Amend the third paragraph of Clause
2.10.3.1 to be:
These requirements apply for equipment to
be operated up to 2000 m above sea
level.Forequipment to be operated at more
than 2000 m above sea level and up to
5000m above sea level, the minimum
CLEARANCE shall be multiplied by the
factor 1.48 corresponding altitude of 5000m
given in Table A.2 of IEC 60664-
1.Forequipment to be operated at more
than 5000 m above sea level, the minimum
CLEARANCE shall be multiplied by the
factor given in Table A.2 of IEC 60664-
1.Linear interpolation ispermitted between
the nearest two points in Table A.2. The
calculated minimum CLEARANCEusing
this multiplication factor shall be rounded
up to the next higher 0,1 mm increment.

20000.2, when quoting an entire
international standard in the normative
quoting files and reference documents of
Annex P of this part, the principles of
quotation are as follows:
- If there is no national standard or industry
standard corresponding to the international
standard, then the international standard is
quoted;
- If there is national standard or industry
standard corresponding to the international
standard, then either the national or
industry standard is quoted;
- If the date of the national standard or
industry standard is not given, the latest
edition of the standard applies;
- The national standard or industry
standard number, corresponding
international standard number and the
consistency level code should be identified
in parentheses behind the listed national
standard or industry standard.
When quoting several chapters or clauses
of the international standard, the principles
of quotation are as follows:
- If there is no national standard or industry
standard corresponding to the international
standard, then the international standard is
quoted;
