Rub test on the label
Label requirements for electronic products should include model numbers voltage information, safety warnings, and regulatory compliance symbols.These labels should be tested with a rub test.
Fatigue test for LED lighting
A fatigue test is done in order to check how well a functional part will do after being used multiple times. The inspector will use the part as it is meant to be used, anywhere from 20 to 50 times depending on time limits.
Assembly check for LED products
To ensure that your customers can easily assemble, install and use your product, an on-site assembly check is vital. The inspector will put together the product following the assembly instructions, with regular tools or tools that come with the product when purchased.
Torque test for lighting components
Torque testing is a type of quality assurance test used for products with rotating parts, such as screws and bolts. It measures the rotational force required to turn these parts and helps identify any potential quality issues with them.
Hi-potential test for compliance with safety standards
The hi-potential test, or dielectric voltage-withstand test, measures the electrical current coursing through a product's insulation. By conducting this type of test, you can discover any issues with current leakage or dielectric breakdowns. To do so, simply have an inspector check for signs of either Current Leakage or Dielectric Breakdowns.
Function test for lighting
The inspector will check the product’s functions, such as turning the light on and off, checking proper illumination, and confirming the light dims properly (if relevant), among other things. The inspector should report any functional issues observed during testing, as well as any deviances from your instruction manual and specifications.
Endurance testing
The function of an endurance test is to safety assess and observe the functional performance of lighting products over an extensive period of time. The light should be left on at its highest setting for four hours straight while the inspector periodically observes it for any malfunctions.
Internal check against a component data form
A certified component data form (CDF) is a table of critical components and your approved manufacturers of those components that you or your supplier should provide the inspector. The inspector can compare the components in your actual product against the CDF and report any non-conformities.
Drop test
A drop test is necessary for shelf-mounted luminaires under the UL 153 standard. It’s also required for luminaires intended for use in hazardous conditions under the UL 844 standard. The inspector drops a shelf-mounted unit from a height of 3 feet (91.4 cm) onto tissue paper covering a nominal 1/2 inch (12.7 mm) thick, knot-free softwood sheet that rests on concrete flooring.
Lighting source/integrating sphere test
Brightness, color or efficiency standards are tested with an integrating sphere test that can measure the lighting source using common metrics. This test requires an integrating sphere system with a spectroradiometer for spectral mismatch corrections and computing software. Most lighting manufacturers should have both the equipment and related software available on site already, as they’re essential for LED lighting manufacturing. Reporting is done compared to your spec.
Electromagnetic compatibility (EMC) test
Electromagnetic compatibility (EMC) lighting testing helps ensure your LED light doesn't emit excessive electromagnetic interference during use. High electromagnetic interference can disrupt or damage other electronics.
