Test drafts of at least four times the minimum registered volume are required for which type of device?

In measurement verification, accuracy improves when you test using a volume large enough to smooth out small errors that happen at slow flow. Slow-flow devices deliver small amounts over time, so using a test draft that is at least four times the minimum registered volume helps ensure the reading reflects true performance rather than transient effects like initial surge, residual air, or slight compression. This larger draft provides a stable, representative sample of the device’s behavior, making it easier to detect any deviation from the expected output. Other device types—those that operate more quickly or in different contexts—don’t rely on this four-times rule because their readings aren’t as sensitive to small-volume errors. Therefore, the requirement for a four-times minimum volume draft is specifically tied to slow-flow devices.
