ASME has replacement for IEEE – ANSI (standards) Code Issues – Eng-Tips
Close this window and log in. Note that IEEE  ieeee separate class designation letters for separable assemblies class designation ‘A’ and inseparable assemblies class designation ‘U’.
oeee Separable assembly or sub-assembly e. From Wikipedia, the free encyclopedia. Circulator or directional coupler. It breaks down a system into units, and then any number of sub-assemblies. The reference designator usually consists of one or two letters followed by a number, e. By joining you are opting in to receive e-mail. Are you an Engineering professional? Programmable logic controller PU: The unit is the highest level of demarcation in a system and is always a numeral.
This page was last edited on 25 Octoberat Did any document take its place as regards section 8 requiring marking of ref designations on equipment? IEEE or iees Reference Designations for Electrical and Electronics Parts and Equipments” is a standard that was used to define referencing naming systems for collections of electronic equipment. Zero sequence current transformer, also called a window-type current transformer. IEEE was ratified in Socket connector for another item not P or Ifee, paired with the letter symbol for that item XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.
Wire link “jumper” JFET: Subsequent demarcation are called assemblies and always have the Class Letter “A” as a prefix following by a sequential number starting with 1. Printed circuit board PLC: The IEEE renewed the standard in the s, but withdrew it from active support shortly thereafter. Thin-film transistor display TH: It’s easy to join and it’s free. Cathode ray tube CR: Metal-oxide-semiconductor field-effect transistor MOV: The Eng-Tips staff will check this out and take appropriate action.
Silicon unilateral switch SW: Especially valuable is the method of referencing and annotating cables plus their connectors within and outside assemblies.
Liquid crystal display LDR: Download Now Defense manufacturing is all about project manufacturing and project accounting. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. This standard, along with IEEEprovide the electrical designer with guidance on how iee properly reference and annotate everything from a single circuit board to a collection of complete enclosures.
A reference designator unambiguously identifies a component in an electrical schematic or on a printed circuit board. Retrieved from ” https: Any number of sub-assemblies may be defined until finally reaching the component.
