1.1 These requirements cover special types of fuses not covered by separate requirements and that are for use in radio- and television-type appliances where they are relied upon to limit power or current, or both. These requirements also apply to holders intended to accept such special fuses, where the holder may be an integral part of the fuse design. It should be noted, however, that compliance of a special fuse with these requirements does not assure that it is acceptable for use as a protective device in the end-use product.
1.2 A special fuse is a single function (providing protection only) device intended to interrupt a current flow when the current passing through it exceeds a preselected value. It is nonrenewable, that is, the fuse element cannot be replaced after operation, but it can be multi-operational (multi-element).
1.3 The acceptability of any special fuse covered by these requirements in any particular device or appliance depends upon its effectiveness in continued use under the conditions that prevail in actual service. Accordingly, for a particular application, the special fuse may be affected by the requirements for the device or appliance in question, and it may be necessary to employ protective devices having features other than, or in addition to, those specified in these requirements.
