National foreword

This British Standard has been prepared by Technical Committee CPL/61 and is

the English version of EN 50106:1997 Safety of household and similar electrical

appliances — Particular rules for routine tests referring to appliances under the scope of EN 60335-1 and EN 60967, including amendments A1:1998 and

A2:2001, published by the European Committee for Electrotechnical Standardization (CENELEC)

The foreword of EN 50106 makes reference to the date of withdrawal, dow, of the relevant national standard In this case there is no national standard

This British Standard is to be read in conjunction with BS EN 60335-1:1995

Safety of household and similar electrical appliances — Part 1: General requirements, and BS EN 60967:1991 Specification for safety of electrically heated blankets, pads and similar flexible heating appliances for household use The

many references to Part 1 should be read as references to BS EN 60335-1:1995, which is the English language version of EN 60335-1:1994 which was derived from IEC publication 335-1, third edition 1991, second impression 1993

Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part 1

The start and finish of text introduced or altered by amendment is indicated in the text by tags  Tags indicating changes to IEC text carry the number of the IEC amendment For example, text altered by IEC amendment 2 is indicated

by 

Product approval Attention is drawn to the fact that products conforming to

this British Standard may be approved by the British Electrotechnical Association Approvals Board for the purposes of participation in the CENELEC Certification Agreement and in the CB Scheme of IECEE (Details of the BEAB Approvals Marks Scheme are given on the inside back cover.)

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

Foreword

The proposal to transform Harmonization

Document HD 289 S1:1990 including its

amendment A1:1992 into a European Standard,

document CLC/TC 61(SEC)858, was circulated in

July 1992

meeting in September 1992 when it was decided to

submit a draft for EN 50106 to the voting procedure

This decision was modified during the El Campello

meeting in October 1993 when it was decided to

submit a new draft to the unique acceptance

procedure (UAP) The procedure started in

October 1994 but due to the number of comments

received, the draft was rediscussed during the

Dublin meeting in May 1995 when it was decided to

submit a revised draft to the formal vote

This draft was circulated in March 1996 and was

ratified by CENELEC as EN 50106 on 1996-10-01

This European Standard has been prepared by the

secretariat of CENELEC Technical Committee

TC 61

For products which have complied with

HD 289 S1:1990 and its amendment A1:1992

before 1999-04-01, as shown by the manufacturer or

by a certification body, this previous standard may

continue to apply for production until 2004-04-01

Section 1 General tests

1.1 Earth continuity test 5

1.2 Electric strength test 5

Section 2 Standard sheets

Introduction

The tests detailed in this standard are carried out by the manufacturer and apply to products within the

scope of EN 60335-1 and EN 60967

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

EN 50106:1997

1.1 Earth continuity test

For Class I appliances, a current of at least 10 A derived from a source having a no-load voltage not

exceeding 12 V, is passed between each of the accessible earthed metal parts and

— the earthing pin or earthing contact of the plug;

— the earthing terminal, for appliances intended to be permanently connected to fixed wiring;

— the earthing pin of the appliance inlet

The voltage drop is measured and the resistance is calculated from the current and voltage drop

NOTE 1 The test is only carried out for the duration necessary for the measurement to be made.

The resistance shall not exceed

— 0,2 % for appliances having a supply cord;

— 0,1 % for other appliances

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.

NOTE 3 For appliances having a long supply cord the resistance may exceed 0,2 % but it is not to exceed the sum of the resistance

of the supply cord and 0,1 %.

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 (r.m.s.) and the points of application are shown in the following table

No breakdown shall occur

NOTE 1 The circuit used for the test incorporates a current sensing device which trips when the current exceeds 5 mA However, it may be necessary to set the device to trip at a higher value which is not to exceed 30 mA Tripping of the device indicates breakdown

by audible or visual means The high voltage transformer is to be capable of maintaining the specified voltage until the tripping

current flows.

NOTE 2 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 the table An a.c voltage having a frequency up to 5 Hz is considered to be a d.c voltage.

1.3 Functional test

The functioning of a component is checked by inspection or an appropriate test if its malfunction could

result in a hazard

NOTE Verifying the correct direction of rotation of motors and the appropriate operation of switches and controls are examples of checks which may be necessary.
