F.8.6.1 Inside Primary Structure
All Non Crushable Objects (such as batteries, master cylinders, hydraulic reservoirs) inside the Primary Structure must have a minimum 25 mm clearance to the rear face of the Anti Intrusion Plate.
F.8.6.2 Outside Primary Structure
When Non Crushable Object(s) are located outside the Primary Structure forward of the Anti Intrusion Plate:
a. The combination of the Impact Attenuator Assembly and Non Crushable Object(s) must not exceed the peak deceleration specified in F.8.7.2
b. Any of the following methods may be used to prove the design does not exceed 120 kN:
Physical testing of the Impact Attenuator Assembly including any required Non Crushable Object(s).
Combining the peak force from physical testing of the Impact Attenuator Assembly with the failure load for the mounting of the Non Crushable Object(s), calculated from fastener shear and/or link buckling
Combining the “standard” Impact Attenuator peak load of 95 kN with the failure load for the mounting of the Non Crushable Object(s), calculated from fastener shear and/or link buckling
