The scope of EN 61008-1 and EN 61008-2-1 or EN 61009-1 and EN 61009-2-
1 applies with the following additions.
"This standard specifies requirements and tests for Type F and Type B RCDs
(Residual current devices). Requirements and tests given in this standard are
in addition to the requirements of Type A residual current devices according
to EN 61008-2-1 or EN 61009-2-1. This standard can only be used together
with EN 61008-1 and EN 61009-1."
1 In third paragraph, delete “with rated frequency 50 Hz or 60 Hz”.
1 In sixth paragraph, replace “IEC” with “EN”.
1 Add a new paragraph after fourth paragraph:
"Type F and type B RCDs have high resistance against unwanted tripping
even if the surge voltage causes a flashover and a follow-on current occurs
and in case of inrush residual currents with a maximum duration of 10 ms
which can occur in case of switching ON electronic equipment or EMC-
filters."
1 Delete the seventh paragraph.
1 Modify note 2 by:
“Note 2 : deleted”
2 Replace the contents of Clause 2 with: “Normative references to
international publications are listed in Annex ZA.”

The maximum break time shall not exceed 0,3 s for general type RCDs and
for S-type RCDs the maximum break time shall not exceed 0,5 s.
9.2.1.7.1 Add a note after the first paragraph in 9.2.1.7.1 :
Note: The open circuit voltage of the DC source should be high enough to guarantee
stable smooth d.c. current (e.g. more than 24 V).
9.2.2 Delete the paragraph before the note.
