Express courier. Direct.
Also overnight.
x25pronto Switzerland takes goods direct to the destination. Small loads go by car. Larger loads go by van or Van XL. Direct, express and overnight trips run Monday to Sunday when a slot is free. Free times are shown in the booking calendar. This keeps the plan clear.
Packaging tests: drop and vibration tests for small shipments
A practical guide to simple drop and vibration procedures for small, well-packed shipments. Includes test setups, measurement logs and limit values for businesses in Zurich, Geneva or Basel.
Quick answer
Drop and vibration tests show whether a small shipment survives realistic handling during courier transport. Run defined drop scenarios and continuous vibration loads with basic test rigs. Record shock peaks, observed damage and sensor data in a test report. Use clear limit values by sensitivity class to decide packaging and reduce claims.
Why these tests matter for courier transport
Courier routes in Switzerland combine short runs, multiple handlings and quick transfers between cities such as Zurich, Bern or Basel. Small parcels face shocks and vibrations. Standardized drop and vibration tests reveal weak points. You can compare packaging options and lower transport damage.
Simple drop tests
Purpose: Check if contents are damaged after a defined fall. Setup: Mark realistic drop heights (e.g. 0.5 m, 1 m, 1.5 m). Use a flat clean surface and drop the packaged item in a controlled way. Test variants: corner, edge and face. For small shipments 0.5–1.5 m often represent real scenarios. After each drop check external damage, test the product function and log acceleration peaks with a basic data logger or accelerometer.
Practical vibration tests
Purpose: Reproduce continuous vibration during transport and handling. Simple setup: place the shipment on a vibrating plate or a small shaker. Frequency range: 5–200 Hz covers many vehicle vibrations. Test duration: 30–120 minutes depending on sensitivity. Record visual changes, loosening of packing materials and functional failures. FFT-capable loggers help identify dominant frequencies.
What to include in a test report
A useful protocol includes: shipment data (dimensions, weight), packaging materials, sensitivity class, test type (drop/vibration), test parameters (height, frequency, duration), measured values (G-peaks, acceleration profiles), observations (damage, loosening) and conclusion. Add photos before and after and assign a damage category (none, minor, critical).
Limit values and sensitivity classes
Classify products as non-sensitive, moderately sensitive, very sensitive. Sample guidance: non-sensitive: drop 1.0 m, vibration 30–60 min; moderately sensitive: drop 0.5–1.0 m, vibration 60–90 min; very sensitive: drop 0.5 m, vibration 90–120 min plus internal foam. For electronics a common short-term shock threshold is below 50 g. Adjust values to your products and record the basis for decisions.
Practical tips and working with couriers
Test with representative packed samples, not only ideal prototypes. Train packing staff and keep standard test records for claims. Share relevant test results with your courier partner in Zurich or Geneva to improve handling expectations. Low-cost data loggers provide useful insight without high lab costs.
Frequently asked questions
Do I need special gear for drop tests?
Basic accelerometers or compact data loggers are often enough for qualification tests. For lab-accurate curves higher-spec devices help. Photos and functional checks complement sensor data.
Which frequencies should vibration tests cover?
A practical range for courier transport is 5–200 Hz. Low frequencies reflect vehicle movements, higher frequencies come from impacts and rattling.
How many repetitions are required?
Repeat each configuration at least three times for reproducible results. Re-test after any change in packaging or with new product types.
Will tests prevent all damages?
Tests reduce risk by revealing weaknesses. They do not replace correct internal packaging, cushioning and careful handling.
