1.3

This standard also covers other rotating machinery such as, but not limited to, electric brakes, tachometers, encoders, and slip rings.

 

1.4

This standard does not address types of protection other than explosion-proof or dust-ignition-proof.

 

1.5

For Canada Only – This standard does not include Canadian energy efficiency or product performance requirements. For such requirements, see Annex A, item 19. It is possible that item 19 is referenced in whole or in part in federal, provincial, territorial, or local laws or regulations relating to energy efficiency or product performance. The appropriate governmental authorities should be consulted to confirm whether item 19 has been referenced in laws or regulations.

 

Note: This standard also does not include U.S. energy efficiency requirements for electric motors used in hazardous (classified) locations.
 

Project need:

To provide clarification on the current edition of the standard.  This proposed new amendment is being developed at the request of CANENA THC 2. It will provide the industry with clarification on the current edition of the standard.
