ABS - The American Bureau of Shipping

The "American Bureau of Shipping" is an Industry Organization which establishes rules for the classification and construction of Steel Vessels. These rules are published annually under the title "Rules For Classification And Construction Of Steel Vessels." They are applicable to motors furnished for use on vessels covered by the specification. When "ABS" requirements are noted on a request for quotation or customer order, certain construction, approval and inspection requirements will be applicable depending on motor size and intended service. Reliance may furnish specialized equipment in accordance with these rules.

ANSI - American National Standards Institute

ASA Standards are national standards established by the American National Standards Institute which represents manufacturers, distributors, consumers and others concerned. ASA Standards may be sponsored by any responsible body and may become national standards only if a consensus of those having substantial interest is reached. Standards may cover a wide variety of subjects such as dimensions, specifications of materials, methods of test, performance, definition of terms, etc. ASA Standards frequently are those previously adopted by and sponsored by NEMA, IEEE, etc. The chief motor standard of ASA is C-50 - Rotating Machinery which is substantially in agreement with current NEMA Standards.

CSA - Canadian Standards Association

CSA is the clearing house and coordinating body for standards activity on a national level. Products covered by CSA are either "Certified" or "Labeled" depending on the standards involved. Motors and/or Generators for Ordinary Locations are examined by CSA against numerous CSA Standards and Canadian Electrical Code and if found to be acceptable are permitted to bear the CSA monogram as means of identification. Equipment used in Hazardous Locations bears a CSA Label except equipment bearing a UL label and meeting CSA Standards will bear only the CSA monogram as a CSA recognition mark. Motors thus marked are covered by the CSA Reexamination Service instead of Label Service. We have motors covered for both types of recognition. We also have Certification Listings for numerous variable speed drive units, etc. Equipment not bearing the CSA Certification identification is subjected to on-the-spot inspection by the Canadian Hydro-Power. If equipment is moved to another Province in Canada it will require inspection again by the Hydro-Power. CSA identification equipment doesn't require on-the-spot inspections by Hydro-Power.

UL - Underwriters' Laboratories, Inc.

Underwriters' Laboratories, Inc. is charted as a non-prof it organization, to establish, maintain, and operate laboratories for the examination and testing of devices, systems, and materials. The UL presently publishes more than 250 Standards for Safety for materials, devices, constructions and methods. UL also undertakes numerous research projects in areas of safety.

The objectives of Underwriters' Laboratories, as stated in the Certificate of Incorporation, are: "By scientific investigation, study, experiments, and tests, to determine the relation of various materials, devices, products, equipment, constructions, methods, and systems to hazards appurtenant thereto or to the use thereof affecting life and property and to ascertain, define and publish standards, classifications and specifications for materials, devices, products, equipment, constructions, methods, and systems affecting such hazards, and other information tending to reduce or prevent bodily injury, loss of life and property damage from such hazards."

The Laboratories is supported solely by charges made to clients and subscribers for its services. These charges are generally on a time and material basis and are not affected by the nature of the report rendered, whether favorable or unfavorable.


The following is a brief description of the types of services offered by UL, highlighting the meaning and coverage afforded by each type of service and the products or projects to which these services are applicable.


Products which have been evaluated with respect to all reasonably foreseeable hazards to life and property, and where such hazards have been safeguarded to an acceptable degree.


Products which have been evaluated with respect to one or more of the following:
  1. specific hazards only
  2. performance under specified conditions
  3. regulatory codes
  4. other standards, including international standards

Restricted generally to industrial or commercial products.


Products which have been evaluated only for use as components of end-product equipment covered by UL's Listing, Classification of Certificate Service.


Products comprising field-installed system at a specific location, or to specific quantities of certain products where it is impractical to apply the Listing Mark or Classification Marking to the individual product.


Products or systems involved in situations where the availability and capability of UL inspectors can assist local authorities having jurisdiction, or can provide inspection service to an industry group on a contract basis.

Fact-Finding and Research

Projects conducted on contract basis for manufacturers, trade associations, governmental agencies, and others in the interest of public safety.

  1. Fact-Finding Investigations- develop product or system information and data for use by applicant in seeking recognition in or amendment of a nationally recognized installation code or standard.
  2. Research - develops basic information, properties, and characteristics of materials, products and systems as related to safety to life or property - generally in the area of standards development.
*Follow-Up Service

Follow-up service is an integral part of each of these type services. It comprises primarily inspections and counter checks conducted in factories of manufacturers procedures for assuring production compliance with UL's requirements. Such inspections and checks are unannounced and at a frequency appropriate for the product or system involved.

Products submitted to UL and passing requirements of established UL Standards for Safety are listed by the UL as meeting their standards. Numerous classifications and means of identification are used to identify the products as meeting UL requirements. Reliance has several types of listings and each requires a recognized identification. Some of the areas are noted as follows:

  1. Electric Motors and/or Generators for use in Hazardous Locations as established by the National Electric Code bear a UL manifest plate which lists our File Number along with Classes of Hazardous Locations in which the equipment may be operated.
  2. Insulation Systems are listed under Reexamination Follow-Up Service and our Nameplates bear the lower case "r" along with the insulation identification to identify UL listing.
  3. Conduit Boxes for use in Hazardous Locations soon will require an identification plate bearing class information and a control number issued by the UL.
  4. Thermoprotectors for motors is covered by still another file. Products listed bear an identification model number. There are still other classes of listings too numerous to mention.

Reliance small AC motors now meet Underwriters Laboratories component recognition for motor construction. These motors include 48, 56 and 140 frames and are now listed with Underwriters' Laboratories for the STANDARD FOR ELECTRIC MOTORS- UL 1004. The Reliance file number is E- 54825 and will appear on the nameplate of approved designs as specified by UL.

This Standard represents the judgment of UL as to the basic requirements for construction and performance of electric motors. The motors covered under this classification are incomplete in certain constructional features or restricted in performance capabilities and are intended for use as components of complete equipment submitted for investigation rather than for direct separate installation in the field. THE FINAL ACCEPTANCE OF THE COMPONENT IS DEPENDENT UPON ITS INSTALLATION AND USE IN COMPLETE EQUIPMENT SUBMITTED TO UNDERWRITERS' LABORATORIES.

In other words, if a manufacturer wishes to sell a UL listed product, the complete product must be submitted to UL for investigation and UL recognized components (motors) must be used. Air conditioning condensers, refuse compactors and commercial meat slicers are examples of equipment requiring UL recognized components such as motors.

It should be noted that this standard DOES NOT COVER thermal protectors and motors for hazardous locations which are defined under separate UL Standards.

If required, please contact Small AC Motor Products for further clarification of this new UL Standard.
