ZASP’s K4 Security Fence — product reference Milita HB-FW301 Low Wall with Fence — has achieved an ISO 22343-1:2023 performance rating of V/7200[N2A]/48/90:0.0/6.9 in a full-scale vehicle impact test conducted by HORIBA MIRA. In plain terms: a 7,200 kg vehicle struck the assembly at 48 km/h and 90 degrees, and the vehicle did not pass the barrier line. Penetration was measured at 0.0 metres.

Reading the rating
The ISO 22343-1 string is compact by design, and every element matters. V identifies a vehicle security barrier. 7200 is the mass of the test vehicle in kilograms; [N2A] is its vehicle class. 48 is the impact speed in km/h and 90 the impact angle in degrees. After the colon, 0.0 is vehicle penetration in metres and 6.9 is the distance travelled by major debris.
For a specifier, the two numbers after the colon are the ones that decide whether a perimeter works. Penetration of 0.0 m means the vehicle stopped at the barrier line — the P1 penetration class, the highest performance level. The 6.9 m debris figure describes how far major fragments were carried; it is the kind of detail that matters when the protected asset sits close behind the fence line.
A fence is only as strong as the assembly beneath it. This result describes the system a site actually installs — wall, fence and foundation together.
Why testing the whole assembly matters
Perimeter products are often tested as isolated components: a post in a rig, a panel on a frame. Real sites do not work that way. A fence sits on a wall, the wall sits on a foundation, and the weak point is rarely where the catalogue drawing suggests. The HB-FW301 was tested as a complete low wall and fence assembly, so the published rating describes the installed system rather than an idealised component.
That distinction has practical consequences for long perimeters. Around substations, utilities, transport corridors, government campuses and data centres, it is rarely feasible to ring a two-kilometre boundary with bollards. A tested wall-and-fence line delivers continuous, rated protection without turning the site into a fortress — and gives security consultants a documented basis for specification instead of an assumption.
Where the K4 fence fits
- Critical infrastructure and utility substations with long boundary lines
- Transport, logistics and aviation landside perimeters
- Government, defence and embassy campuses
- Data centres and industrial sites requiring standoff and debris control
- Public spaces that need discreet, continuous vehicle protection
Available for specification
The Milita HB-FW301 is available to specifiers now. ZASP’s engineering team supports foundation design, site adaptation and installation planning, because a rated assembly is only rated when it is built as tested. The Memorandum of Performance and technical documentation are available to security consultants, integrators and approved partners on request.

FAQ
What does the rating V/7200[N2A]/48/90:0.0/6.9 mean?
It records a vehicle security barrier (V) tested with a 7,200 kg N2A-class vehicle at 48 km/h and a 90-degree impact angle, with 0.0 m of vehicle penetration and major debris travelling 6.9 m.
What is the P1 penetration class?
P1 is the highest penetration performance class: the test vehicle does not pass the barrier line. In this test, vehicle penetration was measured at 0.0 m.
What product was tested?
The ZASP Milita HB-FW301 Low Wall with Fence — a reinforced concrete low wall with an integrated security fence, tested as a complete assembly at HORIBA MIRA on 5 November 2026.
Where can I get the test documentation?
Specifiers, security consultants and approved partners can request the Memorandum of Performance and installation details from ZASP.
