28、201 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the First Edition of the Standard for Sensor Operated Backwater Prevention Systems. This Edition of the Standard has been formally approved by the UL/ULC Joint Committee on
29、 Prevention of Storm and Sanitary Backow. This Standard has been developed in compliance with the requirements of SCC and ANSI for accreditation of a Standards Development Organization. Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value i
30、n other units in parentheses, the second value may be approximate. The rst stated value is the requirement. Appendix A, identied as Informative, is for information purposes only. UL is accredited by the American National Standards Institute (ANSI) and the Standards Council of Canada (SCC) as a Stand
31、ards Development Organization (SDO). ULC Standards is accredited by the Standards Council of Canada (SCC) as a Standards Development Organization (SDO). This ANSI/CAN/UL/ULC 1201 Standard for Safety is under continuous maintenance, whereby each revision is ANSI/CAN approved upon publication. If no r
32、evisions occur, the initiation of the review of this Standard will commence within 5 years of the date of publication. The review and action to revise or reaffirm this Standard will not exceed 5 years from the date of publication, unless the Standard is identied as tting within a stabilized category
33、, whereby the review will commence within the appropriate time frame set out by ULC Standards and Underwriters Laboratories Inc. In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadia
34、n authorities may require additional markings and/or installation instructions to be in both official languages. This is a First Edition joint National Standard of Canada and American National Standard. Comments or proposals for revisions on any part of the Standard may be submitted to UL or ULC at
35、any time. Proposals should be submitted via a Proposal Request in ULs On-Line Collaborative Standards Development System (CSDS) at http:/. Attention is drawn to the possibility that some of the elements of this joint Canadian and American standard may be the subject of patent rights. ULC Standards s

47、lectrical, performance tests and markings. 1.2 The purpose of this Standard is to enhance health and safety by: a) Specifying acceptable criteria for sensor operated backwater prevention systems; b) Serving as a guide for producers, distributors, architects, engineers, contractors, installers, inspe
48、ctors and users; and c) Promoting understanding regarding materials and manufacturing of sensor operated backwater prevention systems. 2 Units of Measurement 2.1 Only metric SI units of measurement are used in this Standard. If a value for measurement is followed by a value in other units in parenth
49、eses, the second value may be approximate. The rst stated value is the requirement. 3 Reference Publications 3.1 See Annex A for a list of publications referenced in this standard. Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.
