This European Standard was approved by CENELEC on 2008-06-01. 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.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 61, Safety of
household and similar electrical appliances.
During the Brughes meeting of CENELEC TC 61 in June 2005, document 61(SEC)1506 was discussed
and it was decided to prepare a new edition of EN 50106 and send it to the voting procedure. Two
additional proposals, documents 61(BE)0003/NP and 61(DE)0587/NP, were discussed during the
Brussels meeting in November 2005, where it was decided to include them in prEN 50106. Another
proposal, document 61(DE)0588/NP, was included as a result of the Malaga meeting in June 2006.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as EN 50106 on 2008-06-01.
This European Standard supersedes EN 50106:1997 + A1:1998 + A2:2001.
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) 2009-06-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-06-01

Introduction
The tests detailed in this standard are carried out by the manufacturer and apply to products within the
scope of EN 60335-1.
These tests are intended to reveal a variation during the manufacture of appliances which could impair
safety. They do not impair the properties and the reliability of the appliance and are to be carried out on
each appliance. They are normally carried out on the complete appliance after assembly but the
manufacturer may perform the tests at an appropriate stage during production, provided later
manufacturing operations would not affect the results.
NOTE Components are not subjected to these routine tests if they have been previously checked by suitable routine tests.
The manufacturer may use a test procedure which is better suited to his production arrangements
provided that appliances which withstand those tests have at least the same degree of safety as
appliances that withstand the tests specified in this standard.
The routine tests listed in this standard are the minimum considered necessary to cover essential safety
aspects. It is the responsibility of the manufacturer to decide if additional routine tests are necessary.
It may be determined from engineering considerations that some of the tests required in this standard are
impracticable or inappropriate and therefore unnecessary.
If a product fails any of the tests, it is subjected to all of the tests after repair and/or adjustment.
There are no additional requirements for particular appliances unless stated in the relevant standard
sheet of Section 2.
SECTION 1 - GENERAL TESTS
1.1 Earth continuity test
A current of at least 10 A, derived from a source having a no-load voltage not exceeding 12 V (a.c. or
d.c.), is passed between each of the accessible earthed metal parts and
– for class I appliances intended to be permanently connected to fixed wiring, the earthing terminal;
– for other class I appliances,
• the earthing pin or earthing contact of the plug;
• the earthing pin of the appliance inlet.
The voltage drop is measured and the resistance is calculated and shall not exceed
– for appliances having a supply cord, 0,2 Ω, or 0,1 Ω plus the resistance of the supply cord,
– for other appliances, 0,1 Ω.
NOTE 1 The test is only carried out for the duration necessary to enable the voltage drop to be measured.
NOTE 2 Care is to be taken to ensure that the contact resistance between the tip of the measuring probe and the metal
part under test does not influence the test results.
1.2 Electric strength test
The insulation of the appliance is subjected to a voltage of substantially sinusoidal waveform having a
frequency of approximately 50 Hz or 60 Hz for 1 s. The value of the test voltage and the points of
application are shown in Table 1.

For class I appliances, this test does not need to be carried out on parts of class II construction if the test is considered to be
inappropriate.
NOTE 1  It may be necessary for the appliance to be in operation during the test to ensure that the test voltage is applied to
all relevant insulation, for example, heating elements controlled by a relay.

– 5 – EN 50106:2008
No breakdown shall occur. Breakdown is assumed to occur when the current in the test circuit exceeds
5 mA. However, this limit may be increased up to 30 mA for appliances with a high leakage current.
NOTE 2 The circuit used for the test incorporates a current sensing device that trips when the current exceeds the limit.
NOTE 3 The high voltage transformer is to be capable of maintaining the specified voltage at the limiting current.
NOTE 4 Instead of being subjected to an a.c. voltage, the insulation may be subjected to a d.c. voltage of 1,5 times the
value shown in Table 1. An a.c. voltage having a frequency up to 5 Hz is considered to be a d.c. voltage.
1.3 Functional test
The correct functioning of an appliance is checked by inspection or by an appropriate test if the incorrect
connection or adjustment of components has safety implications.
NOTE Examples are verification of the correct direction of motor rotation and the appropriate operation of interlock
switches. This does not require testing of thermal controls or protective devices.
