Visual similarity does not prove that bulk geosynthetics meet project requirements. Written values and agreed test methods remain the primary acceptance basis; a sealed sample supports checks of appearance, structure and labelling.
Define what the sample approves
Record the sample ID, date, product grade and the characteristics being approved. Do not let an untested hand sample override the project specification.
Control production changes
Require notification when resin source, formulation, construction or key process settings change in a way that may affect declared performance.
Inspect bulk supply by lot
Use representative lot sampling and keep roll IDs linked to test results. Compare dimensions, physical properties and identification against the approved technical schedule.
Project action list
What the procurement or project team should do next
Sign and date retained reference samples
Attach the final technical schedule to the order
Define lot size and sampling frequency
Agree the process for deviations before production
