Meaning
Quality control limits that define the maximum allowable statistical deviation in electrochemical performance or physical dimensions before an entire production lot is disqualified. Sourcing contracts rely on the batch rejection threshold to prevent the delivery of cells with high variance that would undermine pack uniformity. This metric operates at the boundary where individual cell anomalies translate into systemic risk, halting the transfer of ownership of the material when failures exceed the allowed percentage.
Quality Control
Quality monitoring at the factory gate utilizes specific statistical tools to identify systemic manufacturing defects. Sourcing agreements utilize the batch rejection threshold to ensure that a seller cannot deliver a batch containing outlier cells. When testing reveals that the rate of deviation exceeds this designated parameter, the entire consignment is turned back.
Procurement Action
Financial exposure is directly linked to the point at which a buyer has the legal right to cancel an order. If a delivery violates the batch rejection threshold, the purchasing entity is protected from paying for substandard inventory. This ensures suppliers maintain rigorous factory floor calibration.
Industrial Limit
Testing protocols define the scope of these quality boundaries during the initial supply contract negotiation. The rule stops applying once the cells are welded into modules. At that stage, subpack variance becomes the primary diagnostic focus.
