BS EN 50106:2008EN 50106:2008 2 Foreword This European Standard was prepared by the Technical Committee CENELEC TC
12、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 6
13、1(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
14、 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) 20
15、09-06-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-06-01 _ BS EN 50106:2008 3 EN 50106:2008 Introduction The tests detailed in this standard are carried out by the manufacturer and apply to products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
16、 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 manuf
17、acturer 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 proc
18、edure 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 t
19、o 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
20、 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. BS EN 50106:2008EN 50106:2008 4 SECTION 1 - GENERAL TESTS 1.1 Earth continuit
21、y 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
22、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 , or 0,1 plus the resistance of the supply cord, for other appliances, 0,
23、1 . 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 streng
24、th 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. Table 1 Test voltages Points of application Test voltag
25、e V Class I appliances and class II appliances Class III appliances Rated voltage 150 V 150 V Between live parts and accessible metal parts separated from live parts by basic insulation only 800 1 000 400 double or reinforced insulation a2 000 2 500 a For class I appliances, this test does not need
26、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 rela
27、y. BS EN 50106:2008 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 sens
28、ing 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
29、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 Exa
30、mples 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.

37、ing at safety extra-low voltage. The test voltage is determined from Table 101. Table 101 Test voltages Type of test voltage Test voltage V Rated voltage 150 150 and 250 a.c. 2 000 + X 2 500 + X d.c. 3 000 + X 3 750 + X The value of X is determined as follows. The flexible part is opened and the ins
38、ulation of the heating element is removed over a length of 5 mm to expose the conductor. The heating element is then reinserted into the enclosure of the flexible part. A test voltage of 1 000 V (1 500 V d.c.) is applied between the conductor and the external surface of the flexible part. The voltag
39、e is increased in steps of 500 V (750 V d.c.) until breakdown occurs. The value of X is the test voltage before breakdown occurs. NOTE 101 If the flexible part incorporates a permanent outer enclosure made of electrical insulating material such as PVC, the value of X is determined with this enclosur
40、e removed. NOTE 102 Acceptable methods of applying the test voltage are passing the flexible part between rollers; passing the flexible part on a conveyor by a metal plate; placing the flexible part between metal plates; sweeping a chain wire brush over the flexible part. 1.3 Functional test Additio
41、n: The functional test includes a check that the resistance of the heating element is within the tolerance; a check that no current flows when the control is in the off position. NOTE 101 The tolerance selected is to ensure that the power input deviation of Clause 10 is not exceeded. BS EN 50106:200

Addition: 2.1 Construction The water container is subjected to a pressure test using a fluid. When a liqui
43、d is used, the pressure is for closed water heaters, 0,7 MPa for those having a rated pressure not greater than 0,6 MPa, and 1,1 times rated pressure for others; for cistern-fed water heaters and low-pressure water heaters, 1,1 times rated pressure; for open-outlet water heaters, 0,05 MPa; for ciste
44、rn-type water heaters, 0,03 MPa. When gas is used, these pressures may be reduced but are to be sufficient to reveal leakage. NOTE Care should be taken when testing closed water heaters with gas. Leakage of the fluid is not to occur during the test. _ A-deviation: National deviation due to regulatio

49、owave power control adjusted to the highest setting. The energy flux density of microwave leakage is measured at any point approximately 50 mm from the external surface of the appliance. An appropriate load may be used. The measuring instrument is moved over the external surface of the oven and the microwave leakage measured. The microwave leakage shall not exceed 50 W/m.
