MATERIAL:
SEALING RING INSERT – THERMALLY STABILIZED, MELTABLE, THERMOPLASTIC.
SOLDER RING – AS TABULATED.
SHRINKABLE SLEEVE – EXPANDED, TRANSPARENT, IRRADIATED POLYVINYLIDENE FLUORIDE, BLUE TINT.
EXAMPLE OF PART NUMBER:
NAS1744-1 = IMMERSION RESISTANT SPLICE FOR USE WITH WIRE HAVING TINNED OR SILVER PLATED CONDUCTORS WITH CONTINUOUS INSULATION TEMPERATURE RATING OF 125 °C.
NAS1744-7 = IMMERSION RESISTANT SPLICE FOR USE WITH WIRE HAVING NICKEL PLATED CONDUCTORS WITH CONTINUOUS INSULATION TEMPERATURE RATING OF 125 °C MIN.
NOTES:
(1) DIMENSIONS IN INCHES.
/2/ THE CMS RANGE AS TABULATED SHALL NOT BE EXCEEDED. THE FIGURES ARE BASED ON TOTAL SURFACE AREA TO BE SOLDERED AND TOTAL MASS OF THE CONDUCTORS IN ORDER TO PROVIDE OPTIMUM SOLDER FLOW.
(3) THIS STANDARD TAKES PRECEDENCE OVER DOCUMENTS REFERENCED HEREIN.
(4) UNLESS OTHERWISE SPECIFIED, PART INVENTORY MANUFACTURED TO PREVIOUS REVISIONS OF THE APPLICABLE DRAWING OR SPECIFICATION MAY BE PROCURED AND USED UNTIL STOCK IS DEPLETED.
(5) REFERENCED DOCUMENTS SHALL BE THE ISSUE IN EFFECT ON DATE OF INVITATIONS FOR BID.
(6) DIMENSIONING AND TOLERANCING PER ANSI Y14.5M-1982.
