coffee maker test:
1.Power Input
The power input to an appliance shall not be more than 105 or less than 90 percent of its marked rating.
2.Leakage Current Test
not be more than:
a) 0.5 mA for an ungrounded (2-wire) appliance,
b) 0.5 mA for a grounded (3-wire) appliance that is easily carried or conveyed by hand, and
c) 0.75 mA for a grounded (3-wire) permanently connected appliance, or a cord connected appliance that is intended to be fastened in place or located in a dedicated space and employing a standard attachment plug rated 20 A or less.
3.Resistance of Grounding Test
The resistance between the point of connection of the equipment-grounding means at or within the appliance and any other point in the grounding circuit of the appliance shall not exceed 0.1 ohms.
4.Operational Tests
5.Normal Temperature Tests
6.Leakage Current as a Result of Moisture Tests
7.Dielectric Voltage-Withstand Test
An appliance shall be capable of withstanding for 1 min without an indication of unacceptable performance, the application of a potential applied between live parts and accessible metal parts. The appliance is to be at its maximum normal operating temperature. The test potential shall be 1000 V.
8.Broken Element Test
9.Strain Relief Test
The strain-relief means provided on an attached flexible cord, shall be capable of withstanding for 1 min, without displacement, a pull of 35 lbf (156 N) applied to the cord, with the connections within the appliance disconnected.
10.Metal Enclosure Impact Tests
Each of three samples of the appliance is to be subjected to one impact. This impact is to beimparted by dropping or swinging a 2-inch (50.8-mm) diameter steel sphere, weighing 1.18 lbf (0.535 kg) from a height that will produce an impact of 1.5 ft-lbf (2.03 J). The sample is to be rigidly supported and the impact is to be made perpendicular to the most vulnerable spots on the appliance enclosure that are exposed to a blow during intended use.
11.Thermal Degradation
12.Handle Securement Tests
13.Loading Test
14.Abnormal Operation Tests
15.Automatic Controls Test
16.Permanence of Marking Tests |
