BS 5131 SATRA TM20 TM21 Heel Impact Fatigue Test Machine
High-heeled Shoes Impact Resistance Tester
Main purpose
The equipment used to test the continuous impact resistance index
of the heels of women's high-heeled shoes and mid-heeled shoes. The
heel impact fatigue tester is manufactured in accordance with the
specifications and is specifically designed to test the number of
continuous impact times of the heels of women's high-heeled shoes
and mid-heeled shoes.
Under certain energy and frequency conditions, this machine
continuously strikes the heel with force, until the heel breaks due
to fatigue. This is done to determine the index of the heel's
ability to withstand continuous stress and to assess the durability
of the heel.
Reference standard
BS 5131, SATRA TM20, SATRA TM21, QB/T 2864, etc.
Testing method
1. Instrument used: Shoe heel impact test machine
2. Preparation of test samples: Using a sampling method, select at
least 3 unused shoe heels for the test.
3. Test Procedures:
(1) Position the heel of the shoe within the test specimen holder
(push it all the way down), and then secure the fixing screws.
(2) Adjust the fixture base so that the center line of the shoe
heel forms a 90° angle with the impact blade. After adjustment,
lock the screws in a clockwise direction. At this point, the impact
blade should be perpendicular to the back line of the shoe heel.
(3) Rotate the adjusting screw of the shoe heel fixing seat
clockwise to adjust the height of the adjusting seat to the desired
level for the impact blade of the test piece (the impact point is
6mm below the top of the shoe heel, excluding the top layer). Then,
secure the screw.
(4) Turn on the "power" switch. According to the different
requirements of the test, set the number of tests needed. Press the
"test" button, and the hammer will continuously strike the heel of
the shoe.
(5) Once the set number of operations is reached, the machine will
automatically shut down.
(6) Examine the condition of the shoe heel damage and sort out,
record the test results.
Notes
1. Holding the heel sample: The heel sample must be securely placed
in the holder to ensure a stable position, which is necessary for
achieving more accurate testing results.
2. Do not apply any external force to the impact hammer; otherwise,
the energy of the impact will be unstable.
3. During the test, do not stand on either side of the machine to
avoid danger.
4. Before each impact, make sure to recheck that the specimen is
securely clamped; otherwise, it is likely to cause damage to the
fixture.
5. If the impact hammer is not in use, please place it in the
lowest position to prevent accidental injury and potential danger.
Maintenance and Care
1. After each test, please clean the test bench thoroughly to prevent
any debris from falling into the slide seat.
2. For each sliding position of the fixture, it is necessary to
apply oil regularly to maintain normal operation.
3. The striking hammer and the adjustment seat have been subjected
to long-term friction and sliding, so they need to be coated with
anti-rust oil.
4. When the machine is not in use, please apply anti-rust oil to
each fixture group.
5. Please regularly check whether the machine is in a horizontal
position. If there is any deviation, please immediately re-adjust
it.
