EN/IEC 60950-1:2006/A2:2013 amendment has a designated Transition Period (Date of Withdraw (DoW)) listing of 2016-07-02.
Since March 01, 2013, there have been two options for your company to apply for TÜV SÜD Certificates as listed below.
Option 1: IEC 60950-1:2005 + A1:2009, and; EN 60950-1:2006 + A11:2009 + A1:2010 + A12:2011
Option 2: IEC 60950-1:2005 + A1:2009 + A2:2013, and; EN 60950-1:2006 + A11:2009 + A1:2010 + A12:2011 + A2:2013
After July 02, 2016 only Option 2 is available for standard EN/IEC 60950-1.
Start early to include Amendment A2 in your certified products to help prevent shipment delays into the European Union economic area your company.

1. DOR (date f ratification) = date the CENELEC Technical Board notes the approval of an EN or HD, from which time the standard may be said to be adopted.
2. DAV (date of availability) = date when the definitive text in the official language versions of an approved EN or HD is distributed by the CENELEC Central Secretariat.
3 DOA (date of announcement) = latest date by which the existence of an EN or HD has to be announced at national level by the CENELEC members.
4. DOP (date of publication) = latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement.
5. DOW (date of withdrawal) = latest date by which national standards conflicting with an EN or HD have to be withdrawn
Amendment No. 2 to EN/IEC 60950-1:2005 Second Edition, Safety of Information Technology Equipment, was published in 2013-05-28. The differences as compared to Amendment 1 (and IEC/EN/UL/CSA…60950-1 2nd Edition) are mostly minor, but there are a few notable changes.
Endorsement notice: The corresponding European regulatory standards EN/IEC 60950-1:2006/A2: 2013 was approved by CENELEC with agreed common modifications as announced (DoA) on 2014-01-02, and it was formally published (DoP) 2014-07-02 by EU countries for replacing previous versions used in certification by their withdraw (DoW) on 2016-07-02.
IEC/EN/UL/CSA…60950-1 2Ed, Amendment 2 included these important modifications:
- Modifies the definition of rated voltage (220.127.116.11)
- Modifies the requirements for evaluation and testing of components (1.5.2)
- Modifies the requirements for capacitors bridging insulation (1.5.6)
- Modifies the requirements for bridging of basic insulation by a VDR (18.104.22.168)
- Adds the requirements for use of graphical symbols (22.214.171.124)
- Modifies the requirements for SELV voltages under fault conditions (2.2.3)
- Adds the requirements for the relevant symbols of functional earthing (2.6.2)
- Modifies the requirements for humidity conditioning test (2.9.2)
- Modifies the requirements for examples of application of insulation (Table 2H)
- Modifies the requirements for additional clearances in primary circuits (Table 2L)
- Modifies the requirements for AC power supply cords (126.96.36.199)
- Modifies the requirements for sizes of terminals for mains supply conductors and protective earthing conductors (Table 3E)
- Modifies the requirements for stability test (4.1)
Clause 4 (Physical Requirements)
- Adds and modifies the relevant requirements for batteries (4.3.8)
Sub-clause 4.3.8 (Batteries) now includes a reference to IEC/EN 62133 for portable secondary sealed cells and batteries (other than button) containing alkaline or other non-acid electrolyte, which includes Lithium-Ion. Also, the criteria for overcharging of a rechargeable battery were modified to reflect some of the work done on IEC/EN 62368-1 to make a more realistic test condition.
The new IEC/EN 62133 requirement could have a considerable negative impact on manufacturers who were able to use IEC 60950-1 for such batteries in the past, although it is muted by the existing U.S. and Canada National Difference requiring UL 2054 for most of these same types of batteries.
- Modifies the requirements for test voltages for electric strength tests based on required withstand voltages (Table 5C)
Clause 7 (Connection to Cable Distribution Systems)
- Adds the relevant requirements for impulse test (7.4.3)
Sub-clause 7.4.1 (General) now allows for similar protection of TNV-1 circuits as is currently allowed in 7.3, and therefore such circuits do not need to be subjected to voltage surge test in 7.4.2 or impulse test in 7.4.3.
This change provides additional design options for equipment connected to the cable distribution network and involving SELV voltage levels and that are intended to be earthed on the secondary side.
Annex Q – Voltage Dependent Resistors (VDRs)
- Modifies the relevant requirements for VDRs (Annex Q)
Annex Q was updated to include additional information that was added to Edition No. 2 of IEC 62368-1.
Because the previous Annex Q was lacking detail, there may be a negative impact on manufacturers who previously specified VDRs that do not meet the updated criteria. There still remains some uncertainty on the true impact of this change at this time, including the provision for flammability of the VDR body.
- Modifies the relevant requirements for insulated winding wires for use without interleaved insulation (Annex U)
- Modifies the requirements for the evaluation of integrated circuit (IC) current limiters (Annex CC)
Note that IEC Technical Committee (TC) 108 made a commitment to limit revisions to IEC 60950-1 and concentrate its work and effort on IEC 62368-1, Audio/Video, Information and Communication Technology Equipment – Part 1: Safety requirements. The Standard will eventually replace IEC 60065 (AV Equipment) and IEC 60950-1 (ICT Equipment). Therefore, most of the Amendment 2 changes were adopted to allow for continued effective application of IEC 60950-1 during the transition.
