23、 JULY 10, 2015 CAN/ULC-S1088 ANSI/UL 1088 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common UL and ULC Standard for Temporary Lighting Strings. It is the First edition of CAN/ULC-S1088 and the Seventh edition of ANS

24、I/UL 1088. This Joint Standard was prepared by Underwriters Laboratories Inc., ULC Standards, and the Technical Committee on Temporary Lighting Strings (TCTLS). The standard was formally approved by the UL/ULC Technical Committee on Temporary Lighting Strings (TCTLS). The efforts and support of the

25、Technical Committee are gratefully acknowledged. 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 parentheses, the second value may be approximate. The rst stated value is the requirement. In Canada, there are two offi

26、cial languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possibility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages. Annex A and Annex B, both identifed as normat

27、ive, form a mandatory part of this Standard. 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. Level of Harmonization

28、This Standard is published as an identical standard between UL and ULC Standards. An identical standard is a standard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The

29、interpretation by the SDO of an identical or equivalent standard shall be based on the literal text to determine compliance with the standard in accordance with the procedural rules of the SDO. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soo

30、n as possible to each of the SDOs to more accurately reect the intent.
