Underwriters Laboratories has a web site, and you definitely need to
visit it and also call them. To get your product UL approved .... which
will go a long way towards resolving insurance issues ..... you will
have to go through their licensing process. I worked for a company
making ceramic lamps, and each lamp had to have UL approved parts, and
had to pass a cord pull test. Each lamp type had to be completed, then a
sample tested by dropping the lamp from a certain height so that the
entire load of the falling lamp was caught by the attach point of the
cord on the lamp before the lamp hit the floor. If their was no tearing
and nothing pulled loose, the license was granted, and a label issued
for each lamp. Of course we had to pay for each label. This is a money
maker for UL., but that is how it works.
But, it is a must if you really want to avoid potential problems.

Hi John,
The 'Cord Pull' is a good thing for knowing about if one is
doing new or replacement Cords for their own lamps,
appliances or devices as well.
Tell us how it is done, will you?
Also, do you recall the cost-per-label of the "U.L.Approved"
decals or stickers?
Best wishes,
Phil

The test is a "drop" test, not a very sophisticated test, but must be
done in front of the appropriate UL inspector.
The plug end of the cord of the lamp is secured, and the lamp placed at
a sufficient height off the floor on a counter, so as not to strike the
floor during the test. The lamp is simply pushed off the edge of the
counter. The test is designed to see if ordinary home type accident
would result in any kind of failure and pose a saftey concern. If the
cord breaks, pulls out of the lamp, or otherwise strains or puts a load
on any of the electrical parts in the chain, then the test is a failure,
and no certification issued. Adjustments in the cord are made
accordingly to eventually accomodate the test and get satisfactory
result. Most of the time, after one understands the parameters of the
test, the lamp maker does whatever is necessary to ensure the test is
passed, and then it just becomes a matter of demonstrating that
materials and assembly procedures meet the standards of the test. Once
materials, assembly procedures, and product are certified, then mass
production can proceed, and the appropriate UL label attached.
Hope this helps.
