| Test Method Compatibility | ISO 2248 ASTM D5276 ISTA 3A | ISO 2248 and ASTM D5276 cover free-fall drop testing of packaged products or loaded containers. ISTA 3A is a general simulation test for packaged-products shipped through a parcel delivery system. | Confirm that the machine can reproduce the required drop orientation, drop sequence, package support condition, and test procedure for the target standard. | A written compliance matrix showing each required test step, applicable standard clause, machine function, and operator procedure. |
| Drop-Height Capability | Applicable product specification and selected test standard | Drop height is not a universal pass/fail value. It depends on package mass, package dimensions, distribution environment, and the selected test method. | Compare the supplier’s height range with the highest height required by your test plan. Check whether height is set mechanically, electronically, or by a calibrated position reference. | Factory measurement record, height-setting verification, and a repeatability test at several representative heights. |
| Height Measurement Accuracy | Test-method requirement and the laboratory’s internal measurement procedure | The reference height should be clearly defined, such as the distance from the intended impact surface to the lowest point of the package before release. | Ask how height is measured, where the reference point is located, and whether the displayed value can be independently checked with a traceable measuring instrument. | Calibration certificate or verification report identifying the instrument, measurement range, uncertainty, date, and traceability. |
| Release Accuracy | Applicable drop-test procedure | A suitable release mechanism should allow the package to fall without adding intentional horizontal force or restricting the required orientation. | Check whether the release is pneumatic, electromagnetic, or mechanical; whether it supports multiple orientations; and whether the mechanism is suitable for the package’s size and mass. | Video verification, repeated-release results, and an inspection record confirming that the package leaves the fixture cleanly. |
| Load Capacity and Platform Size | Product specification matched to the test sample | Rated capacity must cover the complete loaded package, including the product, cushioning materials, inner packaging, and outer container. | Verify maximum load, allowable package dimensions, center-of-gravity limitations, impact-surface dimensions, and any restrictions on unusually flexible or irregular packages. | A signed technical datasheet and a test demonstration using a sample with comparable mass and dimensions. |
| Impact Surface and Structural Stability | Applicable test method and laboratory floor requirements | The impact surface should be rigid, level, securely supported, and capable of withstanding repeated impact without unacceptable movement or deformation. | Review impact-plate material and thickness, frame construction, anchoring requirements, leveling method, and maintenance access. | Installation inspection, levelness check, anchoring record where required, and periodic structural inspection. |
| Repeatability and Reproducibility | Laboratory quality system and selected test method | Consistent results require stable height control, reliable release timing, repeatable orientation, and controlled package preparation. | Request repeated drops at the same setting and ask how the supplier controls variation in height, release, impact location, and operator setup. | Repeatability report containing test conditions, number of repetitions, measured values, deviations, and acceptance criteria agreed in advance. |
| Control and Data Recording | Laboratory procedure and customer data requirements | Useful records may include sample identification, package mass, dimensions, drop height, orientation, sequence, date, operator, and test result. | Check whether the controller supports recipe storage, user access levels, test-step logging, data export, and protection against accidental parameter changes. | Example test report, exported data file, user-access demonstration, and confirmation of backup or retention procedures. |
| Guarding and Interlocks | Applicable machinery-safety requirements and site risk assessment | Moving parts and the falling-package area should be protected against unintended access during operation. | Confirm the presence of physical guards, access-door interlocks, safe restart behavior, and prevention of automatic operation when a guard is open. | Safety-function test record, risk assessment, wiring or safety-circuit documentation, and an on-site acceptance test. |
| Emergency Stop and Safe Recovery | Applicable machinery-safety requirements | The emergency-stop function should bring hazardous motion to a safe state and should not automatically restart the equipment when reset. | Test emergency-stop locations, reset behavior, power-loss recovery, manual recovery from an interrupted cycle, and protection against unexpected restart. | Documented emergency-stop test, functional safety checklist, and operator training record. |
| Electrical and Pneumatic Safety | Local electrical regulations and site utility requirements | The machine must match the available power supply, compressed-air pressure, grounding method, and environmental conditions at the installation site. | Verify voltage and frequency, rated current, air-pressure range, air-quality requirements, protection against leakage, and accessible isolation points. | Electrical schematic, pneumatic diagram, nameplate information, insulation or grounding test where applicable, and installation checklist. |
| Calibration and Maintenance | Laboratory calibration procedure and quality-management system | The equipment should have defined verification intervals for height measurement, release function, levelness, safety devices, and structural components. | Ask for calibration scope, recommended interval, service parts, lubrication points, preventive-maintenance tasks, and remote or local technical support. | Calibration certificate, maintenance manual, spare-parts list, service response terms, and a clear re-verification procedure after repair or relocation. |
| Installation and Operator Training | Supplier installation procedure and customer safety rules | Installation quality can affect levelness, anchoring, drop height, impact behavior, and safe operation. | Confirm floor requirements, lifting method, installation time, commissioning scope, language of manuals, training content, and operator competency requirements. | Site-acceptance checklist, commissioning report, training attendance record, and signed handover documentation. |
| Supplier Selection Score | Customer-defined weighting model | A practical comparison should score compliance, measurement control, safety, serviceability, documentation, delivery, and total cost rather than purchase price alone. | Use a weighted scorecard and require the same technical evidence from every shortlisted supplier. Exclude any machine that fails a mandatory safety or method-compatibility requirement. | Completed technical questionnaire, quotation comparison, risk review, factory-acceptance report, and final site-acceptance report. |
