各位高手,請問60335-1中的19章的subclause 19.5非正常測試的目的何在?
19.5 The test of 19.4 is repeated on class 0I appliances and class I appliances
incorporating tubular sheathed or embedded heating elements. However, controls are not
short-circuited but one end of the element is connected to the sheath of the heating element.
This test is repeated with the polarity of the supply to the appliance reversed and with the
other end of the element connected to the sheath.
