31、13A 5 Preface (UL) This UL Standard 60730-2-1 3A, Standard for Safety for Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Humidity Sensing Controls, is to be used in conjunction with the third edition of UL 60730-IA. The requirements for humidity sens
32、ing controls are contained in this part 2 Standard and UL 60730-IA. Requirements of this part 2 Standard, where stated, amend the requirements of UL 60730-IA. Where a particular subclause of UL 60730-IA is not mentioned in 60730-2-13A, the UL 60730-IA subclause applies. The text, figures and tables
33、of IEC Publication Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Humidity Sensing Controls, IEC 60730-2-13 copyright 1995, are used in this Standard with the consent of the IEC and the American National Standards Institute (ANSI). The IEC copyrighte
34、d material has been reproduced with permission from ANSI. ANSI should be contacted regarding the reproduction of any portion of the IEC material. The IEC Foreword and Introduction are not a part of the requirements of this Standard but are included for information purposes only. Copies of IEC Public
35、ation 60730-2-13 may be purchased from ANSI, 11 West 42nd Street, New York, New York, 10036, (212) 642-4900. 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
36、suitability for their particular purpose. 6 UL 60730-2-13A FEBRUARY 5,2002 Foreword (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
37、 of this Standard. These requirements are based upon sound engineering principles, 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
38、authorities, and others having specialized experience. They are subject to revision 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 manufactu
39、rers product. C. A product which complies with the text of this Standard will 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 feature
40、s, characteristics, components, materials, or systems new or different from those 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 maintai
41、n the level of safety as originally anticipated by the intent of this standard. 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 propos
42、ed and adopted in conformance with the methods employed for development, revision, 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 opini
43、ons and findings of UL represent its professional judgment given with due consideration 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 sh
44、all not incur any obligation or liability for damages, including consequential 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 pr
45、operty shall be employed in conducting such tests. FEBRUARY 5,2002 UL 60730-2-13A 7 NATIONAL DIFFERENCES GENERAL National Differences from the text of International Electrotechnical Commission (IEC) Publication 60730-2-1 3, Automatic Electrical Controls for Household and Similar Use; Part 2: Particu
46、lar Requirements for Humidity Sensing Controls, copyright 1995, 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 standard. The standar
47、d 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, elimination of which wou
48、ld 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 par
49、t. 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 60730-2-13A FEBRUARY 5,2002 INTERNATIONAL ELECTROTECHNICAL COMMISSION AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD AND SIMILAR USE - Part 2: Particular Requirements for Humidity Sensing Controls FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national el
