1、AMSC N/A FSC 5920 MIL-PRF-23419/10C 17 April 2012 SUPERSEDING MIL-PRF-23419/10B 08 July 2005 PERFORMANCE SPECIFICATION SHEET FUSES, CARTRIDGE, INSTRUMENT TYPE, STYLE FM10, (NONINDICATING) This specification is approved for use by all Departments and Agencies of the Department of Defense. The require

2、ments for acquiring the product described herein shall consist of this specification sheet and MIL-PRF-23419. Inches mm .06 .103 .311 1.50 1.5 2.62 7.90 38.1 NOTES: 1. Dimensions are in inches. 2.

Applicable fuseholder: Grayhill Type 2-42, ultra miniature test clip or equivalent. For 7, 10, and 15 ampere fuses, use Gray

4、hill Push-post number 29-100 or equivalent. Case material: Ceramic or glass. Finish: Epoxy coating. Outgassing: When tested as specified in ASTM E595, the polymer sample shall meet the following requirements: Total mass loss (TML): Shall not exceed 1.0 percent. Volatile condensable material (VCM): S

5、hall not exceed 0.1 percent. Samples of any polymeric materials used shall be cut into pieces having 0.38 inch (9.65 mm) maximum dimension. A sample of 100 to 300 milligrams of material shall be weighed and then placed in a vacuum chamber under the following conditions: Pressure: 10-6torr or less. T

6、emperature of specimen: Maximum operating temperature of device. Exposure time: 24 hours. During this exposure, a collector plate 9.7 inches (246.4 mm) in diameter shall be held at 25 C 1 C near the sample. Immediately upon removal of the specimen and the collector plate from the chamber, they shall

7、 be weighed. The total mass loss (TML) is sample mass before exposure minus sample mass after exposure divided by the initial sample mass (expressed in percent change). The volatile condensable material (VCM) is the increase in the weight of the collector plate divided by the mass of sample (express

8、ed in percent). Outgassing (option): As an option for inspection to outgassing requirements (as stated above), a minimum of 10 grams of each polymeric material in its final processed condition may be submitted to the following NASA installation for outgassing test: Director, Material and Processes L

9、aboratory, EH41, Marshall Space Flight Center, Huntsville, AL 35812. As an alternate, a minimum of a single device utilizing each material may be submitted to the Marshall Space Flight Center for outgassing tests. Terminals: Material: Caps, 90/10, commercial brass; leads, copper. Finish: Caps, silve

10、r or bright alloy plate; leads solder coated. Strength: 7 pounds along terminal axis.

Voltage rating: See table I.

11、Current-carrying capacity: 100 percent at +25 C; 110 percent at -55 C; 80 percent at +125 C. The temperature of the case, body, or terminals, at no point, shall rise more than 70 C above the ambient air temperature. For 10 and 15 ampere fuses, the maximum temperature rise shall be 85 C. Resistance:

12、See table I. Cold resistance is measured at 10 percent or less of rated current. Overload interrupt: Percentage of nominal rating, interrupt time -55 C through +125 C, 200 percent in 0 to 5 seconds; 300 percent in 0 to 0.1 second. Interrupt time for 15 ampere fuse shall be 10 seconds maximum at 200

13、percent of rated current and 0.3 second maximum at 300 percent of rated current. Short circuit interrupt: 300 amperes at maximum voltage dc. Fifty amperes at a power factor of 1.0 at maximum voltage ac. Shock: Method I. Thermal shock: Method 107, MIL-STD-202, test condition B. Marking: Fuses shall b
