LABORATORY TEST METHOD NO. H-14
ELECTRICAL PERSONAL GROOMING APPLIANCES
1. PURPOSE:
To evaluate the safety, workmanship, and performance
characteristics of electrical personal grooming appliances.
2. PRINCIPLE:
An appliance is tested in accordance with UL Standard #859,
Standard for Safety, Electrical Personal Grooming Appliances, for
safety. The appliance is also tested for overall performance, as
well as, clarity and accuracy of the instructions.
3. REFERENCE:
UL Standard #859, Standard for Safety, Household Electrical
Personal Grooming Appliances.
4. APPARATUS AND MATERIALS:
4.1 Leakage current meter -Simpson Model 229-2, or
equivalent.
4.2 Sinusoidal voltage output transformer -Slaughter Model
105-5OW, or equivalent.
4.3 Temperature sensor probes with digital read-out -Omega
Model 199, or equivalent.
4.4 11.3 kg (25 lbs) standard weight
4.5 Stainless steel pan, 35.5 cm (14 in.) wide, 40.6 cm (16
in.) long, and 20.3 cm (8 in.) deep
5. PROCEDURE:
5.1 Item is to be tested ''as is". Visually verify that
the UL listing number, voltage and amp or watt rating is
permanently affixed to the item itself. Also, that all care
instructions and safety warnings are provided.
5.2 User maintenance instructions: Ref: Ul 859-63.0 through
64.6 examine and determine the clarity of the instructions as it
pertains to the proper care and safe use of item by user.
5.3 Important safety instructions: Ref: UL 859-63.0 through
64.6. Vertify the required letter height and the letter type on
all safety and warning instructions.
5.4 Normal temperture test: Ref: UL 859-39.1 through 39.2.
Attach tempera- ture sensor to the heating section. Turn sample
"on" and note the time and maximum temperature rise on
the initial pre-heat cycle. Leaving the sample "on",
continue to note minimum and maximum temperatures during the
thermal protection on/off cycling periods. Allow at least 15
cycling periods. Measure temperatures on the handle, collar and
clip release at the same time with a second temperature
sensor.
5.5 Strain Relief: Ref: UL 859-43.1 through 43.2. This test
method deter- mines the internal and external secureness of the
attached power cord.
5.6 Dielectric voltage withstand test: Ref: UL 859-40.1 through
40.3 to determine the electrical insulation breakdown capacity by
introducing a high voltage sinusoidal wave form through the
circuits.
5.7 Leakage Current: Ref: UL 859-33.1 through 33.4. To detect
any leakage current above 0.5 milliamperes that could product a
potentially dangerous shock hazard to the user.
5.8 Immersion Protection: Ref: UL 859-22.1 through 22.8 and
35.1 to 35.8. To determine the ability of the item to prevent, by
automatically shutting off when dropped in water, any serious
injury or electrocution of the user.
5.9 Floor Drop Test: Ref: Ul 859-41.21 through 41.22 to
determine the ability of the item to absorb abuse and continue to
operate safety for the user.
6. REPORT
Report the test results in terms of whether the appliance
tested meets or fails to meet (pass/fail) the respective UL
requirements. Also report performance under actual use test, as
well as, clarity and accuracy of the instructions.
