Energy Efficiency Programs Worldwide

Rev: 08 – 01/2015

Worldwide Standards Overview

Why is important to know and understand local efficiency regulations?

Understand OEMs and end customers needs;

Be a technical reference about efficiency regulations and get

customer’s trustworthy by giving correct support;

Avoid non compliance efficiency level on the end of the sales process;

Find the optimal point between stock volume and motor flexibility;

Be aware and ready to react during shifting of efficiency levels having

the right motors in stock and avoiding stock of outdated motors.

Procedure for non approved motors:

Check if motor efficiency is meeting ABNT requirements

Ask for an import license from Inmetro prior start export process

Dispatch the motors after receive the authorization from Inmetro

Submit sample motors to the lab for testing (Cepel, IEE/USP, Labelo)

Laboratory will issue a test certificate stating motor performance

After evlauate the test certificate Inmetro releases motors license

Labeling Middle East

Efficiency Level

Most of Middle East countries

do not have a minimum

efficiency requirement.

Cyprus, Israel and Turkey are

the exceptions, adopting the

same requirement as Europe

(IEC IE2).

Saudi Arabia is studying also

adopting IEC IE2.

Although IEC is generally

adopted, for some specific

projects NEMA efficiency

levels may be required.

Nameplate shall record :

Efficiency level (IE2/IE3)

Efficiency values for 50, 75 and 100% load

CE mark

Requirements (only for Cyprus, Israel and Turkey)
