms defined.

This document specifies a test procedure for the measurement and testing of combine harvesters. It applies to either self-propelled or trailed type, either directly cutting the crop or picking it up from a windrow, for use in several crops. This document specifies the terminology and methods to be used for measuring important characteristics of combine harvesters. It includes both functional and capacity tests, in other words, those conducted over an extended period when ease of operation, ease of adjustment, rate of work and general operating characteristics can be assessed, and those carried out on specific occasions for the determination of grain loss and capacity characteristics. It applies to all types of combine harvesters.

This document specifies terms and definitions related to forage harvesters and their component parts. This document identifies dimensions and other characteristics aimed at allowing comparison of operations of the machines and to improve communication among engineers and researchers, in association with ISO 8909-2, which lays down methods of measuring characteristics and performance requirements for the term defined.

This document specifies test methods for evaluations of forage harvester function and performance, covering forage harvesters which cut the crop directly at full width or from spaced-apart plant rows, or which pick up pre-cut crop. It applies to forage harvesters with driven knives for chopping and which deliver the chopped crop into a container or a separate vehicle or trailer. The forage harvesters can be tractor-mounted, trailed or self-propelled.

This document specifies the methods and requirements in assessing the dimensions and performance of a forage harvester, as defined in ISO 8909-1, and its functional components. It also allows comparison of forage harvester performance through comparative testing.

This document specifies a preferred method for determining and designating the capacity and unloading rate of combine harvester grain tanks and unloading systems.
