3.5.1 Functional requirements.

3.5.1.1 Rough handling test (when specified, see 6.2). When packs have been tested in accordance with 4.7.2.1,

all materials and components comprising each pack shall be free from damage or evidence of misplacement that

might affect the utility of the preservation method or pack. The capacitors and associated accessories within the

tested packs shall show no visible signs of damage. When specified in the contract (see 6.2), functional tests in

accordance with the group A inspection requirements of the applicable commodity specification or drawing shall be

conducted on those capacitors subjected to the rough handling test to determine freedom from operational

malfunction. The examination of the capacitors tested under this group A inspection shall be in accordance with

visual and mechanical inspection requirements specified in the applicable capacitor commodity specification or

drawing.

3.5.1.2 Leakage test (when applicable). When a barrier enclosed unit pack has been tested in accordance with

4.6.2.2, there shall be no evidence of moisture within the unit pack.

3.6 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally

preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the

operational and maintenance requirements, and promotes economically advantageous life cycle costs.
