Why are there so many emissions standards?

This post is by Steve Hayes, EMC & Safety Managing Director, TRaC

Keeping up to date with standards in any industry is a challenge but the EMC industry doesn't help itself with so many standards all covering essentially the same thing.

There are at least six common emissions standards based on international CISPR standards covering household, industrial, information technology, lighting and broadcast receiver products. In addition to these basic standards there are industry specific standards which make reference to the basic ones, resulting in 30-40 possible standards that a manufacturer can choose from.

The question is - why make it so complicated?

Surely the environment in which all these products have to operate is the same (a kettle and a microwave oven are both are designed to be used in a kitchen), so why do they need different tests performed on them with different limits?

Has the time come to look at other industries and use the same thought processes?  

Why can't the EMC industry have just one basic standard with appropriate limits and methods and then have subordinate annexes which inform the user of the standard and how to configure a given product (operating conditions) to provide a consistent result?
