MIL-STD-1285, and either 3.14.1 or 3.14.2, or a combination of both.

3.14.1 Ferrule and end cap marking. When fuse ferrules and end caps are marked, the marking shall include the

following:

a. PIN designation (see 1.2.1).

b. Manufacturer's name, trademark, or code symbol.

3.14.2 Labels. When fuse labels are used, the following shall apply.

3.14.2.1 Material. Label material used shall enable the fuses to meet the performance requirements of

this specification and shall show no evidence of peeling, wrinkling, ends lifting, or illegible ink markings (see

4.7.9.1). For guidance on label material, see 6.3.7.

3.14.2.2 Information. Fuse marking shall include the information shown in the following example:

Manufacturer's symbol

The manufacturer's identification may be shown on the printed label or may be

stamped on the fuse ferrule (or both).

The print size shall be the largest possible which will permit all of the required information to appear on the label.

3.14.2.3 Label size. The width of the label for fuses 2 inches (50.8 mm) in length or less shall almost touch the

fuse ferrule on each end of the fuse. For fuses more than 2 inches (50.8 mm) in length, the label shall be large

enough so that the markings will be legible. The label shall be centered on the fuse. The label shall completely wrap

around the fuse body between the ferrules. Overlapping of the label upon itself is permitted, provided it does not

overlap any of the printed information. For fuses not greater than .406 inch (10.3124 mm) diameter, the printed

information shall run the length of the fuse body from ferrule to ferrule. For other fuse sizes, the printed information

may run perpendicular to the fuse length.
