CEマーク
Identifying which directive(s) may be applicable, as there may be more than one, involves a simple exercise of reading the scope of each directive to establish which apply to the product (Such as the "Low Voltage Directive," 2014/35/EU). If the product does not fall within the scope of any of the sectoral directives, then the product does not need to bear CE marking (and, indeed, must not bear CE marking).
