For those of us engaged in cross-border e-commerce,we all know that the ce marking is a mandatory requirement for many products exported to the European Union, as it signifies that the products meet EU safety and health standards. Behind the CE certification lie multiple technical directives, among which the three most crucial ones are LVD, EMC, and RED.

LVD governs "safety", EMC governs "electromagnetic compatibility", and the RED directive is the compliance framework for radio equipment.

Different products correspond to different testing items: some only require lvd testing, some require both LVD and emc testing, and others require RED testing.

Differences Between the Three EU Directives: LVD, EMC, RED(图1)

Definitions of the Three Directives

1. ce-lvd

LVD refers to the EU low voltage directive (2014/35/EU), an important component of the CE certification system. Its key objective is to prevent harm to persons, livestock, and property caused by risks such as electric shock, fire, and mechanical injury by regulating the design and manufacture of electrical products.

Simple understanding: LVD focuses on whether the product poses electric shock or fire hazards.

2. CE-EMC

EMC refers to the electromagnetic compatibility certification under the EU Electromagnetic Compatibility Directive (2014/30/EU). It aims to ensure that electrical and electronic equipment can effectively control the electromagnetic interference (EMI) they generate in the electromagnetic environment, while also resisting external electromagnetic interference (EMS). This guarantees the normal operation of the equipment and prevents it from causing unacceptable interference to other devices.

Simple understanding: EMC focuses on whether the product interferes with other equipment and whether it is susceptible to interference from other devices.

3. CE-RED

RED stands for the EU Radio Equipment Directive, officially known as Radio Equipment Directive 2014/53/EU. This directive is a mandatory certification requirement formulated by the European Union for radio equipment, intended to ensure that radio equipment complies with unified standards in terms of safety, electromagnetic compatibility, spectrum efficiency, and network security when placed on the EU market.

Simple understanding: RED is an "exclusive compliance package" for radio equipment. It incorporates the requirements of both LVD and EMC, and additionally adds specific requirements for radio performance.
