Open the registerHow do I read an ISO 22343-1 performance rating?
The NPSA guidance gives the form as barrier type, test type, mass, vehicle class, speed, angle, penetration and debris, for example Bollard V / 7200 [N3C] / 48 / 90 : 2.6 / 5.0. The test type is V for vehicle impact, the mass is in kilograms, the speed is in km/h, the angle is in degrees, and the two figures after the colon are the penetration and debris distances in metres.
Last updated: . Written from the public record and the published base standard. Not legal advice; does not certify.
The parts before the colon
The barrier type names the article. V is the vehicle impact test. 7200 is the total test mass in kilograms. N3C is the UNECE vehicle class. 48 is the measured impact speed in km/h. 90 is the horizontal impact angle in degrees.
The parts after the colon
The first figure is the vehicle penetration distance in metres, measured from the VSB datum line. The second is the major debris distance in metres, to the furthest piece of at least 2 kg. A string without the debris figure has lost a condition.
Why the class matters
The class fixes the body shape and the Table 2 test mass. A 7 200 kg N2A, N2B and N3C share a mass but not a body. A rating for one is not a rating for another, and a mass alone does not identify the class.
How to store it
Keep the original string exactly as issued, then decode it into a table with one column per part and a link to the report. Do not shorten it in a specification. Do not convert an IWA 14-1 or PAS 68 string into this form.

Questions
What does the V mean?
V is the test type for a vehicle impact. The barrier type sits before it, so the string starts with the article and the test type together.
Is the penetration dynamic or static?
The standard takes the greater of the dynamic distance during the impact and the static distance after it. Ask the test house which figure is reported.
What is major debris?
A piece of the barrier, the vehicle or the ballast with a mass of at least 2 kg. The distance is measured to the furthest such piece.
