British Standards
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to: Formally, as stated in a 2002 memorandum of understanding between the BSI and the United Kingdom Government, British Standards are defined as: Products and services which BSI certifies as having met the requirements of specific standards within designated schemes are awarded the Kitemark. History BSI Group began in 1901 as the ''Engineering Standards Committee'', led by James Mansergh, to standardize the number and type of steel sections, in order to make British manufacturers more efficient and competitive. Over time the standards developed to cover many aspects of tangible engineering, and then engineering methodologies including quality systems, saf ...

BSI Group
The British Standards Institution (BSI) is the national standards body of the United Kingdom. BSI produces technical standards on a wide range of products and services and also supplies standards certification services for business and personnel. History BSI was founded as the Engineering Standards Committee in London in 1901.Robert C McWilliam. BSI: The first hundred years. 2001. Thanet Press. London It subsequently extended its standardization work and became the British Engineering Standards Association in 1918, adopting the name British Standards Institution in 1931 after receiving a Royal Charter in 1929. In 1998 a revision of the Charter enabled the organization to diversify and acquire other businesses, and the trading name was changed to BSI Group. The Group now operates in 195 countries. The core business remains standards and standards related services, although the majority of the Group's revenue comes from management systems assessment and certification work. I ...

BS 5950
BS 5950 is a withdrawn British Standard for the design, fabrication and erection of structural steelwork. It was written for use in the UK but can be used worldwide. It was superseded by BS EN 1993 and withdrawn on 30 March 2010. It does not apply to bridges, which are covered by BS 5400. BS 5950 replaced BS 449, which used a permissible stress approach, and uses limit state design Limit State Design (LSD), also known as Load And Resistance Factor Design (LRFD), refers to a design method used in structural engineering.

Site Investigation
Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is called a site investigation. Geotechnical investigations are also used to measure the thermal resistance of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved. Geotechnical investigations are very important before any structure can be built, ranging from a single house to a large ware ...

BS 5930
BS 5930:2015, "the code of practice for site investigations", is a UK code of practice which came into effect on 31 July 2015 British Standards Institution. The stated purpose of the document is to "...deal(s) with the investigation of sites for the purposes of assessing their suitability for the construction of civil engineering and building works and of acquiring knowledge of the characteristics of a site that affect the design and construction of such work...". The document gives guidance on legal, environmental and technical matters relating to site investigation and includes a section on the description and classification of soils and rocks. History It supersedes BS5930:1999+A2:2010, which itself supersedes BS 5930:1981 which in turn supersedes CP2001: 1957 "Site investigations". BS5930:1999 was amended in December 2007 to avoid conflict with the newly introduced Eurocode 7 "Geotechnical Design" and the code is to be retained as a normative reference. BS5930:2015 is a furth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 9000
The ISO 9000 family is a set of international standards for Quality (business), quality management systems. It was developed in March 1987 by International Organization for Standardization. The goal of these standards is to help organizations ensure that they meet customer and other Stakeholder (corporate), stakeholder needs within the statutory and regulatory requirements related to a product or service. The standards were designed to fit into an integrated management system. The ISO refers to the set of standards as a "family", bringing together the standard for quality management systems and a set of "supporting standards", and their presentation as a family facilitates their integrated application within an organisation. ISO 9000 deals with the fundamentals and vocabulary of QMS, including the seven quality management principles that underlie the family of standards. ISO 9001 deals with the requirements that organizations wishing to meet the standard must fulfill. A companion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trap (plumbing)
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains. In heating systems, the same feature is used to prevent thermo-siphoning which would allow heat to escape to locations where it is not wanted. Similarly, some pressure gauges are connected to systems using U bends to maintain a local gas while the system uses liquid. For decorative effect, they can be disguised as complete loops of pipe, creating more than one U for added efficacy. General description In domestic applications, traps are typically U, S, Q, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as an S-bend. It was invented by Alexander Cumming in 1775 but became known as the U-bend followi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BS 1852
The RKM code, also referred to as "letter and numeral code for electrical resistance, resistance and capacitance values and Electrical component tolerance, tolerances", "letter and digit code for resistance and capacitance values and tolerances", or informally as "R notation" is a notation to specify resistor and capacitor values defined in the international standard International Electrotechnical Commission, IEC 60062 (formerly IEC 62) since 1952. Other standards including Deutsches Institut für Normung, DIN 40825 (1973), British Standard, BS 1852 (1975), Indian Standard, IS 8186 (1976), and Euronorm, EN 60062 (1993) have also accepted it. The updated IEC 60062:2016, amended in 2019, comprises the most recent release of the standard. Overview Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of el ...

Domestic AC Power Plugs And Sockets
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit. Plugs and wall-mounted sockets for portable appliances became available in the 1880s, to replace connections to light sockets. A proliferation of types were subsequently developed for both convenience and protection from electrical injury. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world, and many obsolete socket types are still found in older buildings. Coordination of technical standards has all ...
