• NEED FOR EMC STANDARDS
• The EMC standards are required for trouble free co-
existence and to ensure satisfactory operation.
• They are also required to provide compatibility
between electrical, electronic, computer, control and
other systems.
• Standards are required as manufacturer-user
interaction and user’s knowledge on EMI are limited.
• They are also required for establishing harmonized
standards to reduce international trade barriers and to
improve product reliability and life of the product.

• EMC STANDARDS: These are of two types Military
Standards : Military EMC standards are made in order
to ensure system-to-system compatibility in the real
time military environment. Military standards are more
stringent than civilian standards. Most of the military
standards are broadly based on MIL-STD 461 and 462.
Civilian Standards: The civilian EMC standards are
applicable for equipments used for commercial,
industrial and domestic applications. The emission
standards are specified to protect the broadcast
services from interference..

• ADVANTAGES OF EMC STANDARDS
• The advantages are:
• Compatibility, reliability and maintainability are
increased.
• Design safety margin is provided.
• The equipment operates in EMI scenario
satisfactorily.
• Product life and profits are increased.

6. • Other Military Standards The most important of
the military standards in EMI/EMC area are the
MIL-STD-461 and MIL-STD-462. As stated
elsewhere, many key developments in the
EMI/EMC area during the past 50 years carne
about as a result of the thrust given by the
military for this subject area. This interest of the
military also resulted in the development of many
other military standards in which EMI/EMC is an
important element. These include
