THIS CATALOG PAGE IS FOR REFERENCE ONLY. REQUEST A

CERTIFIED UMPCO DRAWING FOR ACTUAL SPECIFICATIONS.

ANY CONFLICT BETWEEN THIS DOCUMENT AND THE CERTIFIED

DRAWING, THE CERTIFIED DRAWING WILL TAKE PRECEDENCE.

IF THE DOCUMENT IS CONTROLLED BY ANY OTHER SOURCE

THAN UMPCO, THE CERTIFIED DRAWING MUST BE PURCHASED

7100 LAMPSON AVE * PO BOX 5158 * GARDEN GROVE, CA 92846-5158 SALES: (714) 897-3531 * BUS: (714) 897-3536 * FAX: (714) 897-2611

(1) DIP TEST: SAMPLES SHALL BE DIPPED IN P-D-680 SOLVENT AND ALLOWED TO DRY AT ROOM TEMPERATURE FOR 24 HOURS. THIS

PROCEDURE SHALL BE REPEATED 10 TIMES.

(2) TESTS SHALL BE IN CONDUCTED ACCORDANCE WITH ASTM D412 ON THE FABRIC REINFORCED CUSHION TEST SPECIMEN (1/2 INCH,

WIDE STRIPS CUT FROM ACTUAL CUSHIONS FROM FABRIC WEAVE AT 45 INCHES TO THE DIRECTION OF PULL). THE TENSILE STRENGTH

AND PERCENT ELONGATION SHALL BE MEASURED WHEN THE FABRIC REINFORCING MATERIAL BEGINS TO SEPARATE FROM THE

ELASTOMER. TENSILE STRENGTH WILL BE BASED ON OVERALL THICKNESS OF RUBBER AND FABRIC REINFORCING MATERIAL.

SPECIMEN FAILURES DUE TO FABRIC SEPARATION AT THE TEST FIXTURE JAWS SHALL BE DISREGARDED AND ANOTHER SAMPLE

TESTED.

(3) THE PERMISSIBLE VARIATION IN SPECIFIC GRAVITY DURING ACTUAL PRODUCTION FOR THAT VALUE ESTABLISHED IN FIRST ARTICLE

TESTS SHALL BE ±. 03.

(4)

TABULATED HARDNESS RANGE APPLICABLE TO THE AS RECEIVED, NON-SUPPORTED CONDITION. THE REQUIRED HARDNESS, RANGE

FOR THE AS MOLDED CONDITION IS 65 TO 80.

NOTES: UNLESS OTHER WISE SPECIFIED

1.

DIAMETER “D” IS THE NOMINAL DIAMETER FOR WHICH A CLAMP SIZE IS INTENDED FOR USE. DIAMETER “D” SHALL BE VERIFIED BY

THE “DIAMETRAL RETENTION” TEST PER MIL-C-85052.

2.

DIMENSION “E’ SHALL BE MEASURE WITH THE CLAMP INSTALLED ON A MANDREL OF “D” DIAMETER ±.001 AND A .0625 ±.005 SPACER

BETWEEN THE UPPER AND LOWER FEET.

3.

WEDGE SHALL BE REQUIRED ON –6 AND LARGER CLAMP CUSHIONS. THE WEDGE SHALL BE MOLDED AS AN INTEGRAL PART OF THE

CUSHION AND CONTOURED TO FIT “D” DIAMETER. WEDGE SHALL TOUCH LOWER/BASE PORTION OF CUSHION WHEN CLAMP IS

INSTALLED ON A MANDREL DEFINED IN PROCUREMENT SPECIFICATION AND WHEN THERE IS NO GAP BETWEEN BOTH FEET.

4.

STIFFENING BEAD SHALL BE REQUIRED ON SIZE –4 AND LARGER CLAMPS. SIZE –2 AND –3 CLAMPS USE A PLAIN JOGGLE ONLY. ALL

RADII ON THE STIFFENING BEAD SHALL BE SMOOTH AND BLENDED.

5.

SEE SAE AS5874 DRAWING.

6.

METAL BAND SHALL HAVE ALL BURRS, SHARP EDGES, AND SCALE REMOVED.

7.

DIMENSIONAL TOLERANCES AND SYMBOLS PER ANSI Y14.5M-1982.

8.

FIGURE IN PHANTOM SHOWS THE APPROXIMATE FREE STATE, I.E. THE “AS RECEIVED” POSITION/CONDITION OF THE CLAMP.

9.

REFERENCE DIMENSIONS “J” AND “Y” APPLY TO FEATURES INTENDED TO PROVIDE MAXIMUM SUPPORT FOR THE LOWER FOOT BY

CLOSELY FITTING THE UPPER FOOT BEND RADIUS TO THE STIFFENING BEAD RADIUS WHEN CLOSED AGAINST EACH OTHER.

10.

EXCEPT FOR CLAMP BAND SIZES –2, -3 AND –4 SHALL BE THE COMPLETE VENDOR’S DESIGNATION AND MANUFACTURER’S NAME

(“UMP” IS ACCEPTABLE OPTION FOR UMPCO) OR TRADEMARK OR CAGE CODE. IDENTIFICATION SHALL BE IMPRESSION STAMPED ON

THE BAND IN AN AREA NOT COVERED BY THE CUSHION. ALL IDENTIFICATION SHALL BE LOCATED ABOVE THE TUBE/PAYLOAD

THEORETICAL CENTERLINE.

11.

PROPERTY MEASUREMENTS SHALL BE PERFORMED IMMEDIATELY AFTER REMOVAL FROM THE IMMERSION BATH.

12.

IN ADDITION TO ADHERING TO THE APPLICABLE MATERIAL SPECIFICATIONS DEFINED HEREIN FOR THE CLAMP CUSHIONS AND CLAMP

BANDS, THE CLAMP ASSEMBLIES (BAND AND INSTALLED CUSHION) ARE QUALIFIED BY PERFORMANCE AND SHALL HAVE

SUCCESSFULLY COMPLETED THE PERFORMANCE TESTING REQUIREMENTS LISTED BELOW. THE MOLDED CUSHION MATERIAL SHALL

SUCCESSFULLY COMPLETE THE FLUID COMPATIBILITY TESTING DEFINED WITHIN TABLE 2, PHYSICAL PROPERTIES.

DIAMETRAL RETENTION PER MIL-C-85052.

COMPRESSION SET PER MIL-C-85052, AIR AGE AT 212°F, NOT TO EXCEED FOR AVERAGE OF 3 SPECIMENS.

VIBRATION AND TRANSMISSIBILITY PER MIL-C-85052.

HORIZONTAL BURN TEST PER FAR 25.853 (b-3)

SPECIMEN/SLAB: APPROXIMATELY 3.00 (W) X 5.00 (L)

MAXIMUM BURN RATE: 2.5 INCHES PER MINUTE.

RETENTION OF QUALIFICATION REQUIRES THAT EACH APPROVED VENDOR IN CONJUNCTION WITH THE CUSHION MOLDER PERFORM

THE ABOVE DEFINED VIBRATION TESTING AND THE FLUID COMPATIBILITY TESTING DEFINED IN TABLE 2 NO LESS THAN ONCE EVERY

(6) YEARS FROM THE COMPLETION DATE OF THE INITIAL TESTING.

UNLESS OTHERWISE SPECIFIED, RESULTS ARE AN AVERAGE OF 5 SPECIMENS.

TOLERANCE ON TEMPERATURE IS ±5°F.
