Product Evaluation
Remagen defense products which employ the thin inertial blast wall technology of Remagen’s Blast and Ballistic Wall System (B2WS) have undergone laboratory testing by the Air Force Research Laboratory (AFRL) at the University of Missouri, Columbia as well as field explosive blast and terminal ballistics testing under supervision of Remagen engineering personnel. Much of this testing and evaluation was conducted in collaboration with Remagen’s sister company, Bastogne Manufacturing, LLC (BastogneBlastProtection.com). Remagen’s president, Jim Waller, is also Chief Engineer for Bastogne. The technology of the blast and ballistics resistant products is governed by International Traffic in Arms Regulations (ITAR). Therefore, performance of these products may not be disclosed to unqualified persons or entities and disclosure is strictly governed by Non-Disclosure Agreements. Unclassified reports on evaluation results are available upon written request to Remagen Corporation. Classified blast and ordnance resistance capabilities of Remagen’s expeditionary tactical shelters and bomb blast mitigation walls are available for military and government entities and contractors having appropriate security clearances.

Laboratory Evaluations
Laboratory evaluations of various models of the Blast and Ballistics Wall System (B2WS) give Remagen and its customers’ engineering personnel technical data necessary to determine the response of variable systems to explosive blasts at varying stand-off distances. The B2WS’s fundamental frequency and damping factor are necessary to calculate the B2WS’s dynamic response to blast pressures as a single degree of freedom (SDOF) system. High strain rate behavior of bonding adhesives is required to evaluate composite behavior of the B2WS in the inelastic response range. Results of laboratory evaluations are used to calculate blast time histories of the B2WS in accordance with “Structures to Resist the Effects of Accidental Explosions”, November 1990, Army TM5-1300, Navy NAVFAC P-397, Air Force AFR 88-22. B2WS are typically designed to resist blast pressures from specified explosive weapon yields at stand-off distances which result in pressures in ranges above those causing structural collapse and below those which are potentially lethal.

Terminal Ballistics Evaluations
RemagenSafeRooms engineers have tested numerous Thin Inertial Blast Wall (TIBW) designs to determine which configurations provide optimum terminal ballistics resistance to weight ratios for specific explosive charge weights and fragmentation and ballistic threats. Although laboratory testing to determine UL 752 and NIJ I-IV terminal ballistics ratings have not been conducted by Remagen, we have developed a broad range of Blast and Ballistics Wall Systems (B2WS) designs which will satisfy most ballistics requirements of customers with minimum areal density. In-house ballistics testing, conducted in accordance with MIL-STD-662F, was conducted to determine B2WS resistance to fragmentation from improvised explosive devices and small arms fire up to .50 cal. steel core (50 BMG, 660 grain FMJ, XM33C).

The proprietary technology of the B2WS is governed by International Traffic in Arms Regulations (ITAR). Therefore, performance of these products may not be disclosed to unqualified persons or entities and disclosure is strictly governed by Non-Disclosure Agreements. Where classified blast and ordnance resistance capabilities of Remagen’s expeditionary tactical shelters and blast- and ballistics-resistant walls have been conducted, these capabilities will be available for military and government entities and contractors having appropriate security clearances.
