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 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 ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ © BSI 22 November 2001 EN 50106:1997 Section General tests 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 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 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 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 s The value of the test voltage (r.m.s.) and the points of application are shown in the following table Points of application Test voltage V ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Class I appliances Between live parts and accessible metal parts separated from live parts by — basic insulation only 000 — double or reinforced insulation 500 Between live parts and metal parts separated from live parts by basic insulation onlya a Class II appliances 500 Class III appliances 400 000 This test may be carried out on components during assembly No breakdown shall occur NOTE The circuit used for the test incorporates a current sensing device which trips when the current exceeds 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 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 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 © BSI 22 November 2001 ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ blank EN 50106:1997 Section Standard sheets These standard sheets state additional routine

500 + X) V unless the test is carried out with d.c., in which case it is (3 500 + X) V The value of X is determined as follows The insulation of the heating element is removed over a length of mm to expose the conductor The heating element is inserted into the enclosure of the flexible part A test voltage of 000 V (1 500 V DC) is applied between the conductor and the external surface of the flexible part The voltage is increased in steps of 500 V (700 V DC) until breakdown occurs The value of the breakdown voltage is the value X NOTE 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 enclosure removed NOTE Acceptable methods of applying the test voltage are: — passing the flexible part between rollers; — passing the flexible part on a conveyor over a steel plate; — placing the flexible part between metal plates; — sweeping a chain wire brush over the flexible part. 1.3 Functional test The functional test shaft include: — a check of the resistance of the heating element; — a check that no current flows when the control unit switch is in the “OFF” position
