10、l National Differences included in the UL adoptionof the corresponding IEC standard.In its IEC-based standards, UL uses the notations indicated below to identify national difference type, andthese types are additionally noted in this document. The standard may not use all types of thesedeviations.D1

11、 - These are deviations which are based on basic safety principles and requirements, elimination ofwhich would compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acceptable, but adopting

12、 the IEC requirements would require considerable retesting or redesign on themanufacturers part.DC - These are deviations based on the component standards and will not be deleted until a particularcomponent standard is harmonized with the IEC component standard.DE - These are deviations based on edi

13、torial comments or corrections.DR - These are deviations based on the national regulatory requirements.Each national difference contains a description of what the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be appl

14、ied to the base IECtext:Addition / Add - An addition entails adding a complete new numbered clause, subclause, table,figure, or annex. Addition is not meant to include adding select words to the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subc

15、lause,table, figure, or annex without any replacement text.Modification / Modify - A modification is an altering of the existing base IEC text such as theaddition, replacement or deletion of certain words or the replacement of an entire clause,subclause, table, figure, or annex of the base IEC text.

42、) thick GradeA-Dfirplywood. A control (SHTP)with measurement thermocouples attached is to be inserted through an open hole in thebox such that the back of the body of the device is flush with the outside of the box. Theopen hole in the box is to have dimensions only as large as necessary to accommod

43、atethe protector (snug fit). The open hole is to be located in the side of the box such that it iscentered horizontally and the top of the open hole is 25.4 mm (1 inch) below the top of thebox.14.102ADV.3 The box is to be completely filled (flush with the top of the box) withexpanding polyurethane f

Onesupply source is to be adjusted to rated voltage and connected through the integralthermal protector across the maximum rated lamp load. The othe

45、r supply source is to beconnected to the SHTP heater and adjusted to the maximum voltage that will not result inthe integral thermal protector cycling within 7-1/2 hours (this usually will result inoperating the heater at less than rated voltage). If the thermal protector will not trip within7-1/2 h

46、ours at rated voltage and under the test conditions specified, two 102 by 102 by 44.5mm square (4 by 4 by 1-3/4 in) trade size metal outlet boxes are to be secured to the woodtest box over the base of the SHTP as shown in Figure 14.102ADV.1. A length of 2.0 mm2(12 AWG), Type THHN wire is to be arran

With the supply voltage to the SHTP heater at rated voltage, the box heaterconductors are to be energized by a low voltage source of supply with the supply adjustedto the maximum current that will not result in the thermal protector cycling within 7-1

48、/2hours. The lamp load is to be located such that any heat produced by it will not affect theoperation of the thermal protector. Temperature measurements are to be made at variousparts of the product using methods described in Clause 14.14.102ADV.5 After the test the control shall be evaluated as in
