What is ISO 8909‑2 about?
ISO 8909‑2 discusses the specification of characteristics and performance for forage harvesters.
ISO 8909‑2 is the second part in a multi-part series that specifies the methods and requirements for assessing the dimensions and performance of a forage harvester, and its functional components. It also allows the comparison of forage harvester performance through comparative testing.
Who is ISO 8909‑2 for?
ISO 8909‑2 on the specification of characteristics and performance for forage harvesters is applicable to:
- Manufacturing for harvesting machines 
- Companies dealing with harvesting machines and forage harvesters
- Suppliers and distributors for forage harvesting machines 
Why should you use ISO 8909‑2?
Manual harvesting is slow and done using simple hand tools such as sickles and knives. That’s why mechanized machines are used in harvesting to increase the output of crops harvested and save time along with enhancing the quality of the final product.
ISO 8909‑1 assist you in getting familiarized with forage harvesters and functional components of harvesting equipment by providing you with the specification of characteristics and performance for forage harvesters and components.
ISO 8909‑1 assist you by providing a basis for comparison of operations of the machines and thus assists in enhancing the quality and efficiency of forage harvesters and functional components.
What’s changed since the last update?
BS ISO 8909‑2:2021 supersedes ISO 8909‑2:1994, which is withdrawn. The main changes with respect to the previous edition are:
- Updates to normative references
- The precision of description of forage harvester characteristics
