Low-voltage fuses -- Part 3-1: Supplementary requirements for fuses for use by unskilled persons (fuses mainly for household and similar applications) -- Sections I to IV: Examples of types of standardized fuses

Gives a comprehensive description of the mechanical and electrical characteristics of fuses for household and similar applications and of the relevant tests. Describes six types of standardized fuses: D types fuses; cylindrical fuses (types A, B, C); pin-type fuses; cylindrical fuse links (primarily used in plugs). This new publication is of equal interest to the manufacturer and to the user of fuses namely for household and similar applications.

The following dates were fixed:

- latest date by which the existence of the HD
 has to be announced at national level (doa) 2005-05-01

- latest date by which the HD has to be implemented
 at national level by publication of a harmonized
 national standard or by endorsement (dop) 2005-11-01
