Описание (английский):

Specifies a test method for fertilizer distributors in lines, including distributors attached to a basic machine. Equipment designed for distributing microgranular pesticides or herbicides is excluded. Annex A tabulates a program of primary (mandatory) tests; annex B gives the determination of physical properties of fertiliziers; annex C describes optional tests; annex D contains an example of a test report.

Overview

ISO 5690-2:1984 - Equipment for distributing fertilizers - Test methods - Part 2: Fertilizer distributors in lines defines a standardized, reproducible test method for fertilizer distributors in lines, including units attached to a basic machine. The standard excludes equipment designed for distributing microgranular pesticides or herbicides. Its purpose is to harmonize performance evaluation so results (flow rate, metering accuracy, distribution evenness) are comparable across laboratories and products.

Key topics and requirements

Scope and exclusions: Applies to line (band) fertilizer distributors, including those twinned to tractors or basic machines; excludes microgranular pesticide/herbicide applicators.

Test types: Prescribes static tests (stationary drive wheel simulation) and mobile tests (machine in motion) to evaluate real-world performance.

Primary test program: Annex A lists mandatory tests covering effects of hopper level, flow rate, slope, bumps and operating speeds.

Measured parameters:

Evenness of flow rate and accuracy of metering (longitudinal and transverse distribution).
Flow rate expressed as mass or volume per unit time; application rate per unit length or area.
Determination of fertilizer physical properties (particle size, bulk density, water content, angle of repose) required in Annex B.

Test setup details:

Collectors: containers typically 500 × 500 mm with at least 150 mm depth; optional interlocking inserts to subdivide into cells for finer analysis.
Measurement protocol: e.g., five weight readings per test lasting 30 s each; methods for static drive-wheel speed calculation and mobile forward speeds (e.g., 1.50 m/s, 2.50 m/s).

Optional tests and reporting: Annex C describes optional additional evaluations (e.g., ground distribution), Annex D gives an example test report format. Test reports must document ambient humidity, fertilizer properties, machine configuration, and deviations from manufacturer specs.

Applications and who uses it

ISO 5690-2 is intended for:

Manufacturers of fertilizer distributors to validate design and provide certified performance data.

Test laboratories and certification bodies performing type approval, quality control and conformity testing.

Agricultural engineers, equipment purchasers and researchers who need reliable comparative data on metering accuracy, flow stability and sensitivity to hopper fill, speed, slope or bumps.

Tractor and implement test programs when distributors are evaluated in combination with a basic machine.
