FF-P-110 Padlock, Changeable Combination \(Resistant To Opening By Manipulation And Surreptitious Attack\)This specification covers changeable combination padlocks designed to conform to the standards for security equipment as set forth in the "National Security Council Directive Governing the Classification, Downgrading, Declassification and Safeguarding of National Security Information". The padlocks are required to resist opening by manipulation and surreptitious techniques for the period of time specified. The padlocks are intended for use as indicated in 6.1. The padlocks are not tested for forced opening.

FF-P-110J

The padlock shall perform normally as specified throughout section 3 of this specification while at

this temperature (see 3.2).

4.6.3.11 Humidity effects test. To determine resistance of the padlock to corrosion and

functional degradation due to high humidity (ocean marine environments), conduct the salt spray

test of ASTM F883 for 24 hours. After the test, the padlock shall operate properly (lock and

unlock). The padlock combination change capabilities shall not have been affected by the test and

shall be confirmed by making three combination changes while locking and unlocking the padlock

between each combination change.

4.6.3.12 Heat resistance. Suspend the padlock in an oven that is heated to 300 �F (149 �C).

Sustain this condition for five minutes. Allow the unit to cool to room temperature. Operate the

padlock through all functions (opening, closing, combination change). The heat shall not have

modified the normal performance of the padlock (see 3.3.1).

4.6.3.13 Wear and lubricant test. Prior to testing, record the torque required to dial the

combination for opening. After the torque is determined, perform the cycle test of

ASTM F883 for 5,000 cycles. Upon conclusion of the cycle test, the lock shall open and lock

properly when the correct combination is dialed and shall operate within 10 percent of torque

required to turn the dial of the new lock. The dial tolerance for opening the lock shall not exceed

the 1/4 dial division (see 3.4.1). Upon conclusion of the cycle test, the lock shall open and close

properly for each of 50 different combination changes when the proper combination is dialed.

The dial tolerance for opening and the 10 percent torque variation specified above shall not be

exceeded when opening and closing the lock for each of the 50 combination changes.

4.7 Inspection of preparation for delivery. An inspection shall be made to determine that the

packaging, packing, and marking comply with the requirements in section 5 of this specification.

Defects shall be scored in accordance with Table III. For examination of interior packaging, the

sample unit shall be one shipping container fully prepared for delivery, selected at random just

prior to the closing operations. Sampling shall be as specified in contract. Defects of closure

listed shall be examined on shipping containers fully prepared for delivery. The lot size shall be

the number of shipping containers in end item inspection lot.
