ASA long-term outdoor performance tracking missing
Fenómeno do problema
ASA outdoor products have performance complaints after several years, but lack of service period data supports analysis and improvement, and similar product risks cannot be assessed.
Análise das causas
Outdoor aging is a multi-year accumulation process; lack of systematic tracking makes failure data unable to be traced back to material batch and process; the correspondence between accelerated aging and real outdoor data is not established.
Solução
①Establish outdoor service tracking files for key products; ②retain same-batch samples for periodic re-test comparison; ③correlation modeling of accelerated aging and natural aging data; ④failed part recovery analysis improves the database.
Conclusão principal
The quality management of ASA outdoor products extends to the service period; retained sample re-testing is the lowest-cost tracking means; data assets determine long-term competitiveness.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
