Revision A (Dated 05/01/13) 13
III. Performance Criteria
The TrafFix Water-Wall shall be tested and pass all test requirements of Report NCHRP-350 as
listed:
- Test TL-1 Longitudinal Barrier 2000 kg [4500 lbs.] vehicles at speeds of 50 kph [31.2 mph]
- TL-2 Longitudinal Channelizing Device 820 kg [1808 lbs.] vehicles at speeds of 70 kph
[43.5 mph]
- TL-3 Barricade (Single Unit) 820 kg [1808 lbs.] vehicles at speeds of 100 kph [62.5 mph]
The TrafFix Water-Wall TL-1 test results, 6.4 m/s for occupant impact velocity and 3.9 g for
ridedown acceleration, demonstrating a non-gating, controlled penetration into the barrier device
when impacted at a high angle at the critical impact point.
Maximum dynamic deflection at point of impact shall not exceed 15.5 ft. [4.7 m] when impacted
at the design speed of TL-1 50 km/h (31.2 mph) utilizing the 2000 kg (4500 lbs.) vehicle.
The TrafFix Water-Wall shall be capable of preventing vehicle penetration, vaulting, under
riding, and shall bring the impacting vehicle to a controlled stop in the vicinity of the impact
area. For shallow angle impacts it shall redirect the vehicle, while undergoing controlled lateral
deflection.
Detached debris shall not show potential for penetrating the vehicle occupant compartment or
present a hazard to other traffic, pedestrians, or workers in a protected zone.
A vehicle impacting the TrafFix Water-Wall shall remain upright during and after the collision
though moderate roll, pitch, and yaw may occur.

The impacting vehicles intrusion into adjacent traffic lanes shall be minimized.
