It defines specifications, distinguishes technical vs functional specifications, and introduces two main formats: short-form spec sheets and long-form technical specifications. The material describes how to structure and sanity-check a specification sheet with fields such as client, plant, pressure gauge details, options, procurement, revision, and notes. Guidance emphasizes not specifying equipment by model number alone and handling exceptions in writing.",{"@graph":14,"@context":76},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/pdhonline-course-g152-equipment-specifications-requirements-developments-and-use/670535/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/pdhonline-course-g152-equipment-specifications-requirements-developments-and-use/670535.png","ImageObject",300,407,{"name":42,"@type":43},"Rhys","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-02","2026-11-01",true,{"@type":52,"interactionType":53,"userInteractionCount":22},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68,72],{"name":59,"@type":60,"acceptedAnswer":61},"Why are equipment specifications important in engineered projects?","Question",{"text":62,"@type":63},"Purchasing equipment by only looking up manufacturer and model number in a catalog can cause many errors.

If it is a chemical plant there are chemical tanks and reactors, cooling towers and heat exchangers, Boilers and auxiliaries, and of course instrumentation and controls for all of these major pieces of equipment. Many times a person responsible for procuring apiece of equipment simply looks up the manufacturer and model number of the item ina catalog and sends an RFQ (request for quotation) to the manufacturer for the item in question. This method of procuring a piece of equipment can lead to many errors. The written specification can eliminate most if not all errors.  \nSPECIFICATIONS: 1. A list of requirements that must be met when making a material, part, component or assembly; installing it in a system; or testing its attributes or functions. 2. A set of standard requirements applicable to any product or process within the jurisdiction of a given standards-making organization: an industry consensus standard   [Comprehensive Dictionary of Instrumentation and Control] . The specifications covered in this course are better described as “Technical Specifications”rather than “Functional Specifications” as covered by UNC “Writing Equipment Specifications.  \nTypes of specifications: There are really only two types of specs, the short form orthe long form. The short form, sometimes referred to as “Spec Sheets” are commonly used to describe instruments and equipment that can be fully described on one standard form sheet.  \nShort form: (for a complete usable set go to  \n[https://ctjohnson.com/ZipFiles/INSTRSPC.ZIP](https://ctjohnson.com/ZipFiles/INSTRSPC.ZIP for downloading a Lotus v2 zip fi)[ for downloading a Lotus v2 zip fi](https://ctjohnson.com/ZipFiles/INSTRSPC.ZIP for downloading a Lotus v2 zip fi)le.) The bold type is part of the form. Although they are in an old spreadsheet Microsoft Excel ® will easily import the forms, however , they may require some changes in type size.  \n\n| S P E C I F I C A T I O N |  |  |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| Client:  \u003Cbr>\u003Cbr>Plant:   Location:   Client No.:  \u003Cbr>|  |  | PRESSURE |  |  |  | Sheet:  1 of 1  Date:  \u003Cbr>Job No.:   Spec.
