each fuse shall be marked in accordance with method I of MIL-STD-1285 with the following:
a. Style (see 1.2.1.1).
b. Characteristic (see 1.2.1.2).

between the soldered items may be determined by visual examination. There shall be no evidence of "cold
soldering" and the use of excessive amounts of solder will not be permitted.
3.16 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
