Is BS EN and IEC the same?

The field of technical standards is vast and often confusing, with multiple organizations involved in creating and enforcing these standards. In the world of electrical engineering and international product certification, two such organizations are BS EN (British Standards EN) and IEC (International Electrotechnical Commission). While both organizations play a crucial role in setting and regulating industry standards, there are significant differences between them.

Different origins and jurisdictions

BS EN, as the name suggests, is primarily focused on British standards. It is the national standardization body of the United Kingdom and has been responsible for developing and maintaining technical standards across various industries. BS EN operates under the supervision of the British Standards Institution (BSI), which ensures that the standards are aligned with UK laws and regulations.

On the other hand, IEC is an international organization that aims to develop and promote global technical standards in the field of electrotechnology. It is made up of experts from different countries who collaborate to create consensus-based standards. Unlike BS EN, the IEC does not have a specific jurisdiction and its standards are voluntary, although they are widely accepted and adopted by many countries around the world.

Scope and coverage

When it comes to scope and coverage, BS EN mainly focuses on standards related to products and services within the UK market. These standards often reflect the specific needs and requirements of the British industries and consumers. BS EN covers a wide range of sectors, including construction, manufacturing, healthcare, and information technology.

In contrast, the IEC sets global standards that apply to a broad range of electrical and electronic technologies across various industries. These standards are developed through a consensus-based approach involving experts from different countries. The IEC standards cover areas such as electrical safety, electromechanical devices, power systems, communication technologies, and renewable energy.

Enforcement and certification

BS EN standards are enforced within the UK through various means, including the BSI's certification schemes and regulatory bodies. Products and services that comply with BS EN standards receive certification marks indicating their compliance with the relevant requirements. These certifications are often necessary for products to enter the UK market and ensure consumer safety.

In comparison, the IEC does not have direct enforcement authority. Instead, it relies on national authorities of member countries to adopt and enforce its standards. These standards may be incorporated into national regulations or used voluntarily by manufacturers seeking global acceptance for their products. Certification and testing bodies accredited by the IEC provide conformity assessment services to ensure compliance with the standards.


In conclusion, while both BS EN and IEC are crucial players in the field of technical standards, they serve different purposes. BS EN focuses on British standards and operates under the jurisdiction of the UK, ensuring compliance with local laws. On the other hand, the IEC develops global standards that cover a wide range of electrical technologies, relying on voluntary adoption by member countries. Understanding the distinctions between these organizations is essential for companies operating in the international marketplace, allowing them to comply with relevant standards and ensure the safety and quality of their products and services.
