MARKING SHALL BE PER AS620 ON A STAINLESS STEEL BAND NOT OVER 1.0 in WIDE OR ON THE END FITTING COLLAR. THE CHARACTERS SHALL B
21、E 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. CONSTRUCTION AND PERFORMANCE PER AS620. FITTINGS SHALL BE PERMANENTLY ATTACHED TO HOSE. /5/ LENGTH “L” IS
22、 A THREE DIGIT NUMBER OF WHICH THE FIRST TWO DIGITS DESCRIBE THE HOSE ASSEMBLY LENGTH IN WHOLE INCHES, AND THE THIRD DIGIT IN FRACTION OF AN INCH IN EIGHTHS. LENGTH “L” IS MEASURED FROM “END” TO “END.” SEE TABLE 2 FOR LENGTH TOLERANCES. /6/ SPIRAL ABRASION COVER WHEN ASSEMBLED IN THE STRAIGHT CONDIT
23、ION ON THE HOSE SHALL HAVE AN 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.

27、, WITH AS1055 OR AS150. /11/ THE CUT ENDS OF THE FIRESLEEVE SHALL BE COATED WITH RTV SILICONE RUBBER, OR EQUIVALENT, PRIOR TO INSTALLATION TO PREVENT WICKING OF FLUID. THE FIRESLEEVE ENDS SHALL BE SECURED TO THE HOSE ASSEMBLY END FITTINGS WITH CORROSION RESISTANT STEEL BANDS. AFTER INSTALLATION, CRA
28、CKS OR VOIDS IN THE FIRESLEEVE, WHICH EXPOSE THE FIBERGLASS, SHALL BE COATED WITH RTV SILICONE. /12/ THE TABLE 3 SLEEVE DIAMETERS ARE THE AS1072 MAXIMUM FOR THE LARGEST SIZE FIRESLEEVE AS QUALIFIED BY THE VARIOUS HOSE ASSEMBLY MANUFACTURERS. THE SLEEVE MAY STRETCH OVER A FITTING, OR WRINKLE OVER THE
