NOTES:

1. APPLICABLE STANDARDS/SPECIFICATIONS:

A. ASME Y14.100-2004

B. ASME Y14.5M-1994

2. MATERIAL: PIN ASSEMBLY TO BE MOLDED

WITH VENDOR COMPOUND SM07884 OR

AN APPROVED EQUAL AS DEMONSTRATED

BY VEHICLE TEST AT YUMA PROVING

GROUNDS AND APPROVED BY TACOM.

PIN ASSEMBLY MUST MEET A 4000 MILE

LIFE USING 20% FAILURE CRITERIA PER

VEHICLE SET WHILE BEING TESTED ON A

68,500 LBS M109A6. THE PIN ASSEMBLY

MILEAGE SPECIFIED REQUIRES THAT

EVERY 1,000 MILES THE STRANDS

SWITCH VEHICLE SIDES. TESTING IS TO

BE IN ACCORDANCE WITH TRADOC

OPERATION MODE. ALL NEW VENDOR/COMPOUND

COMBINATIONS TO BE QUALIFIED.

EACH QUALIFICATION TEST DATA IS

MAINTAINED BY THAT CONTRACTOR

LISTED IN TABLE I AND WILL BE MADE

AVAILABLE FOR REVIEW TO THE LOCAL

DCMA-QAR OR SUBCONTRACTOR UPON

REQUEST.

THE LOCAL DCMA-QAR WILL BE PROVIDED

THIS DATA PRIOR TO INITIATION OF

PRODUCTION CONTACT AND WILL BE USED

FOR ACCEPTANCE PARAMETERS.

3. FOR IN PROCESS INSPECTION AND PRODUCTION

CONTROL UTILIZE TABLE III OF MIL-DTL-11891.

TEST FREQUENCIES PER MIL-DTL-11891.

TESTS TO BE PERFORMED INCLUDE:

A. SPECIFIC GRAVITY IN ACCORDANCE WITH

ASTM D792

B. HARDNESS IN ACCORDANCE WITH ASTM D2240

C. TENSILE STRENGTH IN ACCORDANCE WITH

ASTM D412

D. TENSILE STRENGTH (AGED) IN ACCORDANCE

WITH ASTM D573

E. ULTIMATE ELONGATION IN ACCORDANCE

WITH ASTM D412

F. TENSILE STRESS AT 200% STRAIN (MODULUS)

IN ACCORDANCE WITH ASTM D412

ASTM E1131

H. VULCANIZATION USING OSCILLATING DISK CURE

METER IN ACCORDANCE WITH ASTM D2084

I. ADHESION IN ACCORDANCE WITH ASTM D429

J. COMPRESSION SET IN ACCORDANCE WITH

ASTM D395

K. BRITTLENESS POINT OF FLEXIBLE POLYMERS IN

ACCORDANCE WITH ASTM D2137 GC MASS SPEC

THE REQUIRED ACCEPTANCE VALUES FOR

EACH OF THE TESTS HAVE BEEN

ESTABLISHED DURING DEVELOPMENT OF

THE TEST COMPOUND.

4. PRE-QUALIFICATION REQUIREMENTS FROM

MIL-DTL-11891 RELATING TO BUSHINGS

SHALL BE APPLICABLE EXCEPT THE

6. FOR A BUSHING DESIGN NOT CONFORMING

TO THIS DRAWING, SUPPLIER MAY SUBMIT

THEIR BUSHING DESIGN FOR QUALIFICATION.

THE SUPPLIER MUST SUBMIT THEIR

DRAWING TO TACOM FOR APPROVAL PRIOR

TO BEGINNING PRODUCTION OF QUALIFICATION

HARDWARE. ONLY BUSHINGS CONFORMING

TO THIS DRAWING, AN APPROVED VENDOR'S

DRAWING LISTED IN APPROVED SOURCE(S)

OF SUPPLY TABLE, OR A QUALIFIED SUPPLIER'S

DRAWING APPROVED BY TACOM MAY BE

USED IN PRODUCTION. ANY CHANGES FROM
