Testing Items

Completion testing programs are built around the indicators written into the project contract, and commonly include the following categories:

• Power and energy performance: rated power, PTO power and torque, hydraulic lifting capacity, fuel consumption per unit of operating area, and energy efficiency of electric drives.
• Field performance: working width, effective field capacity, field efficiency, operating speed, and adaptability to crop, soil, and slope conditions.
• Seeding quality: seed spacing uniformity, qualified seeding rate, seed damage rate, seeding depth consistency, and miss and multiple seeding indices.
• Harvesting quality: total grain loss rate, broken grain rate, impurity rate, header and threshing losses, stubble height, and unbroken ear rate.
• Spraying performance: spray volume rate, distribution uniformity across the boom, droplet size spectrum, deposit density, and drift reduction performance.
• Tillage quality: average working depth, depth stability, soil burial rate, residue coverage, and surface levelness after operation.
• Reliability and durability: mean time between failures, effective reliability coefficient, failure classification statistics, and accumulated endurance test hours.
• Safety compliance: guarding and shielding, ROPS and FOPS strength, braking and steering, lighting and marking, operator station access, noise, and vibration exposure.
• Environmental compliance: non-road diesel engine exhaust emissions and external noise limits.
• Electrical and electronic performance: insulation resistance, electromagnetic compatibility, bus communication conformance, positioning accuracy, and auto-steer path accuracy.
• Material and component verification: hardness, tensile and impact properties, chemical composition, microstructure, coating thickness, and wear resistance of critical parts.

Testing Methods

Bench testing is used wherever parameters can be measured under controlled conditions. Engine and PTO performance is determined on dynamometer stands, seed metering devices are assessed on belt-type test rigs that simulate ground speed, spray distribution is measured on patternator benches, hydraulic components are exercised on flow and pressure test stands, and material properties are verified in the metallurgical laboratory using methods consistent with recognized standards such as ASTM A370 and ASTM E8 for metallic test pieces.

Field testing is indispensable for whole machines. Prototypes are operated on representative plots while working capacity, losses, fuel consumption, and quality-of-work indices are measured following the applicable GB/T and ISO test procedures, for example the GB/T 3871 series for agricultural tractors, GB/T 6973 for precision seed metering, ISO 8210 for combine harvester evaluation, and the ISO 5682 series for spraying equipment. Test conditions such as crop variety, yield level, grain moisture, and soil type are recorded so that results can be normalized and compared with the contracted indicator values.

Safety and environmental items are verified against GB 10395 and the ISO 4254 series for machinery safety, ISO 5700 for ROPS structures, and GB 20891 together with the ISO 8178 measurement cycle for non-road engine emissions. All measuring instruments are calibrated and traceable, and where a project indicator has no existing standard method, the laboratory develops a documented custom test protocol for confirmation by the acceptance expert panel.

Applications

Completion test reports from accredited third-party laboratories are used across the entire lifecycle of agricultural equipment research and industrialization:

• Acceptance review of national and provincial science and technology projects, key R&D programs, and special funding initiatives.
• Scientific and technological achievement appraisal, new product evaluation, and expert verification meetings.
• Supporting documents for science and technology progress award applications.
• Evidence for high-tech enterprise recognition, R&D expense deduction, and intellectual property filings.
• Preparatory data for agricultural machinery promotion appraisal and market access.
• Enterprise internal stage-gate reviews, design finalization, and small-batch production release decisions.
• Verification of government procurement, demonstration, and pilot projects involving new agricultural machinery.

FAQ

Why is third-party testing required for project completion?

Acceptance committees require objective evidence from an organization independent of the project undertaking unit. A test report from an accredited third-party laboratory eliminates self-declared data, ensures traceability of measurement, and gives the expert panel a defensible basis for judging whether the contracted indicators have been achieved.

What documents should be prepared before testing?

Typical submissions include the project contract or task book, technical indicator tables, design documents and specifications, prototype commissioning records, operating and maintenance manuals, and any prior internal test data. The laboratory uses these to draft the test outline and confirm the test methods with the project team.

Can testing be performed at our own test farm or factory?

Yes. Whole-machine field performance items are usually tested on plots provided by the applicant, provided crop, soil, and moisture conditions fall within the ranges specified by the applicable standards. Laboratory-dependent items such as dynamometer, bench, materials, and environmental testing are performed at fixed facilities.

How long does completion testing take?

For a single prototype with a defined indicator set, testing commonly takes several weeks, including outline confirmation, field or bench execution, and report preparation. Durability and reliability items that require accumulated operating hours should be scheduled well in advance of the acceptance meeting.

What if a prototype fails to meet an indicator?

The laboratory reports the measured values and the conformity conclusion. The project team may modify the design and request a retest of the affected items. Scheduling testing early leaves time for corrective iterations before the formal acceptance deadline.

Are the reports recognized nationwide?

Reports issued by laboratories holding national accreditation and inspection body recognition are accepted by government funding agencies, expert panels, and appraisal institutions across the country, and many reports are also usable for international cooperation under mutual recognition arrangements.
