IWA 14-1:2013 means an impact test standard that details a system for classifying the performance of vehicle safety barriers subjected to a single horizontal impact.

IWA 14-1:2013 is based on elements of two other major impact testing standards, PAS 68 and ASTM. This is the most common standard you'll find for HVM bollards, bollards and barriers to protect against hostile vehicles. IWA 14-1:2013 was designed to be considered the "global standard for impact testing" with contributions from the National Infrastructure Protection Center, British Standards Institute, the US Department of State and others.

The guide will provide you with a quick and easy example product rating with an explanation of each section so you can easily interpret the rating code in the future.

So, let's know more about IWA 14-1:2013 standard

IWA stands for International Workshop Agreement and is overseen by the International Organization for Standardization (ISO).

Unlike most documents controlled by ISO, IWA 14-1:2013 was developed outside of the usual committee system. This allowed key industry players to deal in an open work environment, which allowed them to shape the IWA standard. If you're viewing the code of the numbers and letters that create up the IWA Impact Test rating of 14 for the first time, it doesn't really make much sense, but once you understand what each section means, it becomes more straightforward.

For those of you who are familiar with PAS 68 or have read our manual on this British Impact Test Specification (sometimes called the standard), this code will be familiar to you. There are a few key differences though.

The best way to explain the IWA 14 rating is to break it down step by step. For this, we will use a series of three RB345-09-S anti-ram fixed bollards as an example.

Detailed explanation of each components of the rating

Test Method V/7200[N2B]/80/90:0.7 As with PAS 68, the IWA 14 rating starts with the type of test performed. In this case, it was a vehicle test. This means that a real car crashed into a blocker for product certification.
The difference between IWA 14-1 and PAS 68 is that vehicle testing is the only method used, while PAS 68 also allows pendulum and simulation tests.
Machine type V/7200[N2B]/80/90:0.7 As with PAS 68, the IWA 14 rating starts with the type of test performed. In this case, it was a vehicle test. This means that a real car crashed into a blocker for product certification.
The difference between IWA 14-1 and PAS 68 is that vehicle testing is the only method used, while PAS 68 also allows pendulum and simulation tests.
Speed test V/7200[N2B]/80/90:0.7 Next, you have a test speed, which indicates the speed in kilometers per hour (km / h) that the vehicle was traveling at for the test.
For the IWA 14, the impact speed can range from 16 to 112 km / h, although the most common speeds are 32 km / h (20 mph), 48 km / h (30 mph), 64 km / h (40 mph). h) and 80 km / h (50 mph).
In our example, the anti-ram fixed bollards, as you can see, were tested at 80 km / h (50 mph).

You may be asking - how do I know which rated product is right for me? It’s our opinion that in most cases the rating of the product you are looking for will be determined by doing a "dynamic vehicle assessment".
These assessments are usually carried out by a counterterrorism advisor or certified security consultant. The VDA will help identify the vehicle's threat and set the maximum attack speed.
Impact angle V/7200[N2B]/80/90:0.7 Additionally you have the angle at which the vehicle hits the product, usually 90 °, but sometimes you see 30 ° and 45 °. 30 ° and 45 ° test certificates are sometimes requested when installing products in low angle of attack scenarios such as bridge deck or fence testing.
You also need to be careful, as some products will be directional and may work at 45 ° but not 225 °.
Penetration V/7200[N2B]/80/90:0.7 The Penetration Depth Chart shows how far, in meters, the vehicles load has crossed the VSB baseline. The baseline is the point from which the vehicle penetration is measured. For IWA 14, this is the front of the product.
This is another difference between the IWA 14 and PAS 68, where penetration is measured by how far the load has traveled past the back surface of the product.

Our example shows a penetration of only 0.7 meters. The level of penetration that is considered acceptable may vary depending on the perimeter line in relation to the area that you want to protect.

Measuring of penetration

VSB Reference Point is front face of VSB.
IWA standard keeps track of flying debris from the front of the blocker (blue line). This is one of the parameters that distinguish the IWA from the other standards (PAS test, for example). The red line marks the point from which it is considered zero point when measuring the level of penetration of large debris.

IWA 14-1:2013 VS PAS68 VS ASTM: different from other standards

IWA 14-1:2013 rating does not include debris dispersal. Measurement of the main scattering of debris showed that after impact, debris weighing more than 25 kg penetrated the furthest.

This is part of the PAS 68 rating to help security engineers visualize the test. However, this has caused some confusion in the past and has therefore been removed from the IWA 14 standard.

According to ASTM, products must be installed in loosely cohesive compacted soil, while PAS 68 does not specify the type of soil for products tested under conditions that are suitable for use. The IWA 14, on the other hand, allows testing both in soil and on site.

 

Other standards

Presently that you're familiar with IWA 14-1:2013, you can memorise more about other impact test standards you may arrive across. Two other major standards that you'll arrive across are PAS 68 and ASTM. PAS 68, which has a lot in common with IWA 14-1:2013, is a British test specification for reducing the danger of hostile vehicles and is fully explained in our detailed guide.

ASTM F2656 / F2656M is the US standard for crash testing safety products. The American Society for Testing Materials plays the same role as BSI. You may also arrive across DOS (Dept of State), which is an elderly US standard that's presently been superseded by ASTM. We'll see at this standard in a future guide.

The latest standard you can also discover is the CWA, which is a European agreement that combines the elements of PAS 68 and PAS 68. PAS 68 is a specification for the exact installation of impact certified products.
