ECCN 8B001
NSATWater Tunnels Designed to Have a Background Noise of Less Than 100 dB (Reference 1 µPa, 1 Hz) Within the Frequency Range Exceeding 0 Hz But Not Exceeding to 500 Hz and Designed for Measuring Acoustic Fields Generated by a Hydro-Flow Around Propulsion System Models.
What This ECCN Covers
ECCN 8B001 controls water tunnels designed to have a background noise of less than 100 dB (reference 1 µPa, 1 Hz) in the frequency range covered by the entry. These very quiet hydrodynamic test facilities support propeller and hull design and quieting research, so they are controlled for National Security and Anti-Terrorism reasons.
Who needs to check this?
Operators and builders of low-noise water tunnels and hydrodynamic test facilities, and naval-architecture and propulsion research labs.
Compliance tip
Control turns on the low background-noise threshold in the entry — ordinary cavitation tunnels may fall outside. With NS among the reasons, verify the Country Chart and screen for naval end uses before relying on a license exception.
Control Reasons
Items controlled for national security reasons under multilateral export control regimes.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
