Standardization (American English) or standardisation (British English) is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, efficiency, and quality. It can also facilitate a normalization of formerly custom processes.
In , including economics, the idea of standardization is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. Divergent national standards impose costs on consumers and can be a form of non-tariff trade barrier.
Henry Maudslay developed the first industrially practical screw-cutting lathe in 1800. This allowed for the standardization of screw thread sizes for the first time and paved the way for the practical application of interchangeability (an idea that was already taking hold) to nuts and Screw.
Before this, screw threads were usually made by chipping and filing (that is, with skilled freehand use of and files). Nuts were rare; metal screws, when made at all, were usually for use in wood. Metal bolts passing through wood framing to a metal fastening on the other side were usually fastened in non-threaded ways (such as clinching or upsetting against a washer). Maudslay standardized the screw threads used in his workshop and produced sets of taps and dies that would make nuts and bolts consistently to those standards, so that any bolt of the appropriate size would fit any nut of the same size. This was a major advance in workshop technology. Maudslay's work, as well as the contributions of other engineers, accomplished a modest amount of industry standardization; some companies' in-house standards spread a bit within their industries.
This new standard specified a 55° thread angle and a thread depth of 0.640327 p and a radius of 0.137329 p, where p is the pitch. The thread pitch increased with diameter in steps specified on a chart. An example of the use of the Whitworth thread is the Royal Navy's Crimean War gunboats. These were the first instance of "mass-production" techniques being applied to marine engineering.
With the adoption of BSW by British railway lines, many of which had previously used their own standard both for threads and for bolt head and nut profiles, and improving manufacturing techniques, it came to dominate British manufacturing.
American Unified Coarse was originally based on almost the same imperial fractions. The Unified thread angle is 60° and has flattened crests (Whitworth crests are rounded). Thread pitch is the same in both systems except that the thread pitch for the in. (inch) bolt is 12 threads per inch (tpi) in BSW versus 13 tpi in the UNC.
The first modern International Organization (Intergovernmental Organization), the International Telegraph Union (now the International Telecommunication Union), was created in 1865 to set international standards in order to connect national telegraph networks, as a merger of two predecessor organizations (Bern and Paris treaties) that had similar objectives, but in more limited territories. With the advent of radiocommunication soon after its creation, the work of the ITU quickly expanded from the standardization of telegraph communications to the development of standards for telecommunications in general.
By the end of the 19th century, differences in standards between companies were making trade increasingly difficult and strained. For instance, an iron and steel dealer recorded his displeasure in The Times: "Architects and engineers generally specify such unnecessarily diverse types of sectional material or given work that anything like economical and continuous manufacture becomes impossible. In this country no two professional men are agreed upon the size and weight of a girder to employ for given work."
After the First World War, similar national bodies were established in other countries. The italic=no was set up in Germany in 1917, followed by its counterparts, the American National Standard Institute and the French AFNOR, both in 1918.
There are three regional standards organizations in Europe, which are known as European Standardization Organizations (ESOs), or European standards bodies. CEN, CENELEC, and ETSI are recognized via the EU'
/ref> CEN develops standards for numerous kinds of products, materials, services and processes. Some sectors covered by CEN include transport equipment and services, chemicals, construction, consumer products, defence and security, energy, food and feed, health and safety, healthcare, digital sector, machinery or services. The European Committee for Electrotechnical Standardization (CENELEC) is the European Standardization organization developing standards in the electrotechnical area and corresponding to the International Electrotechnical Commission (IEC) in Europe.
R. E. B. Crompton became concerned by the large range of different standards and systems used by electrical engineering companies and scientists in the early 20th century. Many companies had entered the market in the 1890s and all chose their own settings for , frequency, Electric current and even the symbols used on circuit diagrams. Adjacent buildings would have totally incompatible electrical systems simply because they had been fitted out by different companies. Crompton could see the lack of efficiency in this system and began to consider proposals for an international standard for electric engineering.
In 1904, Crompton represented Britain at the International Electrical Congress, held in connection with Louisiana Purchase Exposition in Saint Louis as part of a delegation by the Institute of Electrical Engineers. He presented a paper on standardization, which was so well received that he was asked to look into the formation of a commission to oversee the process. By 1906 his work was complete and he drew up a permanent constitution for the International Electrotechnical Commission. (2026). 9780444527455, Newnes. ISBN 9780444527455 The body held its first meeting that year in London, with representatives from 14 countries. In honour of his contribution to electrical standardization, Lord Kelvin was elected as the body's first President.
The ISO (ISA) was founded in 1926 with a broader remit to enhance international cooperation for all technical standards and specifications. The body was suspended in 1942 during World War II.
After the war, ISA was approached by the recently formed United Nations Standards Coordinating Committee (UNSCC) with a proposal to form a new global standards body. In October 1946, ISA and UNSCC delegates from 25 countries met in London and agreed to join forces to create the new International Organization for Standardization (ISO); the new organization officially began operations in February 1947.
In general, each country or economy has a single recognized National Standards Body (NSB). Examples include ABNT, AENOR (now called UNE, Spanish Association for Standardization), AFNOR, ANSI, BSI Group, DGN, DIN, IRAM, JISC, KATS, SABS, SAC, SCC, SIS. An NSB is likely the sole member from that economy in ISO.
NSBs may be either public or private sector organizations, or combinations of the two. For example, the three NSBs of Canada, Mexico and the United States are respectively the Standards Council of Canada (SCC), the General Bureau of Standards (Dirección General de Normas, DGN), and the American National Standards Institute (ANSI). SCC is a Canadian Crown Corporation, DGN is a governmental agency within the Mexican Ministry of Economy, and ANSI and AENOR are a 501(c)(3) non-profit organization with members from both the private and public sectors. The determinants of whether an NSB for a particular economy is a public or private sector body may include the historical and traditional roles that the private sector fills in public affairs in that economy or the development stage of that economy.
The existence of a published standard does not necessarily imply that it is useful or correct. Just because an item is stamped with a standard number does not, by itself, indicate that the item is fit for any particular use. The people who use the item or service (engineers, trade unions, etc.) or specify it (building codes, government, industry, etc.) have the responsibility to consider the available standards, specify the correct one, enforce compliance, and use the item correctly: validation and verification.
To avoid the proliferation of industry standards, also referred to as private standards, regulators in the United States are instructed by their government offices to adopt "voluntary consensus standards" before relying upon "industry standards" or developing "government standards". Regulatory authorities can reference voluntary consensus standards to translate internationally accepted criteria into public policy.
There are many that govern the operation and interaction of devices and software on the Internet, which do not use the term "standard" in their names. The W3C, for example, publishes "Recommendations", and the IETF publishes "Requests for Comments" (RFCs). Nevertheless, these publications are often referred to as "standards", because they are the products of regular standardization processes.
Moreover, standardized scientific frameworks can enable evaluation of levels of environmental protection, such as of marine protected areas, and serve as, potentially evolving, guides for improving, planning and monitoring the protection-quality, -scopes and -extents.
Moreover, technical standards could decrease electronic waste and reduce resource-needs such as by thereby requiring (or enabling) products to be interoperability, compatible (with other products, infrastructures, environments, etc), durable, energy-efficient, modularity, upgradeability/repairability and recyclability and conform to versatile, optimal standards and protocols.
Such standardization is not limited to the domain of electronic devices like smartphones and phone chargers but could also be applied to e.g. the energy infrastructure. Policy making policies "fostering standard design and interfaces, and promoting the re-use of modules and components across plants to develop more sustainable energy infrastructure". Computers and the Internet are some of the tools that could be used to increase practicability and reduce suboptimal results, detrimental standards and bureaucracy, which is often associated with traditional processes and results of standardization. Taxes and subsidies, and funding of research and development could be used complementarily. Standardized measurement is used in monitoring, reporting and verification frameworks of environmental impacts, usually of companies, for example to prevent underreporting of greenhouse gas emissions by firms.
Estimating the environmental impacts of food products in a standardized way – as has been done with a dataset of >57,000 food products in supermarkets – could e.g. be used to inform consumers or in policy. For example, such may be useful for approaches using personal carbon allowances (or similar quota) or for targeted alteration of (ultimate overall) costs.
There are typically four different techniques for standardization
Types of standardization process:
.
Probably the greatest downside of standardization for consumers is lack of variety. There is no guarantee that the chosen standard will meet all consumers' needs or even that the standard is the best available option. Another downside is that if a standard is agreed upon before products are available in the market, then consumers are deprived of the penetration pricing that often results when rivals are competing to rapidly increase market share in an attempt to increase the likelihood that their product will become the standard. It is also possible that a consumer will choose a product based upon a standard that fails to become dominant.Cowan, Robin. "High Technology and the Economics of Standardization." Paper presented at the International Conference on Social and Institutional Factors Shaping Technological Development: Technology at the Outset, Berlin, Germany, May 27–28, 1991. p. 20. In this case, the consumer will have spent resources on a product that is ultimately less useful to him or her as the result of the standardization process.
Increased adoption of a new technology as a result of standardization is important because rival and incompatible approaches competing in the marketplace can slow or even kill the growth of the technology (a state known as market fragmentation). The shift to a modularized architecture as a result of standardization brings increased flexibility, rapid introduction of new products, and the ability to more closely meet individual customer's needs.
The negative effects of standardization on technology have to do with its tendency to restrict new technology and innovation. Standards shift competition from features to price because the features are defined by the standard. The degree to which this is true depends on the specificity of the standard. Standardization in an area also rules out alternative technologies as options while encouraging others.Cowan, Robin. "High Technology and the Economics of Standardization." Paper presented at the International Conference on Social and Institutional Factors Shaping Technological Development: Technology at the Outset, Berlin, Germany, May 27–28, 1991. p. 12
