What should be included in FAT and SAT acceptance for an industrial shot blasting line?

FAT and SAT Acceptance for an Industrial Shot Blasting Line — prevent delivery disputes and production downtime

Ambiguous acceptance criteria lead to delivery delays, rework, and warranty disputes.  Production launch stalls when mechanical defects, PLC alarms, or dust exceedances appear.  Contract-ready FAT and SAT checklists that tie Manufacturer and Supplier responsibilities to measurable tests and Customizable acceptance limits.

Acceptance must be evidence-based — documented mechanical inspection, trial workpieces, throughput verification, dust emission limits, PLC/alarm validation, spare parts and operator training sign-off; our company provides OEM/ODM-ready templates and Supplier validation workflows.

Mechanical Inspection: contract-ready criteria

• Scope: weld quality, alignment, bearing play, protective guards, and conveyor tracking.
• Measurements: dimensional checks with tolerances, runout <0.1 mm on wheel shafts, conveyor flatness and tension limits.
• Documentation: Manufacturer-signed inspection report, photos, and serial numbers for critical components.
• Acceptance rule: pass when all measured items are within contract tolerances or have documented corrective action with deadlines.

Trial Workpieces and Surface Quality

Validate process performance with representative parts:

1. Supply trial workpieces from production batch or agreed samples; include geometry and coating targets.
2. Run predefined cycles: three passes per sample at nominated wheel speed and conveyor speed.
3. Acceptance criteria: surface cleanliness grade (e.g., Sa2.5), anchor profile within supplier tolerance, no visible damage or distortion.
4. Record QA records: measurement method, operator, instrument calibration. Link failures to reblast triggers and corrective actions.

Throughput Test and Performance Validation

• Test sequence: ramp to nominal conveyor speed and run continuous operation for a full shift or agreed period.
• Metrics to record: pieces/hour, downtime events, abrasive consumption rate (kg/hr), energy draw at wheel motor.
• Acceptance: effective throughput ≥ contracted value after subtracting planned breaks and minor adjustments; document variance tolerance.

Dust Emission, Environmental and Safety Checks

• Dust emission: measure particulate concentration at extraction outlets and ambient points; compare to agreed mg/m3 limits and local regulations.
• Filter performance: verify pulse-jet or cartridge efficiency and replacement intervals as per Manufacturer data.
• Safety: emergency stops, interlocks, guard integrity, and signage checked and documented.
• Acceptance: emissions and safety items must meet regulatory and contract thresholds or be resolved before SAT sign-off.

Controls, PLC Alarms and HMI Verification

1. PLC logic: validate all alarm scenarios, interlocks, and automatic shutdowns using simulated faults and live tests.
2. HMI: confirm operator screens, alarm descriptions, and bilingual prompts where required.
3. Data logging: ensure event logs, batch IDs, and QA records are stored and exportable for traceability.
4. Acceptance: all critical alarms must trigger correct actions and be logged; Manufacturer to supply ladder logic version and change history.

Spare Parts, Operator Training and Punch List

• Spare parts: Supplier must provide a verified list with part numbers, minimum spares on site, lead times, and Consumable (abrasive/filter) recommendations.
• Training: operator and maintenance training completion certificates required; training materials must be Customizable for site SOPs.
• Punch list: compile open items during FAT/SAT with owners, remediation deadlines, and sign-off criteria; link to OEM/ODM warranty obligations.

Adopt these contract-ready FAT/SAT criteria, request our Supplier/OEM templates, and schedule joint FAT with Manufacturer representatives to secure on-time commissioning and warranty protection.
