LENGTH “L“ IS MEASURED FROM GAGE POINT TO GAGE POINT. SEE TABLE 3 FOR AVAILABLE LENGTH INCREMENTS. IN THE EXAMPLE OF PAR
13、T NUMBER BELOW, LENGTH “L“ IS DEFINED BY A FOUR DIGIT DASH NUMBER DESCRIBING THE HOSE ASSEMBLY LENGTH IN MM. 2. TO CONVERT “GAGE POINT TO GAGE POINT“ TO “END TO END“ MEASUREMENT, ADD TO “L“ THE APPROPRIATE TABLE 2 CORRECTION FACTOR FOR EACH END FITTING. 3. THE HOSE ASSEMBLIES ARE INTENDED FOR USE IN
14、 LOW AND MEDIUM PRESSURE PNEUMATIC SYSTEMS UP TO 425 C WITH SHORT DURATION EXCURSIONS TO 650 C. MAXIMUM RATED OPERATING PRESSURE IS DEPENDENT ON AMBIENT OPERATING TEMPERATURE AND CAN BE DETERMINED FROM MA2100, TABLE 2. 4. DIMENSIONS IN MM. DIMENSIONING AND TOLERANCING ARE PER ANSI Y14.5M AND UNIT SY
15、MBOLS ARE PER ANSI Y10.19, SAE J916 AND ANSI Z210.1. 5. A TRUE CIRCULAR CROSS SECTION IS NOT REQUIRED THROUGH THE END FITTING. HOWEVER, A BALL OF THE SIZE DIAMETER LISTED IN TABLE 2 SHALL PASS THROUGH THE END FITTING AFTER THE END FITTING IS ATTACHED TO THE HOSE ASSEMBLY. 6. DO NOT USE UNASSIGNED SI
