MARKING SHALL BE PER AS620 ON A STAINLESS STEEL BAND NOT OVER 1.0 INCH WIDE OR ON THE END FITTING COLLAR. THE CHARACTERS SH
21、ALL 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 BE OF SUFFICIENT STRENGTH TO PREVENT REMOVAL BY HAND. 4. CONSTRUCTION AND PERFORMANCE PER AS620. FITTINGS SHALL BE PERMANENTLY ATTACHED TO HOSE. /5/ LENGTH
22、 “L” IS 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
23、 CONDITION ON THE HOSE SHALL HAVE AN AVERAGE GAP BETWEEN SPIRALS NOT EXCEEDING .05 INCH. 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 LENGT

27、F” (15 MIN), 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 INSTAL
28、LATION, 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, OR WRINK
29、LE 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 IDENTIFICATION MAR

NONSTANDARD COUPLING NUTS MAY BE USED PROVIDED THEY ARE DIMENSIONALLY AND FUNCTIONALLY EQUIVALENT AND PROV
31、IDED THEY CANNOT BE REMOVED FROM THE FITTING AND USE THE SAME MATERIALS. /15/ THE FITTING ORIENTATION DASH NUMBER IS A THREE DIGIT NUMBER DEFINING THE RELATIVE POSITION OF THE END FITTING IN 1 INCREMENTS (EXAMPLE 090 = 90). FITTING ORIENTATION SHALL BE MEASURED COUNTERCLOCKWISE FROM THE NEAREST END
32、FITTING, WHICH SHALL BE IN THE RELATIVE 000 POSITION (SEE FIGURE 3). WHEN END FITTINGS ARE POINTED IN THE SAME DIRECTION, THE DASH NUMBER SHALL BE 000. 16.
