We are accredited as testing center in accordance with DIN EN ISO / IEC 17025 and registered as testing centre for dynamic overrun impact tests on tank containers and MEGCs (Multiple Element Gas Container) by Transport . This video was published by the Federal Railroad Administration and shows the difference a vehicle designed for crashworthiness and one which is not.the ‘Steel Guard’ set-up. The forklift is traveling at 5 miles/hour or 7.33 feet/second at initial impact with the guardrail. The forklift is driven in reverse so as not to puncture the rails with the forks and to better distribute the impact force between both rails. Test results: The impact stopping time is assumed to be one second.
The load must successfully complete rail impact testing. Once the test is successfully completed, the vehicle will be assigned a loading figure in the AAR’s OTLR manual. The loading figure is a graphic display with the info that’s required to properly load and secure that specific secondary load, necessary equipment and any additional . The wheel-rail impact load can reach up to 3–4 times the normal wheel load, with two peaks including a high-frequency impact force (P 1) and a mid-frequency or quasi-static impact force (P 2).To effectively monitor the wheel-rail impact, this study utilizes strain gauges adhered to bottom of iron plates of fastener to measure rail-seat force, and conducts indoor .Railway physical tests also include testing under extreme events, like derailment safety tests, rail crash tests or impact tests. Once tests are completed, rolling stock and component manufacturers can learn from the results of the tests and use them as a basis for the commissioning approval, for certification or to make necessary improvements. Impact Testing of Railcar Draft Systems. As part of the Association of American Railroad (AAR) Strategic Research Initiatives (SRI) program, MxV Rail conducted impact tests on six different railcar draft systems to characterize and evaluate their performance. The results showed that end-of-car cushioning (EOCC) units provided the most impact .

TECHNOLOGY PARTNER1.1 These test methods cover procedures to be followed in testing the performance of permanent metal railing systems (guard, stair, and ramp-rail systems) and rails (hand, wall, grab, and transfer rails) installed in and for agricultural, assembly, commercial, educational, industrial, institutional, recreational, and residential buildings.RAIL IMPACT TEST METHOD. The test load or vehicle will be secured to a flatcar. The equipment needed to perform the test will include the specimen (hammer) car, four empty railroad cars connected together to serve as the anvil, and a .
Hail impact testing helps protect life and property during storms. In other industries, hail impact testing protects roofs, automobiles, and crops and livestock from impact. Comprehensive hail testing for all applications. For safety and quality reasons, the hail impact testing program is an integral piece of product qualification programs . TOP-1-2-501, TEST OPERATIONS PROCEDURE: RAIL IMPACT TESTING (15-SEP-2008)., This TOP describes the procedure for conducting a rail impact test. The rail impact test is used to verify structural integrity of the test item and the adequacy of the tie-down system and tie-down procedures. This TOP is intended for vehicles and equipment that will be .
RAIL 7 ACT TEST PROCEDURES A. RAIL IMPACT TESTING: Rail impact testing was accomplished in compliance with previously approved and standardized testing procedures as shown on Page 111-3 and described as follows: 1. The 'Specimen Car' was scheduled to be impacted four times; three times at speeds of 4, 8, and 8 mph in one direction, and one time .

Single Passenger Rail Car Impact Test Volume I: Overview and Selected Results U. S. Department of Transportation Federal Railroad Administration Office of Research and Development Washington, D.C. 20590 DOT/FRA/ORD-00/02.1 DOT-VNTSC-FRA-00-01 Final Report March 2000 This document is available to the public through the National TechnicalTUV Sud Rail Impact Test. Our Flexitank went through a Crash Testat TUV Sud – Gorlitz. Germany in 2009. Filled Flexitanks were loaded into a container on a wagon and were impacted at various speeds similar to and routinely during the actual handling and transportation ranging from 5 km/h to 12 km/h.
TEST OPERATIONS PROCEDURE RAIL IMPACT
Rail Impact MIL-STD-810 Method 526 replicates railcar impact conditions to evaluate tie down systems and tie down procedures used in the transport of equipment. This test is not a laboratory test but is performed actual rail cars involved in the impacts during coupling. It normally involves car impact testing at speeds under 8 mph (12.9 km/h).The rail impact test is used to verify structural integrity of the test item and the adequacy of the tie-down system and tie-down procedures This TOP is intended for vehicles and equipment that will be transported by rail; to determine the effect of normal railroad car impacts that occur during rail shipment over the full life span of the test .
CEM system individually dynamically tested by means of a rail in managing the load path, absorbing impact energy, and inhibiting override and lateral bucklingin a train-to-train collision scenario. The target impact speed was 21 mph. The actual speed of the test was 24.3 mph. The impact test resulted in the CEM system workingThe rail impact test was conducted with the loaded vehicles secured directly to the railcar. The vehicles were secured to the railcar in accordance with MTMCTEA Pamphlet 55-19 "Tie-down Handbook for Rail Movements." The S-280 Tie-down Kit was used to secure the S-280 Shelter to the vehicle. A. RAIL IMPACT TEST METHOD.
Wheel–rail impact load can be three to four times the normal wheel load and can severely affect the safety and service life of wheels and tracks, so it is an important topic in the railway transport field [1]. . Wheel–rail force testing methods mostly use a static load to verify the accuracy of the test results, but when such tests are .
