CORD SETS AND POWER SUPPY - UL 817

A. INSULATING MATERIALS PLEASE NOTE THAT THIS REQUIREMENT APPLIES TO ALL POLYMERIC MATERIALS USED IN MOLDED-ON OR ULTRASONICALLY WELDED FITTINGS OF A CORD SET OR POWER SUPPLY CORD.

If your company employs only assembled-on Listed (AXUT) or Recognized (AXUT2) fittings that already comply with the material requirements in UL 498 in the above products
Paragraph 9.11 This paragraph requires that plastic materials used in the fittings of a cord set or power supply cord shall be UL R/C with a minimum flammability rating of 94 HB.

Exception: A polymeric material that has been subjected to the 12mm or 3/4 in end product flame tests described in the Standard for Polymeric Materials-Use in Electrical Equipment Evaluations, UL 746C, need not have a flame rating.

EVALUATIONS FOR COMPLIANCE

1. Manufacturers of cord sets and power supply cords that employ Recognized Plastic Materials (QMFZ2) having 94 HB flammability rating are asked to identify the manufacturer and designation of the material. UL will then review the Recognition report to determine compliance. If the material is in compliance, UL will add the Recognized (94 HB) Plastic Material to their Follow- Up Services Procedure.
2. Manufacturers of cord sets and power supply cords wishing to continue to use non- Recognized Component Plastic Materials can have their polymeric material(s) investigated as an Unlisted Component. The investigation will consist of conducting a Horizontal Burning Test per the requirements in the Standard for attests for Flammability of Plastic. Paragraph 95.1, These paragraphs were revised to require that each outlet 95.2, 95.3 of cord connectors of an outdoor-use cord set, shall be capable of being mated with a solid-blade attachment plug of the mating configuration after four- hour conditioning period, at a temperature of minus 20.0 +/- 1 C (minus 4+/-1.8 F) instead of minus 10.0 +/-2 C. One cord connector and one mating attachment plug are to be taken from the conditioning a chamber, and immediately upon removal, the fittings are to be mated with an insertion force of 40 lbf (178 N) instead of 30 lbf. Applied for a maximum of one minute without resulting in a gap, between the faces of the mated fittings, exceeding 0.079 inch (2 mm) instead of 0.060 inch (1.52 mm).
The differences from the existing test is that the temperature is at minus 20.0 +/-1 C, the insertion force is 40 lbf, and the resulting gap between the face of the mated fittings is not to exceed 0.079 inches.

EVALUATION FOR COMPLIANCE

1. Each manufacturer of cord connectors for outdoor-use cord sets will be asked to provide nine samples of each type of cord connectors for testing. In order to better select representative samples for testing, each manufacturer is asked to identify the catalog number and contact type of each cord connector for outdoor use as well as the volume and section reference.

PORTABLE ELECTRIC LAMPS- UL 153

48.8 UL has revised the requirements for portable cabinet Section 141 lights to clarify their intended use for surface or recessed Section 163 mounting and installation in a free standing open or Section 163A enclosed cabinet such as a china hutch, bookcase, bar, console, bed headboard, etc. To aid in this clarification, the product category in UL 153 has been changed from Cabinet Lights to Portable Cabinet Lights and installation instruction requirements are to include specific prohibitions of use as specified in new Section 163 A.
Action required: Manufacturers of portable cabinet lights under the category QOVJ are required to revise the instructions furnished with the product and to change the product designation. A copy of the instructions for each model of a portable cabinet light will be required to be added to the Follow-Up Service Procedure.
