21989-2 is a topic of great significance in the Miscellaneous field. It is an international standard for Electromagnetic Compatibility (EMC), which is vital for the protection of products, services and installations in our lives.2 1989-2 is a comprehensive set of regulations that define the requirements for the performance of devices in a variety of environments. It applies to all types of electrical and electronic equipment, with the aim of ensuring a certain level of electromagnetic compatibility in order to protect against the risk of radio interference or other hazardous impacts. The standard applies to all types of equipment, including medical, industrial, telecommunications and consumer electronics.21989-2 covers a wide range of electromagnetic fields and frequencies. It covers frequencies from 9 kHz to 6 GHz and includes the wide-range of power levels common to most electronic devices. The standard also requires compliance with a variety of international standards, such as signal integrity testing, thermal and electrical safety, as well as safety requirements for systems and products.In terms of its application field, 21989-2 covers a wide variety of areas. In the medical sector it covers the operation of medical equipment, medical data transmission and storage. It is used for safety assessments of electronic products, devices and installations in the telecommunications and automotive sectors. It can also be used to ensure compliance for consumer electronics, home appliances, toys and gaming consoles.The working principle of 21989-2 is based on a set of rules and regulations intended to reduce potential disruptions caused by electromagnetic interference (EMI) and ensure compatibility between different equipment and different devices. It involves a combination of engineering techniques, analysis and testing procedures to ensure that the system or device will operate without interruption, without creating interference and without creating a significant risk to users and the environment.The standard defines a wide range of tests which are vital for the proper operation of electronic systems. These tests include emission tests, immunity tests, power line disturbance tests, signal integrity tests, and more. It also specifies methods for measuring and analyzing the signals that can be created by electronic equipment when operated in its environment. These tests are used to identify and remove potential sources of interference that could cause harm or disruption.21989-2 is an essential part of the EMC industry, it ensures a standard level of protection for electronic systems and equipment against interference and ensures products are fit for purpose. It is a complex and technical standard which is rigorously enforced throughout the industry to ensure safety and compliance.
