6、Y. Type “K” thermocouple conductors are typically used as extension leads for aerospace application. These wires are only to be used in a matched pair and procured under AS5419. Thermocouple extension wires are calibrated for use together in fabricating thermocouples. If each leg of the thermocouple
7、 extension wire is from a different lot, recalibration of the thermocouple pair will be required.FIGURE 1 - Design and ConstructionComponent wire insulation system must conform to the similar wire type designated in Table 1of AS5419. Manufacturers must be qualified to MIL-DTL-25038/3 to produce this

The printed mar
15、king shall be legible, black in color, and withstand a durability test of 125 cycles (250 strokes) (min), 150 grams weight. The size of the printed characters shall be consistent with the magnitude of the surface upon which it is printed. The distance between the end of one mark and the beginning of
16、 the next shall be a maximum of 12 in. The printed marking shall be applied with the vertical axes of the print characters lengthwise on wire whose nominal diameter is 0.050 in (1.27 mm) or smaller. The vertical axes of the printed characters may be crosswise or lengthwise on wire whose nominal diam
17、eter is 0.051 in (1.30 mm) or larger.ADDITIONAL CONDUCTOR REQUIREMENTSSTRAND MATERIAL: Type KPH and KPS strands shall be made from an alloy of 90% nickel - 10% chromium and Type KNH and KNS strands shall be made from an alloy of 95% nickel - 2% aluminum - 2% manganese - 1% silicon and minor traces o
18、f other materials and shall conform to ANSI-MC96.1.SPLICES: Splices in individual strands or groups of individual strands shall be butt brazed with silver solder. Splices shall be so constructed and disposed throughout the conductor that the diameter, configuration, conductor resistance, flexibility
19、, and mechanical strength of the completed conductor are not adversely affected.SOLDERABILITY: Not applicableAEROSPACE STANDARD AS5419/1 SHEET 4 OF 4 WIRE, THERMOCOUPLE, HIGH TEMPERATURE AND FIRE RESISTANT LIGHT WEIGHT, SMALL DIAMETER NICKEL/CHROMIUM (KP); NICKEL/ ALUMINUM/MANGANESE (KN) THERMOCOUPL
