csa meaning engineering

ECAs utilize the material properties and expected stress history to determine a flaw acceptance criteria which will ensure that welds will not fail during the construction or service life of the welded structure.

Now, CSA is a private testing body. In some cases, these flaws could potentially affect the integrity of the weld,[1] resulting in failure by fatigue, creep, brittle fracture, or yielding. Suggested Resources (0.00 / 0 votes) Rate this definition: CSA. When a product is certified by UL using the Canadian standards (CSA Standards), the product will have a C-UL certification mark expressing its conformity to the CSA Standards.

Information and translations of CSA in the most comprehensive dictionary definitions resource on the web. The best way to avoid the use and installation of these hazardous products is to buy only from trusted vendors and to avoid online auction sites and flea markets. Long hours, constant learning and training, and the ability to explain complex technical plans to lay people at the corporate level are almost always a part of this well-paying job. [1] The assessment can be used before the structure is in use, or during in-service inspection, to determine whether a given weld is in need of repair. ECAs are based heavily upon fracture mechanics principles, and reflect an improvement over traditional methods of weld quality assurance, which can be arbitrary or overly conservative.[3]. Please look for them carefully. The company produces numerous bibliographic databases in different fields of the arts and humanities, natural and social sciences, and technology. ANSI is a non-profit organization established in 1918 that administers and coordinates the standardization system in the U.S.

[8], API Standard 1104: "Welding of Pipelines and Related Facilities" (2007). The CSA acronym once stood for the Canadian Standards Association but is not a private testing body. For example, an electrician may use galvanized drywall screws in an installation, but they are not listed. To show a product conforms to CSA Standards, the manufacturer must obtain C-UL certification or CSA certification, or the seller needs to directly apply for certification to the officials of individual provinces. API Standard 579: "Fitness-for-Service" (2016), "Engineering Critical Assessment (ECA) Frequently Asked Questions", "Comparison of US and Canadian Transmission Pipeline Consensus Standards", "Reducing Pipeline Construction Costs With Girth Weld ECA", "DNV-RP-F108: Fracture Control for Pipeline Installation Methods Introducing Cyclic Plastic Strain", "Information for the Procurement and Conduct of NDT", https://en.wikipedia.org/w/index.php?title=Engineering_Critical_Assessment&oldid=976034526, Creative Commons Attribution-ShareAlike License, The stress history of the weld, including all cyclic and static stresses expected throughout the life cycle of the welded structure, The strength of the base metal and weld material, The flaw orientation (e.g., measurement of flaw length, This page was last edited on 31 August 2020, at 20:29.
Not all electrical products are required to be UL listed. All Rights Reserved. Clip, share and download with the leading design engineering magazine today. What does CSA stand for? There are several such organizations. [8], Several standards specific to ECAs for oil and gas pipelines have been developed.

The most commonly used of these are API 1104 Appendix A,[4] API 579,[7] CSA Z662[5] Annex K, and BS 7910.

Soon it was doing in-factory inspections in manufacturing facilities, and this practice continues today. Get instant definitions for any word that hits you anywhere on the web! During welding, defects or flaws can develop. To comply with the flaw acceptance criteria developed during ECA, non-destructive examination must be utilized. Thus, coverage includes materials science, environmental sciences and pollution management, biological sciences, aquatic sciences and fisheries, biotechnology, engineering, computer science, sociology, linguistics, and other areas. The numerical value of CSA in Chaldean Numerology is: 7, The numerical value of CSA in Pythagorean Numerology is: 5. BS 7910: "Guide to methods for assessing the acceptability of flaws in metallic structures" (2019). The purpose and agenda appear substantially unchanged. The standards differ in methodology and in extreme cases, can result in significantly different flaw acceptance criteria. Motion controllers: design from scratch or buy ready-made? Because the electrical inspector cannot be expected to disassemble or test all types of connected appliances, this individual has the option to rely on the UL listing, and that is the general practice. There are actually two types of UL marking: Listing certification and Recognition certification. [2] Ultrasonic testing is typically used due to its high accuracy, ability to identify flaw size and orientation, and its ability to provide feedback instantly. These ECAs relied heavily on recent developments in the field of fracture mechanics. UL Listing generally implies a certification for a final product.
; What does CSA mean? An example is the back-up battery in a fire alarm control panel. Stamped Circlip, The Hidden Costs of Bearing Systems & Assemblies, Ensuring Safe & Reliable Connector Designs. [2] ECAs are used throughout the energy, manufacturing, and infrastructure industries. Many UL standards have been adopted into ANSI/UL Standards. In addition, the flaws created during mechanized welding are typically oriented differently than flaws developed from manual welding. [8] While these criteria have been reliable historically, improvements made in welding technology and materials science are not taken into account. You consent to our cookies if you continue to use this website. Engineering Critical Assessment (ECA) is a procedure by which the safety of a welded structure with defects or flaws can be determined. The installation includes any connected electrical equipment such as a hard-wired range or light fixture.

'Community Supported Agriculture' is one option -- get in to view more @ The Web's largest and most authoritative acronyms and abbreviations resource. [3] Therefore, codes to determine weld quality must be developed. A growing problem has been the availability of electrical equipment and supplies, notably wire, at cut-rate prices, having counterfeit marking and falsely claiming UL listing. As the name implies, this is a Canada-based group that offers certification for mechanical and electrical products, as well as any general product that carries a high amount of user risk. 27 Oct. 2020. If they pass, the products are listed and/or labeled. The post The meaning of UL and CSA marks appeared first on Test & Measurement Tips. We use cookies to personalize content and ads, to provide social media features and to analyze our traffic. [9] As a result, over time, workmanship criteria have become increasingly conservative. [11], ECA-based flaw acceptance criteria are commonly used in the oil and gas industry, particularly with regard to qualification of girth welds on cross-country oil and gas transmission pipelines. "CSA." UL maintains facilities in 46 countries and provides services in 104 countries. What does CSA mean? As in the U.S. with UL, provincial laws in Canada stipulate that electrical appliances connected to a public power source must conform to CSA Standards.

Additionally, it is up to the “authority having jurisdiction” (AHJ) — primarily the local electrical inspector — to evaluate the electrical installation. Without specifically mentioning Underwriters Laboratories (UL), the National Electrical Code (NEC) makes frequent reference to “a nationally recognized testing laboratory”(NRTL). Solutions engineers are technology experts who design, sell and implement hardware or software solutions for clients. [8] However, for typical operating conditions, the criteria are easy enough to follow that practical differences between the standards are small. World-wide it has about 12,000 employees. Possible CSA meaning as an acronym, abbreviation, shorthand or slang term vary from category to category. Definitions.net. UL Recognition pertains to a certification for a part or a component built into a product. This conservatism results in unnecessary repairs, which can increase construction costs and can yield undesirable residual stresses at the location of the repair weld. Without specifically mentioning Underwriters Laboratories (UL), the National Electrical Code (NEC) makes frequent reference to “a nationally recognized testing laboratory”(NRTL).
