All safety critical components must comply with the applicable component safety standard. This is a general requirement included in all safety standards = UL, CSA, EN, & IEC. Wiring evaluated to the appropriate wire standard, cabling evaluated to the appropriate cable standard, etc. Plastics, connectors, switches, fuses, power supplies, transformers, EMI filters, motors, ballasts, drivers, batteries, battery packs, etc.
Every component that puts your product in compliance with any clause in any of the applicable safety standards is a “safety critical component” (shock hazards, fire hazards, energy hazards, injury hazards, chemical hazards, & radiation hazards). Every safety critical component must meet its component safety standard - isolating devices, enclosure materials, insulating materials, power supplies, batteries, etc. This helps explain why there are over 600 UL standards.
Certified Component Considerations
In general, when sourcing safety critical components, you should ask your vendor for a
UL/CSA/CE certified part.
Uncertified Components – Your Options
The same options apply for all uncertified safety critical components - you can either:
Uncertified Component Review Considerations
We advise all of our customers to avoid uncertified components. However, if there are no commercially available certified components that fit your need, you may have no choice but to have the component certified as part of your overall product. Before choosing this path, you should consider:
