slagingspercentage

Slagingspercentage, literally “discard percentage” in Dutch, is a measure of the proportion of items, observations, or data points that fail to meet defined criteria in a given inspection or test. It is commonly used in quality control to quantify how much of a production lot is rejected, and it is the complement of the yield percentage.

Calculation: slagingspercentage = (number rejected / total inspected) × 100. Example: In a batch of 5,000 units, 120 fail the required spec; slagingspercentage = (120/5000) × 100 = 2.4%.

Applications: It is used in manufacturing to assess process performance, in logistics for screening shipments, and in data handling or auditing to report non-conforming observations. It may also be tracked over time to monitor improvements.

Related terms: Yield (100% – slagingspercentage) and scrap rate or rejection rate (these phrases may vary by industry). The acceptance rate is the complementary metric (percentage accepted).

Factors: Criteria stringency, sampling method, batch variability, measurement error, and process changes influence the slagingspercentage. Larger, well-defined samples generally produce more reliable estimates.

Interpretation and use: A rising slagingspercentage indicates deteriorating quality or stricter criteria, while a declining rate suggests process improvement. Teams use trend analysis, root-cause analysis, and corrective actions to reduce it.

Limitations: The accuracy depends on sampling design and criteria stability; cross-line comparisons require harmonized definitions. Data should be contextualized with sample size and batch information.
