14、ssibility of multiple concurrent access. If a multiple-user version electronic Standard was purchased, one copy of the Standard may be stored on a single LAN file-server, or on the permanent storage device of a multiple-user computer, or on an Intranet server. The number of concurrent users shall no

Only one copy of the Standard may be printed from each single-user version of an electronic Standard. Only one copy

16、of the Standard may be printed for each authorized user of a multiple-user version of an electronic Standard. Because of differences in the computer/software/printer setup used by UL and those of electronic Standards purchasers, the printed copy obtained by a purchaser may not look exactly like the

An employee of an organization purchasing a UL Standard can make a copy of the page or pages being viewed for their own fair and/or practical internal use. The requirements in this Standard are now in effect, except for those paragraphs, sections, tables,

18、 figures, and/or other elements of the Standard having future effective dates as indicated in the preface. The prior text for requirements that have been revised and that have a future effective date are located after the Standard, and are preceded by a “SUPERSEDED REQUIREMENTS notice. New product s

19、ubmittals made prior to a specified future effective date will be judged under all of the requirements in this Standard including those requirements with a specified future effective date, unless the applicant specifically requests that the product be judged under the current requirements. However,

20、if the applicant elects this option, it should be noted that compliance with all the requirements in this Standard will be required as a condition of continued Listing, Recognition, and Follow-Up Services after the effective date, and understanding of this should be signified in writing.

Note - Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. 6 UL 60730-2-16A FEBRUARY 5,2002 For

37、eword (U L) A. This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL) under its Follow-Up Service for this category within the limitations given below and in the Scope section of this Standard. These requirements are based upon sound engineering princip

38、les, research, records of tests and field experience, and an appreciation of the problems of manufacture, installation, and use derived from consultation with and information obtained from manufacturers, users, inspection authorities, and others having specialized experience. They are subject to rev

39、ision as further experience and investigation may show is necessary or desirable. B. The observance of the requirements of this Standard by a manufacturer is one of the conditions of the continued coverage of the manufacturers product. C. A product which complies with the text of this Standard will

40、not necessarily be judged to comply with the Standard if, when examined and tested, it is found to have other features which impair the level of safety contemplated by these requirements. D. A product that contains features, characteristics, components, materials, or systems new or different from th

41、ose covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard

42、. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revis

43、ion, and implementation of this standard. E. UL, in performing its functions in accordance with its objectives, does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of UL represent its professional judgment given with due cons

44、ideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. UL shall not be responsible to anyone for the use of or reliance upon this Standard by anyone. UL shall not incur any obligation or liability for damages, including consequential

45、 damages, arising out of or in connection with the use, interpretation of, or reliance upon this Standard. F. Many tests required by the Standards of UL are inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting such tests. FEBRUARY 5,2002 UL 60730-2-

46、16A 7 NATIONAL DIFFERENCES GENERAL National Differences from the text of International Electrotechnical Commission (IEC) Publication 60730-2-1 6, Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Automatic Electrical Water Level Controls of the Float Ty

47、pe for Household and Similar Applications, copyright 1995, as amended in 1997, are indicated by notations (differences) and are presented in bold text. There are five types of National Differences as noted below. The difference type is noted on the first line of the National Difference in the standa

48、rd. The standard may not include all types of these National Differences. DR - These are National Differences based on the National Electrical Code (NEC) and other U.S. Regulatory Requirements. DI - These are National Differences which are based on basic safety principles and requirements, eliminati

49、on of which would compromise safety for U.S. consumers and users of products. D2 - These are National Differences based on safety practices. These are differences for IEC requirements that may be acceptable, but adopting the IEC requirements would require considerable retesting or redesign on the manufacturers part. DC - These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE - These are National Differences based on editorial comments or corrections. a UL 60730
