In order to achieve this designation, Delta had to successfully test both lengths at the same crash rating. Both the 10’ and 16’ barriers passed the newer ASTM F2656-20 Standard with M50/P1 designation and achieved negative penetration.

The 10’ and 16’ DSC550 were both tested to the new ASTM F2656-20 standard which measures the penetration level from the leading edge of the barrier versus the back-side of the barrier like the previous standard. This can provide a difference of up to five additional feet (1.52 m.) and makes the negative penetration level even more impressive. Both barriers were operational after the force of the M50 impact. The barrier was able to raise and lower after impact with a slight deformation of the upper beam.

Shallow foundation

The DSC550 Open Frame barrier also features a shallow foundation of only 24 inches (61 cm). The DSC550 alleviates the concerns of interference with buried pipes, power lines and fiber optic communication lines in urban applications. The shallow foundation also reduces installation complexity, time, materials and corresponding costs. The DSC550 is perfect for high water table locations and areas with corrosive soils.

“Delta continues to showcase the strength and resilience of our barrier product line,” attests Greg Hamm, Delta Scientific Vice President, Sales & Marketing. “This test is just another example of how Delta’s engineering prowess continues to lead the industry over the last 49 years. If you purchase a Delta barrier you know you are getting the best product on the market with the highest quality components. Best of all, it’s made in the U.S.A. at our factory in Palmdale, California.”

Fast operation

The DSC550 provides an emergency fast operation of 1.5 seconds for electro-mechanical and 0.75 seconds for hydraulic operations. This allows a guard to quickly react to a perceived threat with the peace of mind knowing the barrier will deploy in a rapid manner under the most demanding scenarios. The DSC550 also provides intuitive touchscreen controls with data-logging and custom programming.
