ASTM F1249 – 13 – Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared .This paper introduces the efforts to develop a new drop test method for ECUs under high shock condition that reconciles expected PCB vibration observed in the myriad of different end-use applications that ECUs can experience. The test method attempts to replicate the PCB deflection and its inherent solder joint stress that have been shown by . The evaluation of the guided drop test was carried out with the Bruceton method, a staircase method based on the ‘Manual of Tests and Criteria’ from the ‘United Nations’. 15. Setup of the guided drop test. The tests were performed at the guided drop test stand at BAM Test Site Technical Safety.
In conclusion, the drop-tower test methodology has inherent limitations when it comes to the evaluation of blast mitigation seats.

Drop test methods compared in this work are conducted with the set up depicted in Fig. 1. The PCB is mounted with the products facing downwards, onto four fixing poles on a drop table. The drop table falls down along the guiding rods and hits the striking surface. The impact is transferred to the test board via the fixing poles. The drop-weight test seems to be the most widely used, practical, and cost-effective approach among the numerous test methods [19]. Fig. 1 depicts the drop weight testing device designed and used by the researchers. This test offers a qualitative assessment of the energy absorbed by the specimen, determined by counting the number of blows .
Test Method for Drop Test of Loaded Containers by Free Fall. The ability to verify if a package system is sufficient to protect the inner contents during a free fall drop is paramount when confirming a package design. Based on the results, modifications to the design can be made to meet goals. This test method may be combined with other .upper-body injuries during mine blast events. A drop tower is one of the common low-cost methods of testing an energy-absorbing seat to determine the vehicle acceleration and associated level of blast that it can protect against. However, the lack of a standard drop tower test procedure for mine blast purposes means that different facilities Fig. 3 (a) shows the schematics of the JEDEC drop test performed in the present work. In this experiment, the drop test apparatus is Lansmont Model 23-D drop tester and test board is mounted on the drop table with component facing down, as shown in Figure(b).
