Schedule of limitations.
1) The fuse must be so mounted that creepage and clearance distances meet the
requirements of Table 2 of EN50020 :1977 or Table 4 of EN50020 :1994 (equivalent to
IEC 60079-11 4th Edition 1999).
2) When used in intrinsically safe apparatus it will be necessary to determine a surface
temperature classification for the fuse.
