Standard weights and measures were developed by the Indus Valley
Civilisation . The centralised weight and measure system served the
commercial interest of Indus merchants as smaller weight measures were
used to measure luxury goods while larger weights were employed for
buying bulkier items, such as food grains etc. Weights existed in
multiples of a standard weight and in categories. Technical
standardisation enabled gauging devices to be effectively used in
angular measurement and measurement for construction. Uniform units
of length were used in the planning of towns such as
A total of 558 weights were excavated from Mohenjodaro, Harappa, and Chanhu-daro , not including defective weights. They did not find statistically significant differences between weights that were excavated from five different layers, each measuring about 1.5 m in depth. This was evidence that strong control existed for at least a 500-year period. The 13.7-g weight seems to be one of the units used in the Indus valley. The notation was based on the binary and decimal systems. 83% of the weights which were excavated from the above three cities were cubic, and 68% were made of chert . Hindu units of time—largely of mythological and ritual importance—displayed on a logarithmic scale .
18TH CENTURY ATTEMPTS
Henry Maudslay 's famous early screw-cutting lathes of circa 1797 and 1800.
The implementation of standards in industry and commerce became
highly important with the onset of the
Henry Maudslay developed the first industrially practical screw-cutting lathe in 1800. This allowed for the standardisation 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 bolts .
Before this, screw threads were usually made by chipping and filing (that is, with skilled freehand use of chisels 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. Graphic representation of formulae for the pitches of threads of screw bolts
Joseph Whitworth 's screw thread measurements were adopted as the first (unofficial) national standard by companies around the country in 1841. It came to be known as the British Standard Whitworth , and was widely adopted in other countries.
This new standard specified a 55° thread angle and a thread depth of
0.640327p and a radius of 0.137329p, 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
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 1⁄2 in bolt is 12 threads per inch (tpi) in BSW versus 13 tpi in the UNC.
NATIONAL STANDARDS BODY
By the end of the 19th century, differences in standards between companies, was 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."
The Engineering Standards Committee was established in
First World War , similar national bodies were established
in other countries. The
Deutsches Institut für Normung
By the mid to late 19th century, efforts were being made to
standardize electrical measurement. Lord Kelvin was an important
figure in this process, introducing accurate methods and apparatus for
measuring electricity. In 1857, he introduced a series of effective
instruments, including the quadrant electrometer, which cover the
entire field of electrostatic measurement. He invented the current
balance , also known as the Kelvin balance or
Another important figure was R. E. B. Crompton , who 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 voltage , frequency , 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 Louisiana Purchase
Exposition in Saint Louis as part of a delegation by the Institute of
Electrical Engineers . He presented a paper on standardisation, 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 first international
standards organization, the International Electrotechnical Commission
. The body held its first meeting that year in London, with
representatives from 14 countries. In honour of his contribution to
electrical standardisation, Lord Kelvin was elected as the body's
first President. Memorial plaque of founding ISA in
The International Federation of the National Standardizing
Associations (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
In general, each country or economy has a single recognized National
Standards Body (NSB). Examples include
ABNT , AENOR ,
AFNOR , ANSI ,
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
Standards can be:
* de facto standards which means they are followed by informal convention or dominant usage. * de jure standards which are part of legally binding contracts, laws or regulations. * Voluntary standards which are published and available for people to consider for use.
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 .
In the context of social criticism and social science ,
standardization often means the process of establishing standards of
various kinds and improving efficiency to handle people, their
interactions, cases, and so forth. Examples include formalization of
judicial procedure in court, and establishing uniform criteria for
diagnosing mental disease.
In the context of information exchange, standardization refers to the process of developing standards for specific business processes using specific formal languages . These standards are usually developed in voluntary consensus standards bodies such as the United Nations Center for Trade Facilitation and Electronic Business ( UN/CEFACT ), the World Wide Web Consortium W3C , the Telecommunications Industry Association (TIA), and the Organization for the Advancement of Structured Information Standards (OASIS ).
There are many specifications that govern the operation and
interaction of devices and software on the
In the context of customer service , standardization refers to the process of developing an international standard that enables organizations to focus on customer service, while at the same time providing recognition of success through a third party organization, such as the British Standards Institution . An international standard has been developed by The International Customer Service Institute .
SUPPLY AND MATERIALS MANAGEMENT
In the context of supply chain management and materials management , standardization covers the process of specification and use of any item the company must buy in or make, allowable substitutions, and build or buy decisions.
In the context of defense, standardization has been defined by NATO as The development and implementation of concepts, doctrines, procedures and designs to achieve and maintain the required levels of compatibility, interchangeability or commonality in the operational, procedural, material, technical and administrative fields to attain interoperability.

The process of standardization can itself be standardized. There are at least four levels of standardization: compatibility, interchangeability , commonality and reference . These standardization processes create compatibility, similarity, measurement and symbol standards.
There are typically four different techniques for standardization
Types of standardization process:
* Emergence as de facto standard : tradition , market domination, etc.
* Written by a Standards organization :
* in a closed consensus process: Restricted membership and often having formal procedures for due-process among voting members * in a full consensus process: usually open to all interested and qualified parties and with formal procedures for due-process considerations
* Written by a government or regulatory body * Written by a corporation, union, trade association, etc.
Standardization/ Standardisation has a variety of benefits and drawbacks for firms and consumers participating in the market, and on technology and innovation.
EFFECT ON FIRMS
The primary effect of standardization on firms is that the basis of competition is shifted from integrated systems to individual components within the system. Prior to standardization a company's product must span the entire system because individual components from different competitors are incompatible, but after standardization each company can focus on providing an individual component of the system. When the shift toward competition based on individual components takes place, firms selling tightly integrated systems must quickly shift to a modular approach, supplying other companies with subsystems or components.
EFFECT ON CONSUMERS
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. 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.
EFFECT ON TECHNOLOGY
Much like the effect on consumers, the effect of standardization on technology and innovation is mixed. Meanwhile, the various links between research and standardization have been identified, also as a platform of knowledge transfer and translated into policy measures (e.g. WIPANO).
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.
