SIXTEEN-BIT COMPUTER INSTRUCTION SET ARCHITECTURE
applies to passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification EN 60939-1. The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the e

Passive filter units for electromagnetic interference suppression - Part 2: Sectional specification: Passive filter units for which safety tests are appropriate - Test methods and general requirements
1.1 These requirements cover electromagnetic interference (EMI) filters installed on, or connected to, 600 V or lower potential circuits, 50 - 60 Hz, and installed in accordance with the National Electrical Code. 1.2 These requirements cover filters used to attenuate unwanted radio-frequency signals (such as noise or interference) generated from electromagnetic sources. These filters consist of capacitors and inductors used alone or in combination with each other and may be provided with resistors. 1.3 These requirements cover facility filters, cord-connected filters, direct plug-in filters, and appliance filters. 1.4 These requirements do not cover transient-voltage surge suppressors (that is, devices for repeated limiting of voltage surges on power circuits such as silicone avalanche diodes, metal oxide varistors, gas tubes, spark-gaps, etc). Transient Voltage Surge Suppressors are investigated under the Standard for Transient Voltage Surge Suppressors, UL 449. These requirements also do not cover EMI filters for outdoor use. 1.5 These requirements do not cover direct plug-in products and cord-connected products provided with more than two receptacles. A direct plug-in product employing more than two receptacles and having an EMI filter is investigated under the requirements for current taps in the Standard for Attachment Plugs and Receptacles, UL 498. A cord-connected product employing more than two receptacles and having an EMI filter is investigated under the requirements for Relocatable Power Taps, UL 1363. The EMI filter part of these products would be investigated to determine compliance with the requirements in this standard in so far as they apply. This new edition of ANSI/UL 1283 includes the following: 1) Clarification of the Scope, 2) The minimum requirements for insulating materials used within EMI filters, 3) Spacings - Relaxation of the requirements to Spacings section, 4) Capacitors - Minimum requirements for use of capacitors within EMI filters, 5) A full testing program for appliance filters is now required, 6) Temperature - revision to consider the heat generated when placing AC rated voltage across capacitors, 7) Endurance - Single test method at a minimum oven conditioning temperature, 8) Capacitor Discharge - Revised to reduce time to discharge to safe levels, 9) Capacitance Measurement - New requirements to determine if capacitance values change subsequent to the endurance test, 10) Details - Minimum requirements for adhesives used to secure labels, and 11) Other miscellaneous editorial updates.
