1. 0 PURPOSE 1.1 To assure compliance of production units of the Shock Arrestor Assembly with referenced drawings.

2.0 SCOPE 2.1 This test establishes both visual and functional charac-teristics which could be expected to vary through dimen-sional variation or improper assembly and adjustment.

5.1.2 Each unit shall be visually inspected to assure'ompleteness of assembly, freedom from burrs and sharp edges, alignment of parts, security of fasteners, and dimensional integrity.

5.1.3 Units shall be visually inspected for general appearance of plating, painting, freedom from nicks and damage of finishes.

5.1.4 Units shall be inspected to assure the accuracy and legibility of marking and identification.

OP 6.0 FUNCTIONAL TESTS Following tests will be performed with shock arrestors in-stalled on 1801106/1801102 TF-1 Test Stand.

OF 6.1 Proof Load 6000 lbs.

6.1.1 With arrestor installed on test stand, move carriage to position I.

Lock inertia mass.

Set air,. pressure gage on air-hydraulic booster pump to 64 P.S.I.

Actuate foot. pedal or lever on booster pump, applying 6000 lbs. to the unit.

(Note:

6220 P.S.I.

= 6000 lbs.)

Hold pressure for approximately 5 secs.

Release pressure; dis-connect unit from position I and move carriage to position II on test stand.

Unlock or free inertia mass.

6.2 Breakawa Friction Test 60 lbs.

6.2.1 With arrestor in position II on test stand and inertia mass in free state, secure arrestor with pin to clevis.

Breakaway friction shall be checked at 3 positions of scale, both extending and retracting, 4 inch from each end and one place in approximate mid-position of scale.

Failure of arrestor to meet this portion of test shall be cause for rejection.

6.3.1 e Test (5 in./lbs. max.)

1 W'th carriage, in position II on test stand, adjust pressure gage to 90 P.S.I.

Install torque collet and secure to inertia mass.

Slide torque meter to engage with torque collet and secure in place.

Apply 90 P.S.I. in both directions by moving valve handle from one direction to the next direc-tion without any hesitation and in a smooth manner.

Record torque value in each direction, compression and extension.

Readings in either direction shall not. exceed 5,in./lbs.

Release torque meter and torque collet from unit prior to Lost Motion test.

6.3.1.1 Failure of arrestor to meet this portion of the test shall be subjected to further test on acceleration test fixture 1801 TF-2.

If acceleration at this time is less than

.51 sec. in 1.00 inch of travel, the arrestor shall be rejected.

6.4 Lost Motion (. 040 max. )

6.4.1 W'th carriage in position II on test stand, lock inertia mass and position arrestor in approximately mid-position of scale.

Secure indicator and engage to end cap of arrestor.

Apply 90 P.S.I. pressure in PACIFIC SCIENTIFIC

Apply the.load in the opposite direction and record lost motion.

Lost motion shall not exceed
