F.10.3.1 Walls
a. Construction of Internal walls (vertical or horizontal) separating cells and/or segments must meet F.10.2.2
b. Internal vertical walls separating cells and/or segments must have minimum height of the full height of the Accumulator Segments
c. Fastened connections between the floor and any vertical wall of each Section must have minimum of two fasteners.
d. Removable horizontal interior walls must be fastened with a minimum of one fastener for each external vertical wall per section.
Folding or bending plate material to create flanges or to eliminate joints between walls is recommended.
F.10.3.2 Sections
a. Internal vertical walls divide the Accumulator Container into “Sections”
b. A maximum of 12 kg is allowed in any Section
c. Fastened connections between vertical walls around Sections containing 8kg or less must have a minimum of two fasteners
d. Fastened connections between vertical walls around sections containing between 8 kg and 12 kg must have a minimum of three fasteners
Example: An Accumulator Container with 2 internal walls has 3 Sections. Each Section contains less than 8 kg. Therefore 18 floor to wall joints are required in total with minimum two fasteners per joint.
F.10.3.3 If segments are arranged vertically above other segments, each layer of segments must have a load path to the Chassis attachments that does not pass through another layer of segments
F.10.3.3 Cells and Segments
a. The cells and/or segments must be appropriately secured against moving inside the Container.
b. This mounting system design must withstand the following accelerations:
40 g in the longitudinal direction (forward/aft)
40 g in the lateral direction (left/right)
20 g in the vertical direction (up/down)
c. Calculations and/or tests proving these requirements are met must be included in the SES.
d. Any fasteners must be 6 mm or 1/4” minimum diameter
