The American National Standards Institute (ANSI) has approved revisions in EASA’s Recommended Practice for the Repair of Rotating Electrical Apparatus. Designated as ANSI/EASA AR100-2010, the document is an updated version of ANSI/EASA AR100-2006. The Recommended Practice first received ANSI status (AR100-1998) in February 2000.

ANSI requires that standards be re-approved at least every five years. EASA’s Technical Services Committee proposed 36 changes to the Recommended Practice (ANSI/EASA AR100-2006); the ANSI acceptance group accepted all 36 and added 21 more proposals upon re-balloting. The ANSI acceptance group approved all 57 proposals without any objections. The Technical Services Committee proposals mainly added best practices taken from the EASA/AEMT Rewind Study. The ANSI acceptance group proposals were predominantly editorial.

The ANSI approval process that EASA must follow requires that the document be accepted by a group that presently includes representatives of industry (end users), testing laboratories, government and other standards organizations.

ANSI recognizes only one standard on a topic; therefore, the EASA Recommended Practice is the standard for repair of rotating electrical apparatus.

Based on a joint study by EASA and the Association of Electrical and Mechanical Trades (AEMT) of the United Kingdom, this publication concludes that using best repair/rewind practices maintains motor efficiency. Besides an Executive Summary, the report provides complete test data, extensive background information about test procedures and methodology, information about best practice repair/rewind procedures, resources for further reading, and an entire chapter on repair/replace considerations.

This article provides guidelines that service centers can follow to retain the operating efficiency of the electric motors they rewind and rebuild. It includes a list of DOs & DON'Ts, safe values, and correct procedures that are based on studies of variables that can impact the efficiency of rewound electric motors--e.g., core burnout temperature, winding design, bearing type, air gap and winding resistance. (Note: The article was first published in May 1992; reviewed and revised as necessary in November 2007 by EASA's Technical Services Committee.)

EASA-Q:2000 Quality Manual was created to provide EASA members a practical, cost-effective means of developing a quality management system. The manual is a guideline for implementing the ISO 9000 series of quality system standards. EASA-Q is designed so that all electrical apparatus service organizations, both small and large, can use it with minimal assistance. Inexpensive to implement and operate, EASA-Q can assist in reducing operating costs by helping to assure consistency - which often eliminates rework.

The package consists of a printed manual and CD-ROM which can be used to customize your program.
