25、AS620 ON A STAINLESS STEEL BAND NOT OVER 1.0 in WIDE OR ON THE END FITTING COLLAR. THE CHARACTERS SHALL BE A MINIMUM OF .06 in HIGH. THE BAND SHALL BE SO DESIGNED AS TO REMAIN TIGHT ON THE HOSE TO PREVENT RELATIVE MOTION AND CHAFING. IT SHALL BE OF SUFFICIENT STRENGTH TO PREVENT REMOVAL BY HAND. 4.

26、CONSTRUCTION AND PERFORMANCE PER AS620. FITTINGS SHALL BE PERMANENTLY ATTACHED TO HOSE. /5/ LENGTH “L” IS A THREE DIGIT NUMBER OF WHICH THE FIRST TWO DIGITS DESCRIBE THE HOSE ASSEMBLY LENGTH IN WHOLE INCHES, AND THE THIRD DIGIT, THE FRACTION OF AN INCH IN EIGHTHS. LENGTH “L” IS MEASURED FROM “GAGE P

27、OINT” TO “GAGE POINT.” SEE TABLE 2 FOR LENGTH TOLERANCES. /6/ TO CONVERT “GAGE POINT” TO “GAGE POINT” TO “END” TO “END” MEASUREMENT, ADD TO “L” THE APPROPRIATE TABLE 8 CORRECTION FACTOR FOR EACH END FITTING. /7/ SPIRAL ABRASION COVER WHEN ASSEMBLED IN THE STRAIGHT CONDITION ON THE HOSE, SHALL HAVE A

28、N AVERAGE GAP BETWEEN SPIRALS NOT EXCEEDING .05 in. DISPLACEMENT OF THE SPIRAL COVER, CAUSING A GREATER GAP, SHALL NOT BE CAUSE FOR REJECTION IF THE SPIRALS CAN BE REPOSITIONED TO MEET THE GAP REQUIREMENT. ENDS OF THE SPIRAL COVER SHALL BE TERMINATED WITH A LENGTH OF AMS-DTL-23053/5 BLACK POLYOLEFIN

29、 TUBING PER TABLE 6 AND FIGURE 2. /8/ BRAIDED POLYESTER ABRASION COVER SHALL FORM AN INTEGRAL, PERMANENT PART OF THE HOSE AND SHALL TERMINATE A MAXIMUM OF .625 in FROM THE END OF THE END FITTING COLLAR. ENDS OF POLYESTER ABRASION COVER MAY BE TERMINATED WITH A LENGTH OF AMS-DTL-23053/11 (FEP) CLASS

30、1 OR 2, COLOR CLEAR, PER TABLE 6 AND FIGURE 2. /9/ HOSE ASSEMBLY INSIDE DIAMETER SHALL BE VERIFIED BY PASSING THE DESIGNATED, OR LARGER, SPHERICAL BALL PER TABLE 7 THROUGH THE ASSEMBLY. /10/ DISTANCE ACROSS CORNERS OF COUPLING NUT, NIPPLE HEX OR SOCKET HEX MAY EXCEED THIS DIMENSION.

34、HE LARGEST SIZE FIRESLEEVE AS QUALIFIED BY THE VARIOUS HOSE ASSEMBLY MANUFACTURERS. THE SLEEVE MAY STRETCH OVER A FITTING, OR WRINKLE OVER THE HOSE DUE TO SLEEVE LENGTH TO ALLOW HOSE BENDING. THE SLEEVE MAY BE COMPRESSED OVER THE HOSE FOR MEASUREMENT OR CLAMPING. IN THIS CASE A WRINKLE MAY OCCUR OVE

35、R APPROXIMATELY 10% OF THE SLEEVE CIRCUMFERENCE. /14/ ADD “AS1055 TYPE IIa CLASS A-S/P” OR “AS150 TYPE IIIaA” TO IDENTIFICATION MARKING TO SHOW LEVEL OF COMPLIANCE, “FIRE RESISTANT” (5 min), WITH AS1055 OR AS150. 15. STANDARD COUPLING NUTS SHALL BE IN ACCORDANCE WITH AS21921 OR AS4370. NONSTANDARD C

36、OUPLING NUTS MAY BE USED BUT SHALL COMPLY WITH THE REQUIREMENT (b) OF NAS1760 FOR NONSTANDARD NUTS AND SHALL BE RETAINED BY THE END FITTING. /16/ THE FITTING ORIENTATION DASH NUMBER IS A THREE DIGIT NUMBER DEFINING THE RELATIVE POSITION OF THE END FITTINGS IN 1 INCREMENTS (EXAMPLE 090 = 90). FITTING

37、 ORIENTATION SHALL BE MEASURED COUNTER CLOCKWISE FROM THE NEAREST END FITTING, WHICH SHALL BE IN THE RELATIVE 000 POSITION (SEE FIGURE 3).
