Crash rated bollards are certified to withstand vehicle impacts according to standards such as ASTM F2656 and PAS 68, which specify the speed of impact and the allowable penetration distance after impact. These standards specify the speed of impact, the weight of the vehicle, and the permissible penetration distance after impact, and certifications such as K-ratings and M-ratings are used to classify bollards based on their performance in testing.
Key standards and ratings(International)
ASTM F2656:
This standard is the benchmark for high-speed crash testing in the United States. The test consists of vehicles of different weights (e.g., a 15,000 lb. truck or a 5,000 lb. car) striking a bollard at different speeds (30, 40, or 50 mph).
PAS 68:
British Standard for assessing the ability of vehicle security barriers, including bollards, to stop a 7.5-ton vehicle traveling at 30 mph.
IWA 14-1:
An international standard based on PAS 68 and incorporating elements of the American standard.
K-ratings (deprecated):
These ratings were originally developed by the U.S. Department of State to classify bollards based on the distance a 15,000-pound vehicle would travel past the bollard upon impact. Common classifications are K4 (30 mph), K8 (40 mph), and K12 (50 mph).
M-ratings:
These levels are governed by ASTM and are used in conjunction with F2656. They indicate the speed of the striking vehicle (e.g., M30, M40, M50) and the penetration level (P1, P2, P3, etc.), which indicates the depth of penetration of the vehicle through the bollard.
ASTM F3016:
This standard focuses on low-speed impacts (10, 20, or 30 mph) and is commonly used to protect bollards in pedestrian areas and storefronts.
Key standards and ratings(Chinese)
GA/T1343-2016:
It is set by China Public Security Department. This standard rating is categorized as A1, A2, A3, B1, B2, B3, C1, C2, C3, D1, D2, D3, E1, E2, E3.
