MIL-G-8968(ASG)

3.5.8 Certification of welders. - All welding shall be accomplished by welders

certified in accordance with class A of MIL-T-5021.

3.5.9 Transportabilitya - The generating plant shall meet the air transportabil-

ity requirements of MIL-A-8421. Additionally, when specified (see 6.2) the plant

shall be compatible with amphibious type operations. Consideration shall be-given

to embarking and debarking the plaint in amphibious ships of the IST type, The plant

shall be capable of being moved through salt water to the depth equal to the height

of the wheel without detrimental effect to equipment.

3.5.9.1 Mobility . - The generating plant vehicle assembly shall be of full

trailer configuration designed to meet mobility requirements of type III, group c of

MIL-M-8090.

3.5.9.2 Aircraft loading and transport. - The generating plant

design and con-

figuration shall be such as to provide for loading and transport by

type C-130 and

larger aircraft, Applicable aircraft cargo compartment and loading

door dimensional

data are contained in Bulletin No. 518 and NAVAIR 01-85WBB-1-1, for

Navy C-2A aircraft,

3.5.9.3 Transport acceleration forces. - The generating plant shall be designed

and constructed to withstand the flight and taxiing acceleration forces specified in

MIL-A-8421 during transport and handling. The plant shall withstand like forces as .

imposed in MIL-A-8421 while being transported on railroad car, seagoing vessel, or

highway transporter.

3.5.9.3.1 Vibration forces, - The generating plant shall not be damaged by the

transport vibration forces specified under Method 514, Procedure X of MIL-STD-810

for category g equipment, when completely assembled and ready for shipment.

3.5.9.4 Emergency landing acceleration forces, - The completely assembled gen-

erating plant prepared for transport shall withstand the emergency landing load shock

forces specified in MIL-A-8421, except that the shock pulse shall be an approximate

one-half sine wave of not less than 30 milliseconds or more than 40 milliseconds'

duration without breaking loose from its tiedowns or parts of the equipment leaving

the original envelope of the vehicle,

3.5.9.5 Amphibious operation. - When specified (see 6.2), the generating plant

design, configuration, and construction shall provide for loading into, transport by,

and disembarking through the surf and over the beach from amphibious ships of the IST

type. The design configuration, and construction shall also be such to permit fording

or being moved through fresh or salt water to a depth equal to the height of the wheels

and tires without damage to or detrimental effect on the equipment.
