UL 2353-2021 pdf free download.Single- and Multi-Layer Insulated Winding Wire. 7.3 Performance tests conducted on wire whose insulation was wrapped or extruded over a bare conductor are representative of wire of the same construction except with the insulation wrapped or extruded insulation over enameled magnet wire. 7.4 Performance tests conducted on wire whose insulation was wrapped or extruded over an enameled magnet wire are only representative of similarly constructed wire produced using chemically and thermally similar enameled magnet wire. 8 Electric Strength Test – Straight Sample 8.1 For all constructions, five straight lengths of any wire 305-mm (12-in) long are to be subjected to an electric strength test in accordance with the requirements for electric strength as specified in the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1, the Standard for Medical Electrical Equipment, Part 1: General Requirements for Safety, UL 60601-1, or the Standard for Adjustable Speed Electrical Power Drive Systems – Part 5-1 Safety Requirements – Electrical, Thermal and Energy, UL 61800-5-1. The test voltage is to be in accordance with the applicable test voltages for electric strength tests in the Test Voltages for Electric Strength Tests Based on Peak Working Voltages (Part 1 and Part 2) Tables of UL 60950-1, the Test Voltages Table of UL 60601-1, or the Standard for Adjustable Speed Electrical Power Drive Systems – Part 5-1 Safety Requirements – Electrical, Thermal and Energy, UL 61800-5-1, Table 5.2.3.2.2DV.1 for basic and supplementary insulation and Table 21, Column 3 for reinforced insulation unless otherwise indicated below. The voltage is to be applied between the conductor and foil wrapped in direct contact with the center 150 mm (6 in) of the sample. 8.2 Additionally, for any wire evaluated for compliance with 5.1.1, five samples of each layer are to be subjected to an electric strength test in accordance with the requirements for electric strength, as specified in the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1, or the Standard for Medical Electrical Equipment, Part 1: General Requirements for Safety, UL 60601-1. This additional test is also required for insulation used in products evaluated in accordance with the Standard for Adjustable Speed Electrical Power Drive Systems – Part 5-1 Safety Requirements – Electrical, Thermal and Energy, UL 61800-5-1. The test voltage is to be as specified in Table 5.2.3.2.2DV.1 for basic and supplementary insulation and...
