Comparison between EN Standard and Chinese National Standard

Introduction

EN Standard and Chinese National Standard (CNS) are both important standards for products and services related to various industries. Although they have similarities, they have significant differences in terms of their scope, implementation, and requirements. This article provides a comparison between EN Standard and CNS, focusing on these three aspects.

Scope

EN Standard covers all European countries, while CNS applies only to China. EN Standard is often used as a reference by other countries as well, while CNS is less recognized outside of China. As for the types of products and services covered, the scope of EN Standard is broader than that of CNS. EN Standard covers a wide range of industries such as construction, energy, transportation, and consumer goods, while CNS mainly focuses on industries related to national security, public safety, and health.

Implementation and Requirements

EN Standard and CNS have different implementation procedures. EN Standard is developed by the European Committee for Standardization (CEN), which is composed of experts from different countries. CNS, on the other hand, is developed by the Standardization Administration of China (SAC), which is a government agency responsible for standardization activities in China. EN Standard has a more transparent and participatory development process, while CNS is more centralized and regulated by the government.As for the requirements, EN Standard and CNS have different approaches. EN Standard focuses on performance and safety requirements, and thus, it tends to be more flexible in terms of technical specifications. CNS, on the other hand, incorporates more detailed technical specifications and testing methods, which may make it more rigid and less adaptable to new technologies or innovations. Furthermore, EN Standard has a voluntary adoption system, while CNS is mandatory for products and services sold or used in China.

Conclusion

EN Standard and CNS are two important standards for different industries and regions. While they have similarities in terms of their purpose and function, they differ significantly in terms of their scope, implementation, and requirements. Companies that operate in both Europe and China need to comply with both standards and should be aware of the differences between them. In general, EN Standard offers greater flexibility and international recognition, while CNS provides more detailed testing and technical specifications, as well as mandatory compliance for products sold or used in China.
