标准结构要求, UL 1993 Scope:

1.1 These requirements are intended to cover both self-ballasted lamps and self-ballasted lamp adapters rated 120 to 347 V AC nominal for connection to screw-base, pin-base, or recessed single contact (RSC or R7) lampholders. These devices are intended for use in accordance with the National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical Code, Part I, in non-hazardous locations, and the Instalaciones Elerctricas (utilizacion), NOM-001-SEDE.

1.2 These devices incorporate resistance, reactance, or electronic (solid-state) type ballasts or power supplies. These devices employ various lamp technologies including, but not limited to, incandescent, fluorescent, high-intensity discharge lamps, light-emitting diodes.

1.3 These requirements also include Supplemental Requirements for Light-Emitting Diodes (LED), Supplement SA, for:

a)     Self-contained LED lamps, rated 120 to 347 V AC nominal for connection to screw-, pin-base, and recessed single contact (RSC or R7) lampholders,

b)     Lamps for replacement of an ANSI standardized fluorescent lamp, and consisting of light-emitting-diode (LED) lamp technologies, with control circuitry, and a driver or power supply. The LED driver and control circuitry will be either integral with the lamp or remote from the lamp, and

c)     Component LED lamps, with or without control circuitry, an ANSI base other than bases mentioned in (a), for connection to LED driver having a low voltage output, such as replacement for tungsten-halogen, MR11 and MR16 shaped lamps.

1.4 This standard does not apply to medium-to-medium base (E26) fittings that incorporate controls such as photocells, motion detectors, radio controls, or dimmers covered by other standards.

1.5 These devices are not intended for use with emergency exit fixtures or emergency exit lights.


5.1.1 Enclosures shall have the strength and rigidity to resist the abuses to which they are subjected, without increasing the risk of fire, electric shock, or injury to persons due to a reduction of the required spacing for live parts or the loosening or displacement of live parts.

5.1.2 An enclosure shall be of metal or of a polymeric material that complies with Clause 5.3.

5.1.3 A metal enclosure shall comply with the minimum thickness specified in Table5.1.

5.2.1 An enclosure shall not have openings wider than 2 mm (0.078 in), unless they do not permit a 2 mm (0.078 in) diameter rod of any length to contact live parts. The uninsulated live parts of a lampholder into which a lamp connects are not required to comply.

5.2.2 The enclosure openings in a lamp adapter shall be evaluated with the lamp removed.

5.2.3 A hole in an enclosure through which wires emerge to connect with a lamp connector shall be:

a)     Close-fitting to the emerging lead wires,

b)     Free of burrs, sharp edges, and the like, that can abrade the insulation, and

c)     Provided with a strain-relief means that complies with the strain relief test for lamp connectors of Clause 8.11.


UL 1993


5.3.1 (CAN) In Canada, a polymeric material shall comply with the requirements in CAN/CSA-C22.2 No. 0.17 and with the requirements of Clauses 5.3.2 to 5.3.4 and Clause 5.3.6 when the material is used to:

a)     Enclose electrical parts,

b)     Provide direct or indirect support of live parts, or

c)     Both.

5.3.1 (MEX) In Mexico, the parts of insulating material that contain live parts and external parts of insulating material that provide protection against electrical shock shall be subjected to the glow-wire test in accordance with NMX-J-565/2-11-ANCE and to the following:

a)     The test specimen shall be an end product. If it is necessary to take a part from the lamp in order to perform the test, care shall be taken to assure that the test conditions are not significantly different from that which occurs in normal use conditions;

b)     The temperature in the tip of the glow-wire shall be 650 C.

5.3.1 (USA) In the United States, a polymeric material shall comply with the requirements for portable equipment specified in UL 746C and with the requirements of Clauses 5.3.2 to 5.3.6 when the material is used to:

a)     Enclose electrical parts,

b)     Provide direct or indirect support of live parts, or

c)     Both.

5.3.2 A polymeric material used to enclose electrical parts shall have a Relative Thermal Index (RTI), including electrical and mechanical, with impact properties of at least the temperature measured during the temperature test of Clause 8.5, unless the measured temperature is less than 65 C.

5.3.3 A polymeric material used as an enclosure shall have a flammability rating of 5-VA, 5-VB, or V-0 in accordance with UL 94 or CAN/CSA-C22.2 No. 0.17.

5.3.4 A polymeric material used as an enclosure of a device marked for wet location use shall comply with the ultraviolet light exposure test specified in UL 746C or CAN/CSA-C22.2 No. 0.17.

5.3.5 With respect to UL 746C, the following tests are not required to be conducted:

a)     The abnormal operation and severe conditions test,

b)     The input after mold-stress relief distortion test, and

c)     the volume resistivity test.

5.3.6 A device shall comply with the mold-stress relief distortion test of Clause 8.9.

5.3.7 A polymeric material used for direct support as electrical insulation shall be able to withstand the hot wire ignition (HWI), the comparative tracking index test (CTI), and the high current arc ignition (HAI) to a level of at least the values in accordance with Table 5.2.

Table 5.2

Ratings of polymeric materials

(See Clause 5.3.7)

Environmental rating Flammability classificationb CTIc HWId HAIe
Minimum volts PLCf Minimum seconds PLCf Minimum seconds PLCf
Dry location 5-VA, 5-VB, V-0 100 4
Damp location 5-VA, 5-VB, V-0 175 3
Wet location 5-VA, 5-VB, V-0 250 2
Any 5-VA, 5-VB 15 3 30 2
Any V-0, VTM-0 7 4 15 3
a Enclosures of phenolic, urea, or other thermoset materials are acceptable as legacy materials. Thermoplastic materials shall comply with this table. First, the flammability classification is determined, and then CTI, HWI, and HAI requirements are determined as a function of the flammability classification.
b Flammability classification determined by prior classification or by 12-mm end-product (needle) flame test described in UL 746C or CAN/CSA-C22.2 No. 0.17.
c Comparative tracking index – Determined by prior classification or by end-product test described in UL 746C or CAN/CSA-C22.2 No. 0.17.
d Hot wire ignition – Determined by prior classification or by end-product test described in UL 746C or CAN/CSA-C22.2 No. 0.17.
e High-current arc resistance to ignition – Determined by prior classification or by end-product test described in UL 746C or CAN/CSA-C22.2 No. 0.17.
f For materials with other than VTM flammability classifications, the performance level class (PLC) for material shall be evaluated using the specimen thickness employed in the end product. PLCs have been established in order to give a consistent numbering for improved performance (PLC=0 is best; PLC=5 is poorest) and avoid an excessive level of implied precision. Material performances for several tests and recorded as PLC values are based on the mean test results rather than recording the exact numerical results.
