Subject: Aquarium- and table fountain pumps with PVC power cord
Reference:
Standard, section
law, directive    EN 60335-2-41


Question: For those pumps no special cables are required in EN 60335-2-
41. Can therefore PVC cables be used as listed in EN 60335-1,
clause 25.7 e.g. H03VV-F (60227 IEC 52) or H05VV-F (60227
IEC 53)?

Proposal of
solution: For aquarium pumps and table fountain pumps PVC cords with
properties at least equal to H03VV-F (60227 IEC 52) or H05VV F
(60227 IEC 53), may be used, for which the proof of permanent
water resistance according to DIN EN 50525-2-21 Appendix D
and E was performed. As requirement of the mechanical
properties of the values for the tensile strength and elongation at
break according to DIN EN 50363-4-1 shall be used. As a
reference for water immersion, the values are used in Table 2
(compound TM2) "After aging in air oven."
Thus, the decision EK1 561-13 is replaced


Reason: Neither in H03VV-F (60227 IEC 52), nor in H05VV-F (60227 IEC
53) appropriate requirements for permanent water-resistance are
currently defined: Despite the many years use of PVC cables in
such pumps no safety problems have been known. The AK
511.11.6. has determined to apply the test methods described in
DIN EN 50525-2-21:2012-01 Appendix D and E, as evidence of
permanent water resistance of the connecting cables of
aquariums and indoor fountain pumps.

Decision Proposal of solution is accepted 2014-04-15.
For implement the category C according to AD 06 is
essential.
