Simplified Measurement Verification Practice Test

When equipped with a discharge valve, a rigid measure of liquid volume shall be susceptible of?

Sealing the valve closes with a security seal

The main idea is tamper-evident security for a liquid-measuring device. When a rigid measure has a discharge valve, it should be possible to seal the valve with a security seal after closing it. This ensures the device’s contents and indicated volume remain protected between verifications; opening the valve would break the seal and signal tampering, preserving the integrity of the measurement.

The other ideas focus on how the device drains or is calibrated, which are separate concerns from preserving measurement integrity through sealing. So sealing the discharge valve with a security seal is the appropriate requirement.
