Are components covered by the LVD?
Sometimes. The Commission LVD Guide says the directive's scope generally includes electrical equipment intended for incorporation into other equipment as well as equipment used directly. That means an item does not leave LVD scope merely because it will be built into a larger product.
The important exception is for basic components whose safety depends, to a very large extent, on how they are integrated into the final product and for which a risk assessment cannot be undertaken on the component alone. The guide gives examples such as active electronic components, passive components, and some electromechanical components. Those basic components are not covered as such by the LVD and should not carry CE marking for the LVD unless another applicable Union law requires CE marking.
By contrast, other electrical components intended for incorporation can be covered as LVD equipment when their own risk assessment can be made. The guide names transformers and electrical motors as examples, while noting that safety aspects of incorporation into the final product normally still need further assessment.
- Treat bare electronic parts such as resistors, capacitors, integrated circuits, connectors, relays for printed circuit boards, and micro switches as potential basic components, then check whether their safety can be assessed without the host product.
- Treat assessable electrical items such as transformers, motors, appliance couplers, cables, cord sets, and certain adapters as candidates for LVD coverage when they are designed for the LVD voltage ranges and are not excluded.
- Do not use a supplier's CE mark or absence of a CE mark as the whole answer; first determine whether the item is LVD equipment in its own right or only a basic component for integration.
