What is ISO 8893 about?
ISO 8893 discusses portable brush cutters and grass trimmers as a part of forestry machinery
ISO 8893 specifies a method for testing the performance and fuel consumption of internal combustion engines used to power portable brush-cutters and grass trimmers.
Who is ISO 8893 for?
ISO 8893 on engine performance and fuel consumption are applicable for:
- Manufactures for portable machines such as brush cutters and grass trimmers
- Companies dealing with brush cutters and grass trimmers machines
- Suppliers and distributors for brush cutters and grass trimmers machines
- Service providers for portable machines
Why should you use ISO 8893?
Forestry Machines are heavy equipment machines that are used to move logs and trees from the stump to the roadside log landing like log loaders, mulchers, stump grinders, feller bunchers, declaimers, etc.
A brush cutter machine is an agricultural tool that is used to harvest crops, trim small trees, etc whereas a grass trimmer is used as a garden tool for cutting grass, small weeds and groundcover.
ISO 8893 provides you with the measurements for engines and fuel such as: engine speed which has +2% of measured speed, fuel consumption having +2% of measured consumption, fuel temperature containing +2 °C and engine inlet air temperature having +2 °C to assist in manufacturing the portable brush cutter and grass trimmers forestry machinery in a qualified manner.
ISO 8893 is used as a basis for the calculation of engine performance and fuel consumption of portable brush cutters and grass trimmers to enhance the quality and efficiency of the equipment.
Regularized testing by adopting ISO 8893 can help in enhancing the value of a product by keeping it up to date.
