Outreach – Improving Awarenessof SAE J3043
Adoption of SAE J3043How Can the New England Council Members Help? Provide me with your contact information and I will sendyou an electronic version of FAQ handout Email any comments to [email protected] Distribute the FAQ one page enclosure to EMS providerswithin your state Make a decision to adopt a bumper-to-bumper standardthat includes SAE J3043

Cabinet Dynamic Testing – SAE J3058SAE J3058: Ready for AMD Member Review in Fall 2015Basic Testing ParametersManufacturer to determine cabinetloading capacity Utilized both front and sideimpact pulses Weights placed 4 inches fromeach door face Have now tested more than 30cabinets from 9 manufacturers Weights were directed at doorsurfaces and cabinets ends
Cabinet Contents Can Be A Hazard Too!Post crash(rollover)equipment andgurney positionsdrasticallychanged
Cabinet Dynamic Testing:4” behind door face

Modular Body Structural Integrity: TestMethodologySAE J3057: Ready for AMD Member Review in Fall 2015Key Elements in 2 PhaseRecommended Practice Phase 1 is a dynamic testwhere patient compartment isimpacted by 28,000 ft-lbf Phase 2 is a quasi-statictest evaluating side wall androof strength by loadingdamaged body at 2.5 x curbweight Doors must open after eachtest
Patient Compartment Integrity – SAE J3057Phase 1: Slowed Video ClipCart weight 14,170 lbs. with Impact Velocity of 7.69 mph
Phases 2 and 3:Quasi-Static Load on Side and RoofApplied Load Equals 2.5 timesGVWR first on one side thenvehicle rolled and load appliedto roof again all using the samepreviously impacted modularbody
Sub-Floor Structural Integrity:Test MethodologySAE J3102: Ready for AMD Member Review in Fall 2015Key Elements in thisRecommended Practice Testing can be completedstatically or dynamically Testing must be completedfor front, side, and rearloading Validates design for bothmodular body and van stylebodies
Sub-Floor Structural Integrity – SAE J3102 A rigid test device was used to pass loading into floorsub structure Loading in the frontal plane exceeded 18,000 lbs. Current AMD 004 Standard only requires 2,200 lb. pull
