The system recently passed impact tests, where it prevented a 7,200kg lorry travelling at 32kph from penetrating less than five metres.

As a German, I'm kinda confused how that "truck" is called a "lorry". I think in Germany it would be classified as a PKW (Personal vehicle) [0], as opposed to an LKW (Cargo vehicle) [1].

I wonder how such a barrier would fare against an LKW with heavy cargo?

Doesn't "preventing from penetrating less" mean it allowed it to penetrate more?

I would read it as equivalent to "forced it to penetrate at least five meters, if it penetrates at all".

If I prevent you from entering a password shorter than 8 characters that means you can either not enter a password or one with at least 8 characters. This is exactly analogous.

According to the technical specifications, the security rating is:

    IWA 14: V/2,500(N1G)/48/90:4.5
    IWA 14: V/7,200(N3C)/32/90:4.8
I interpret that like this:

2,500 kg vehicle traveling at 48 km/h penetrates 4.5 metres

7,200 kg vehicle traveling at 32 km/h penetrates 4.8 metres

The article describes one part of the specification and links to a video demonstrating the other part.

Yup. The pickup truck shown in the video most certainly does not mass 7,200 kg.

Exactly, as the video title is "2,500 kg @ 30 mph"

In the EU a B-class driver's license allows you to drive anything up to 3500kg. Exceeding that you need at least a C1 class license (truck/lorry license) for up to 7500kg. Above that you need a full C class license.

So 7200kg is definitely a truck/lorry.

According to the title of your video, it shows a different test scenario with only a 2500kg vehicle but higher speed.
Re:Those odd-looking security barriers by meheleventyone on Wednesday November 06, 2019 @12:21PM (#21464658)
That video says the truck weighs 2500kg so I presume the 7200kg lorry is a different thing.
Re:Those odd-looking security barriers by gnabgib on Wednesday November 06, 2019 @12:30PM (#21464771)
Agreed, while the video is impressive (presumably in a full install, the rack has stronger connection to the ground).. it does say 2500kg at 30mph(~50kph).. not the 7200kg at 32kph(~20mph) the article mentions

As a Brit, I highly doubt that Ian sincerely believes that vehicle is a "lorry" - having said that, pickup trucks are not common in the UK so he might simply be unfamiliar with them and thought "lorry" was the accepted term.
Re:Those odd-looking security barriers by OJFord on Wednesday November 06, 2019 @02:31PM (#21466156)
I'd be very surprised if any British person (Americans I believe don't call any vehicle a 'lorry') would call that a lorry. Lorries are the container + cab vehicles, or fixed backs of similar shape and size.

I suspect the author wrote that without seeing the footage, perhaps reading 'truck' and assuming it was a lorry being described by someone who wouldn't use the word, as above.

The link or text must be wrong. From the link:

> Surface Guard Impact Test: IWA 14 - 2,500 kg @ 30 mph

So it's not a "7,200kg lorry". It's a 2,500 kg extended cab pickup.

Top picture at http://notesfromthedrivingseat.blogspot.com/2011/04/vehicle-... (discussing category C1 medium goods vehicle driving licences) is a 7.5 ton lorry. I would expect a 7.2 ton goods vehicle to be similarly more lorry than van.
Re:Those odd-looking security barriers by netsharc on Wednesday November 06, 2019 @04:09PM (#21467316)
But that video is of a 2500 kg "truck", so it really is a PKW (it's under 3500kg). Something weighing 7200kg is definitely a lorry.
Re:Those odd-looking security barriers by mcguire on Wednesday November 06, 2019 @12:52PM (#21464999)
That looks like what an American would call a "full-size pickup", which do not weigh 7,200kg (~16,000lbs).
Re:Those odd-looking security barriers by throwaway0xb on Wednesday November 06, 2019 @01:00PM (#21465072)
Looks like a compact sized pickup truck, to me.
Re:Those odd-looking security barriers by zaarn on Wednesday November 06, 2019 @12:22PM (#21464672)
A 7.2ton vehicle would definitely be called a LKW (Llkw or Mlkw).
