19、TACHED TO THE HOSE. OPERATING CHARACTERISTICS: SEE MA2007. MATERIALS: HOSE AND FITTINGS - PER MA2007. SLEEVES - SEE APPLICABLE STANDARD, TABLE 2. MARKING: MARKING SHALL BE PER MA2007 ON A STAINLESS STEEL BAND NOT OVER 25.4 MM WIDE, OR ON THE COLLAR. THE CHARACTERS SHALL BE A MINIMUM OF 1.6 MM HIGH.
20、THE BAND SHALL BE SO DESIGNED AS TO REMAIN TIGHT ON THE HOSE TO PREVENT RELATIVE MOVEMENT AND RESULTANT CHAFING. IT SHALL BE OF SUFFICIENT STRENGTH TO PREVENT REMOVAL BY HAND. HOSE ASSEMBLY DATE AND “PT“ SYMBOL SHALL BE ELECTROETCHED ON THE BAND OR ON AN END FITTING OR A FIRESLEEVE CLAMP. FLAG NOTES
21、: /1/ LENGTH “L“ IS A FOUR DIGIT NUMBER OF WHICH THE FIRST THREE DIGITS DESCRIBE THE HOSE ASSEMBLY LENGTH IN WHOLE CENTIMETERS (CM), AND THE FOURTH DIGIT, THE FRACTION OF A CM IN MILLIMETERS. LENGTH “L“ IS MEASURED FROM “FACE OF SEAT“ TO “FACE OF SEAT“. FOR LENGTH INCREMENTS AND TOLERANCES SEE TABLE
22、 3. /2/ A TRUE CIRCULAR CROSS SECTION IS NOT REQUIRED THROUGH THE FITTING I.D. HOWEVER, THE APPLICABLE BALL DIAMETER LISTED IN TABLE 1 SHALL PASS THROUGH THE END FITTING AFTER IT IS ASSEMBLED TO THE HOSE. /3/ DISTANCE ACROSS CORNERS OF THE COUPLING NUT MAY EXCEED THIS DIMENSION. /4/ STANDARD COUPLIN
23、G NUTS SHALL BE IN ACCORDANCE WITH MA2058 AND MATE WITH MA2094 60 CONE FITTING ENDS. NONSTANDARD COUPLING NUTS MAY BE USED PROVIDED THEY ARE DIMENSIONALLY AND FUNCTIONALLY EQUIVALENT AND PROVIDED THEY CANNOT BE REMOVED FROM THE FITTING. NUTS SHALL MEET TORQUE TEST REQUIREMENTS PER MA2007. /5/ DIAMET

DISPLACEMENT
26、OF THE COILS OF THE SLEEVE, CAUSING A GREATER GAP, SHALL NOT BE CAUSE FOR REJECTION IF THE COILS CAN BE REPOSITIONED TO MEET THE GAP REQUIREMENTS. ENDS OF THE COIL SLEEVE SHALL BE TERMINATED WITH A LENGTH OF HEAT SHRINKABLE SLEEVING IN ACCORDANCE WITH TABLE 5 AND FIGURE 2. CODE “B“ (NYLON COIL) ABRA
27、SION SLEEVES SHALL BE TERMINATED WITH SAE-AMS-DTL-23053/5 CLASS 1 OR 3, COLOR BLACK. CODE “L“ (COIL ABRASION) SLEEVES SHALL BE TERMINATED WITH MIL-I-23053/12A, CLASS 1, COLOR TRANSPARENT, PTFE.
