aggregate testing

Aggregate testing involves combining multiple individual samples—such as soil, materials, or products—into one pooled sample for analysis. Instead of testing each sample separately, this method assesses the group collectively, helping to quickly identify if any portion has an issue or meets certain standards. If the aggregate test passes, all samples are considered acceptable; if it fails, additional testing on individual samples may be needed. This approach saves time and resources, especially in large-scale inspections like manufacturing quality control or construction material evaluation.
