Non-crash-rated bollards, on the other hand, are not designed to withstand high-speed impacts. They serve more as visual cues and physical guides for traffic.

These bollards are often used in low-risk areas. They can be found in parking lots, bike lanes, or pedestrian walkways.

While they can deter accidental vehicle incursions, they may not stop a high-speed vehicle. Their primary role is to guide traffic and delineate spaces.

So, while non-crash-rated bollards play a crucial role in urban planning, they offer less protection than their crash-rated counterparts.

Standards and Ratings: PAS68 and Beyond

When it comes to crash-rated bollards, not all are created equal. Their strength and resistance are determined by specific standards and ratings.

The most common standard is the PAS68. This is a UK standard for vehicle security barriers. It tests the bollards’ ability to stop a 7.5-ton vehicle traveling at 30 mph.

There’s also the K-rating, a US standard. It tests the bollards’ ability to stop a 15,000-pound vehicle at various speeds. The ratings are K4 (30 mph), K8 (40 mph), and K12 (50 mph).

• PAS68: Stops a 7.5-ton vehicle at 30 mph
• K4: Stops a 15,000-pound vehicle at 30 mph
• K8: Stops a 15,000-pound vehicle at 40 mph
• K12: Stops a 15,000-pound vehicle at 50 mph

These standards ensure that the bollards can withstand high-speed impacts and provide the necessary level of protection.

Deciphering PAS68, K-Ratings, and HVM Bollards

Understanding these ratings is crucial in selecting the right bollards for your urban planning project. The PAS68 and K-ratings indicate the bollards’ crash resistance.

HVM, or Hostile Vehicle Mitigation, is another term you might come across. This refers to measures taken to protect against vehicle-based threats. Crash-rated bollards are a key component of HVM strategies.

So, when you see a bollard with a PAS68 or K-rating, you know it’s designed to stop a vehicle. And if it’s part of an HVM strategy, it’s there to protect against hostile vehicle attacks.

In essence, these ratings and terms help you understand the level of protection a bollard can provide.

Testing and Certification of Crash-Rated Bollards

Crash-rated bollards undergo rigorous testing to earn their ratings. They are subjected to simulated vehicle impacts at various speeds.

The tests measure the bollards’ ability to stop a vehicle and prevent it from penetrating a protected area. The bollards must remain functional after the impact to earn their rating.

These tests are conducted by independent bodies to ensure impartiality. The results are then used to certify the bollards as crash-rated.

This testing and certification process ensures that crash-rated bollards can deliver on their promise of protection. It gives urban planners the confidence to use them in their designs.
