How long should a packaging machine run to demonstrate stable output?
• Run continuously ≥8 hours, log cycle time every 30 min; stable if fluctuation ≤±5%.
• Full line must run 3 shifts (24 hours) with cumulative output compliance ≥98% and no downtime.
• Test must include film/roll changeover; rated speed recovered within 10 min after changeover.
• Judge by OEE: stable output requires OEE ≥85% during continuous run.
• Defect rate must be ≤0.5% per 10,000 packs; otherwise output is unstable and needs correction.
