Since they are published internationally, they don't protect the local

It's one way of encouraging social responsibility and raising
technical awareness abroad, if you are an important market for
the products of secondary industry.
 
They try to do this with tertiary industries (financial and
service), but the weasels generally tap dance faster than
the regulators, have more money and less conscience.
 
Hence CE.

Americans are cynical about CE. When I was designing stuff in Europe we
did take it seriously - just as seriously as UL.

If you have a European (or any international) market, you have to
take the IEC regulations seriously - even UL's and CSA's later
standards were/are coordinated with them . . . .with national
exceptions.

Their origins are found in the old GDR VDE standards that spawned them
and the regular revisions to current IEC regs keep foreign designers
hopping.

The actual standards that CE implies are widespread, including
such features as organizational (quality and recording),
environmental (process and material) - not just safety and EMC.

These are all apparently self-declared - compliance lists and proof
 being available 'on request'.for inspection. Any product that
threatens markets seriously will be challenged - but a serious
amount of capital is transgerred just through the distribution
of consumer trash.

Asian standards similarly mimic the IEC coat hangers, but their
purpose can be almost decorative, until they are not.
