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.
