21、itN FOR CURRENT QPL ON-LINE. 3. MARKING SHALL BE PER AS620 ON A STAINLESS STEEL BAND NOT OVER 1.0 INCH WIDE OR ON THE END FITTING COLLAR. THE CHARACTERS SHALL BE A MINIMUM OF .06 INCH HIGH. THE BAND SHALL BE SO DESIGNED AS TO REMAIN TIGHT ON THE HOSE TO PREVENT RELATIVE MOTION AND CHAFING. IT SHALL
22、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 A FOUR DIGIT NUMBER OF WHICH THE FIRST THREE DIGITS DESCRIBE THE HOSE ASSEMBLY LENGTH IN WHOLE INCHES, AND THE FOURTH DIGIT IN FRACTION O
23、F 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 CONDITION ON THE HOSE SHALL HAVE AN AVERAGE GAP BETWEEN SPIRALS NOT EXCEEDING .05 INCH. DISPLACEMENT OF THE SPIRAL COVER, CAUSING A GREATER GA
24、P, SHALL NOT BE CAUSE FOR REJECTION IF THE SPIRALS CAN BE REPOSITIONED TO MEET THE GAP REQUIREMENT.

THE FIRESLEEVE ENDS SHALL BE SECURED TO THE HOSE ASSEMBLY END FITTINGS WITH CORROSION RESISTANT STEEL BANDS. AF
28、TER INSTALLATION, CRACKS 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
29、, 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 OVER APPROXIMATELY 10% OF THE SLEEVE CIRCUMFERENCE. /13/ ADD “AS1055 TYPE IIa CLASS A-S/P” OR “AS150 TYPE IIIaA” TO IDENTIFI
