Spool DR- fully loaded with Wire WD-1( )/TT (Gee 6.3), shall be cranked
50 to 60 revolutions per minute continuously for 240 hours, consisting of ten
24-hour cycles. The cranking may be stopped for a ·period not to exceed 15 mtnutes
per 24-hour cy.r.le for lubrication. At the conclusion of the test period, the
reeling mar·hine shall be disassembled and the steel bearings and the interior
surface of their housing shall be inspected for. conformance with 3.5.2.
4.7 Interchangeability. The dimensions listed below shall be gaged or measured to determine conformance to the physical interchangeability requirement of 3.3. When a listed dimension is not within specified or design limits, it shall be considered a major defect.
