OS GSO ISO 7256-2:2013 Scope

This part of IS0 7256 specifies a test method for seed drills for sowing in lines, including seed drills attached to a basic machine. The test method permits the determination of performance using reproducible tests so that comparable results in numerical or graphical form which take into account the influence of the following can be obtained: - type of speed - the forward speed - the level of seed in the hopper; - the application rate adjustment; - the slope of the ground; - the condition of the soil surface (bumps). The mandatory tests do not give any picture of the true distribution of the seeds on the sowing site
