• Engine and PTO performance: rated power, maximum torque, torque backup, governor characteristics, and speed ranges per the ISO 789 series
• Drawbar performance: traction force, drawbar power, wheel slip, and ballasting effects under defined track or field conditions
• Fuel consumption: specific fuel consumption at rated and partial loads, fuel consumption per hectare during field operations
• Hydraulic performance: lift capacity, hydraulic power, flow rate, pressure, and working pressure stability
• Field capacity and work quality: effective field capacity in hectares per hour, operating width, working depth consistency, and seed or fertilizer distribution uniformity
• Grain loss and damage: header loss, threshing loss, separation loss, and grain breakage for harvesting machinery
• Spray performance: volume distribution pattern, coefficient of variation, droplet size, nozzle flow rate, and drift potential
• Operator safety and ergonomics: guard and shield compliance, ROPS and FOPS structural strength, emergency stop function, noise at the operator position per ISO 5131, and whole-body vibration per ISO 5008
• Electrical and electronic safety: insulation resistance, grounding continuity, protection against water and dust, and control circuit reliability
• Reliability and durability: mean time between failures, wear of critical components, and structural integrity after extended operation cycles
• Environmental performance: exhaust emissions of diesel engines and noise emission levels at bystander positions

Testing Methods

Testing is conducted using a combination of laboratory bench methods, instrumented track testing, and field trials, depending on the product type and applicable standard.

• Bench and dynamometer testing: engine and PTO performance curves are measured on dynamometer test stands following ISO 789-1 and ISO 789-2, with calibrated torque, speed, temperature, and fuel consumption instrumentation.
• Drawbar testing: traction performance is measured on a standard test track or prepared field per ISO 789-9 and the OECD tractor test codes, covering multiple gears and ballast configurations.
• Hydraulic testing: lift capacity and hydraulic output are determined using calibrated load cells and flow-pressure measurement circuits per ISO 789-2 and related hydraulic test procedures.
• Functional bench testing: seed distribution is measured on test stands with grease belts or rotating carousels, and spray distribution is measured on patternators in accordance with ISO 5682 series procedures.
• Field performance trials: machines operate under documented crop, soil, slope, and moisture conditions while data loggers record speed, area covered, fuel use, losses, and work quality indicators.
• Safety and structural testing: ROPS and protective structures undergo static and dynamic loading per ISO 3463 and ISO 5700, and safety distance and guarding requirements are verified against ISO 4254 and GB 10395.
• Environmental and electrical testing: electronic devices undergo ingress protection, temperature cycling, vibration, and electrical safety testing referenced to IEC standards.
• Data analysis and reporting: measured results are corrected to standard atmospheric conditions where required, uncertainties are calculated, and conclusions are compared against the limit values defined by the applicable standards or the manufacturer's declared specifications.

FAQ

What is agricultural technology performance testing?

It is the systematic measurement and evaluation of the power, capacity, work quality, safety, reliability, and environmental characteristics of agricultural machinery and equipment, performed according to standardized procedures by qualified laboratories.

Which standards are most commonly applied?

Frequently applied standards include the ISO 789 series for tractor test procedures, the ISO 4254 series for machinery safety, the ISO 16119 series for sprayers, the ISO 5682 series for spraying equipment, GB/T 3871 and GB 10395 national standards, and the OECD Standard Codes for official tractor testing.

How long does a typical performance test take?

Simple functional bench tests may be completed within a few days, while full tractor or harvester performance evaluations that combine bench testing, track testing, and multi-season field trials can take several weeks to several months depending on crop availability and the test program scope.

What should be prepared before submitting a machine for testing?

The client normally provides the machine with technical specifications, operating and maintenance manuals, declared performance parameters, and information about intended operating conditions. The laboratory then confirms the applicable standards, test plan, and schedule before testing begins.

Can testing be performed on-site or in the field?

Yes. Many performance parameters, such as field capacity, fuel consumption per hectare, grain loss, and spray drift, must be measured under real operating conditions. Accredited laboratories can deploy mobile instrumentation teams to farms, test stations, or demonstration sites.

Why should testing be entrusted to accredited third-party laboratories?

Accredited laboratories provide technically valid, impartial results recognized by regulators, certification bodies, and international buyers, reducing commercial risk and supporting smooth market access for manufacturers and exporters.
