This Standard contains basic requirements for products covered by Underwriters Laboratories Inc. (UL)under its Follow-Up Service for this category w
28、ithin the limitations given below and in the Scope sectionof this Standard. These requirements are based upon sound engineering principles, research, records oftests and field experience, and an appreciation of the problems of manufacture, installation, and usederived from consultation with and info
29、rmation obtained from manufacturers, users, inspection authorities,and others having specialized experience. They are subject to revision as further experience andinvestigation may show is necessary or desirable.B. The observance of the requirements of this Standard by a manufacturer is one of the c
30、onditions of thecontinued coverage of the manufacturers product.C. A product which complies with the text of this Standard will not necessarily be judged to comply withthe Standard if, when examined and tested, it is found to have other features which impair the level ofsafety contemplated by these
31、requirements.D. A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shall be evaluated using appropriate additional comp
32、onent and end-productrequirements to maintain the level of safety as originally anticipated by the intent of this standard. Aproduct whose features, characteristics, components, materials, or systems conflict with specificrequirements or provisions of this standard does not comply with this standard
33、. Revision of requirementsshall be proposed and adopted in conformance with the methods employed for development, revision, andimplementation of this standard.E. UL, in performing its functions in accordance with its objectives, does not assume or undertake todischarge any responsibility of the manu
34、facturer or any other party. The opinions and findings of ULrepresent its professional judgment given with due consideration to the necessary limitations of practicaloperation and state of the art at the time the Standard is processed.

35、upon this Standard by anyone. UL shall not incur any obligation or liability fordamages, 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
36、 safeguards forpersonnel and property shall be employed in conducting such tests.APRIL 16, 2002FIXTURE WIRE - UL 666INTRODUCTION1 Scope1.1 This standard states basic construction, test, and marking requirements for fixture wires. Fixture wiresare single conductor and are of the following types:600 v
37、olt Types: PTF, PTFF, KF-2, KFF-2, PF, PFF, PGF, PGFF, SF-2, SFF-2, ZF, ZFF, ZHF, TF,TFF, TFN, TFFN, RFH-2, FFH-2, RFHH-2, and RFHH-3300 volt Types: KF-1, KFF-1, SF-1, SFF-1, XF, and XFFThese types are for use as specified in Article 402 and other applicable parts of the National ElectricalCode (NEC
38、), ANSI / NFPA 70-1999. These types are as described individually in index Tables 4.1 4.8of this standard.2 Units of Measurement2.1 In addition to being stated in inch/pound units, each numerical requirement in this standard is alsostated in units that make the requirement conveniently usable in the
39、 various metric systems (practical SIand customary). Equivalent although not necessarily exactly identical results are to be expected fromapplying a requirement in inch/pound or metric terms. Equipment calibrated in metric units is to be usedwhen a requirement is applied in metric terms.3 References
