Certified Design against Shipped Batch and the Gap Between
Closing the gap between certified designs and shipped batches demands rigorous incoming statistical acceptance sampling, teardowns, and strict contract limits.
Non-Conformance Quarantine
Meaning
Material management procedures prevent the accidental use of defective or unverified components in production lines. When a quality failure is detected, non-conformance quarantine isolates the suspect materials in a designated, secure area to prevent further processing or shipment. This control mechanism is a standard component of automotive battery manufacturing standards.
Isolation Protocol
The process begins immediately after an automated inspection system or a quality auditor flags a batch of cells or raw materials. During a non-conformance quarantine, the physical material is marked with a distinctive red tag and moved to a locked storage area. Simultaneously, the enterprise resource planning software locks the corresponding inventory lot to prevent any electronic transactions or releases.
Inspection Flow
While the material is isolated, a cross-functional quality team conducts a root cause analysis to determine the extent of the issue. If the deviation is found to be minor, the material may be released after undergoing re-work or being approved under a customer deviation request. If the issues are severe, the materials are slated for disposal or recycling.
Inventory Audit
Logistics managers audit these locked zones weekly to ensure that no unauthorized material movements occur. Keeping a clear audit trail of these transactions is necessary for regulatory compliance and safety certifications.
