Current condition
Identify pack formats, product and tare variation, actual sustained/peak rate, pitch and transfers. Record the intended weight decision, acceptance window and how known challenge weights are established.
Dynamic production weighing
High Speed Checkweighing: Challenge-Test and Reject Checklist
Agree high-speed checkweighing challenge packs, expected weight decisions, actual rate and pitch, reject tracking, physical removal confirmation and records for unresolved outcomes.
Agree identified acceptable, known-fault and marginal challenge packs and expected weighing decisions before testing. Run the representative formats at the intended rate, pitch and transfer conditions. Record each decision and whether the correct pack was physically removed and confirmed, including consecutive rejects and relevant operating changes.
Connect the pack and spacing conditions to the complete weighing and reject process. An accepted trial does not establish untested accuracy, a maximum rate or legal compliance for every packed-goods duty.
On the production floor
Turn your production information into clearer decisions — High Speed Checkweighing
Plan high speed checkweighing around the smallest meaningful weight difference, normal product and tare variation, pack transfer, line speed, reject confirmation and traceable test evidence. Use this guide to resolve test packs, challenge method, records and production response before it limits the final system.

What to record
Test Packs, Challenge Method, Records and Production Response: condition, range and effect on your process
Realistic range
Include the least stable credible formats, product movement, gap variation, starts/stops and relevant vibration or conveyor transitions. State which formats or running conditions are not covered by the trial.
Effect on the system
Record the observed weight decisions, pack tracking, physical rejection and confirmation under those conditions. Agree the line response and owner for uncertain decisions, unconfirmed removal and unresolved trial limits.
Before you contact us
Five questions about test packs, challenge method, records and production response for your application
- Who can confirm this information?Identify production, quality and engineering owners for the pack/weight information, running conditions, challenge method and acceptance decision.
- How representative is the sample?Use identified production formats, normal product and tare variation and known acceptable, faulty and marginal weight examples. Retain the source and expected decision for each challenge pack.
- What is the difficult condition?Include unstable or moving contents, the intended rate and gap variation, transfer disturbance, starts/stops and consecutive rejects where relevant.
- How will you judge the result?Agree the trial method, repetitions and expected weight and removal results before running. Retain actual outcomes and conditions, discrepancies and required follow-up.
- What else must be coordinated?Agree transfers, controls, reject/removal confirmation, reject-bin conditions, records and production response, with responsibilities for unresolved cases.
Connected details
Review test packs, challenge method, records and production response as part of the complete system
Pack Weight, Stability, Spacing and Normal Tare Variation At the Required Rate
Record representative pack weights, normal product and tare variation and the required sustained and peak production pattern. Retain the pack format, stability and spacing conditions alongside each trial result.
Smallest Meaningful Weight Difference and Acceptance Window
Define the smallest weight difference that matters and the intended acceptance window. Compare known challenge packs with normal product and packaging variation before accepting a discrimination claim.
Pack Dimensions, Stability and Conveyor Presentation
Provide the pack dimensions and least stable credible formats. Observe product movement, pickup onto the weighing conveyor and downstream transfer under the intended running conditions.
Line Speed, Spacing, Vibration and Transfer Conditions
Record line rate, actual pack pitch, gap variation, starts/stops, accumulation and nearby vibration. Include acceleration, deceleration and conveyor transitions in the trial conditions rather than citing rate alone.
Reject Device, Removal Confirmation and Reject-Bin State
Keep the failed pack associated with its decision through the reject. Challenge physical removal and confirmation, consecutive rejects and relevant reject-bin conditions, with the required response agreed.
Test Packs, Challenge Method, Records and Production Response
Agree identified test packs, expected decisions, repetitions and records for the complete weighing and reject sequence. Retain actual outcomes, uncertain cases, conditions and responsible follow-up.
