IEEE 841 SQUIRREL CAGE INDUCTION MOTOR
(OP)
IEEE 841 is Standard for Chemical and Petriochemical Industry.My customer wants to see 3/4 HP motor designed to meet IEEE 841 Standard. One comment sent to me is that 3/4 HP motors are not provided for that standard. Who can tell me is it true or not ? / I do not have here standard /

Almost a direct quote from the scope in IEEE841-2001.

Impro seals DE & NDE both.... in that Tatung motor ?

Without the seals, application in severe duty environments is limited.
Have added info to database.

Another approach is to have a 3/4HP motor qualified by a Nationally Recognized Testing Laboratory (NRTL) for the chemical and petrochemical industry applications.
RE: IEEE 841 SQUIRREL CAGE INDUCTION MOTOR
While having the motor tested and qualified by an independent agency might seem like a good idea,
it is VERY expensive.... and......
Additional: after you have read IEEE std 841 ... you will understand that the qualities defined therein, cannot be inspected into a motor; they have to be designed and built into it.... ergo.... third party qualification would not work in this instance. The motor either meets IEEE 841 or it doesn't.... If it does, then there'd be no need for a third party agency to qualify it. If it doesn't.. then a third party agency will not be able to qualify it to IEEE 841 compliance.
It's not quite the same as having a product that lacks a U.L. label tested at ETL labs and certified therefrom.
Your suggestion works only if the customer is willing to accept that while it doesn't necessarily comply with all of IEEE 841.... the NRTL qualification would be acceptable.
Worth a try....but get out the checkbook.
