This European Standard was approved by CENELEC on 2004-05-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

Foreword
The text of document 37/298/FDIS, future edition 2 of IEC 60099-4, prepared by IEC TC 37, Surge
arresters, was submitted to the IEC-CENELEC parallel vote. Together with the common modifications
prepared by the CENELEC Reporting Secretariat SR 37 for amendment A2:2002 to EN 60099-4:1993, it
was approved by CENELEC as EN 60099-4 on 2004-05-01.
This European Standard supersedes EN 60099-4:1993 + A1:1998 + A2:2002.
This European Standard includes the following significant editorial changes with respect to the previous
edition.
– Clauses 1, 2 and 3 contain common subclauses that cover all arrester types. Clauses 4 to 9 contain
subclauses that apply to porcelain-housed arresters. To a great extent, the content of Clauses 4 to 9
also applies to arrester types other than porcelain-housed. Any exceptions that apply to polymer-
housed, GIS, separable and dead-front, and liquid-immersed arresters are included in Clauses 10 to
13 as entire subclauses, not as parts of subclauses. That is, if any subclause of Clauses 4 to 9 does
not apply in its entirety to a particular type of arrester, then a replacement subclause is given in its
entirety in the appropriate Clauses 10, 11, 12, or 13. This avoids the necessity for the user of the
document to judge which part of a clause has been amended.
– Table 1 has been modified. The previous Table 1 included references to subclauses for type testing.
Such references are really not appropriate in Clause 4 and have been transferred to a new table in
Clause 8.
– Clauses 6, 8, 11, 12 and 13: modifications have been made to short-circuit requirements.
– Requirements of Clause 13 (mechanical considerations) have been incorporated into Clauses 5, 6, 8,
10, 11, 12 and 13, and Annex A of this new edition.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-05-01
Annexes ZA and ZB have been added by CENELEC.
