ISO 14644
ISO 14644 Standards were first formed from the FED-STD-209E, US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single standard for cleanroom classification and testing was long felt. After American National Standards Institute, ANSI and Institute of Environmental Sciences and Technology, IEST petitioned to International Organization for Standardization, ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1. In 2000, ISO 14644-2 was published, which began the process of FED-STD-209E being canceled. On November 29, 2001, the document was canceled and superseded by ISO 14644-1 and ISO 14644-2. ;ISO 14644 is now composed of: *ISO 14644-1: Classification of air cleanliness *ISO/DIS 14644-1.2(2014): Classification of air cleanliness by particle concentration *ISO 14644-2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1 *ISO/DIS 14644-2.2(2014): Moni ...

FED-STD-209E
FED-STD-209 E ''Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones'' was a federal standard concerning classification of air cleanliness, intended for use in environments like cleanrooms. The standard based its classifications on the measurement of airborne particles. Cancellation The standard was canceled on November 29, 2001 by the United States General Services Administration (GSA). The document was superseded by standards written for the International Organization for Standardization The International Organization for Standardization (ISO ) is an international standard development organization composed of representatives from the national standards organizations of member countries.

Designers
A designer is a person who plans the form or structure of something before it is made, by preparing drawings or plans. In practice, anyone who creates tangible or intangible objects, products, processes, laws, games, graphics, services, or experiences can be referred to as a designer. Overview Historically, the main area of design was regarded as only architecture, which was understood as the major art. The design of clothing, furniture, and other common artifacts were left mostly to tradition or artisans specializing in hand making them. With the increasing complexity in industrial design of today's society, and due to the needs of mass production where more time is usually associated with more cost, the production methods became more complex and with them, the way designs and their production are created. The classical areas are now subdivided into smaller and more specialized domains of design (landscape design, urban design, interior design, industrial design, furniture d ...

Cleanroom
A cleanroom or clean room is an engineered space, which maintains a very low concentration of airborne particulates. It is well isolated, well-controlled from contamination, and actively cleansed. Such rooms are commonly needed for scientific research, and in industrial production for all nanoscale processes, such as semiconductor manufacturing. A cleanroom is designed to keep everything from dust, to airborne organisms, or vaporised particles, away from it, and so from whatever material is being handled inside it. The other way around, a cleanroom can also help keep materials escaping from it. This is often the primary aim in hazardous biology and nuclear work, in pharmaceutics and in virology. Cleanrooms typically come with a cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure. The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger, equ ...

Environmental Management
Environmental resource management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors affected by conflicts that rise between meeting needs and protecting resources. It is thus linked to environmental protection, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, and wildlife management, and others. Significance Environmental resource management is an issue of increasing concern, as reflected in its prevalence in several texts influencing global sociopolitical frameworks such as the Brundtlan ...

ISO 14000
ISO 14000 is a family of standards related to environmental management that exists to help organizations (a) minimize how their operations (processes, etc.) negatively affect the environment (i.e. cause adverse changes to air, water, or land); (b) comply with applicable laws, regulations, and other environmentally oriented requirements; and (c) continually improve in the above. ISO 14000 is similar to ISO 9000 quality management in that both pertain to the process of how a product is produced, rather than to the product itself. As with ISO 9001, certification is performed by third-party organizations rather than being awarded by ISO directly. The ISO 19011 and ISO 17021 audit standards apply when audits are being performed. The requirements of ISO 14001 are an integral part of the European Union's Eco-Management and Audit Scheme (EMAS). EMAS's structure and material are more demanding, mainly concerning performance improvement, legal compliance, and reporting duties. The curr ...

Annexes
Annexation (Latin ''ad'', to, and ''nexus'', joining), in international law, is the forcible acquisition of one state's territory by another state, usually following military occupation of the territory. It is generally held to be an illegal act.: "Annexation means the forcible acquisition of territory by one State at the expense of another State. It is one of the principal modes of acquiring territory... in contrast to acquisition a) of terra nullius by means of effective occupation accompanied by the intent to appropriate the territory; b) by cession as a result of a treaty concluded between the States concerned (Treaties), or an act of adjudication, both followed by the effective peaceful transfer of territory; c) by means of prescription defined as the legitimization of a doubtful title to territory by passage of time and presumed acquiescence of the former sovereign; d) by accretion constituting the physical process by which new land is formed close to, or becomes attached to ...

Chemical Substance
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

ISO 14698
The ISO 14698 Standards features two International Standards on contamination, biocontamination control for cleanrooms. IEST, the Secretariat and Administrator of ISO Technical Committee 209, helped develop this series of ISO 14698 Standards. *ISO 14698-1, Cleanrooms and associated controlled environments—Biocontamination control, Part 1: General principles and methods *ISO 14698-2, Cleanrooms and associated controlled environments—Biocontamination control, Part 2: Evaluation and interpretation of biocontamination data ISO 14698-1 ISO 14698-1 was first written in 2003. ISO 14698-1 describes the principles and basic methodology for a formal system to assess and control biocontamination, where cleanroom technology is applied, in order that biocontamination in zones at risk can be monitored in a reproducible way and appropriate control measures can be selected. In zones of low or negligible risk this standard may be used as a source of information. ISO 14698-2 ISO 14698-2 beca ...

Employment
Employment is a relationship between two parties regulating the provision of paid labour services. Usually based on a contract, one party, the employer, which might be a corporation, a not-for-profit organization, a co-operative, or any other entity, pays the other, the employee, in return for carrying out assigned work. Employees work in return for wages, which can be paid on the basis of an hourly rate, by piecework or an annual salary, depending on the type of work an employee does, the prevailing conditions of the sector and the bargaining power between the parties. Employees in some sectors may receive gratuities, bonus payments or stock options. In some types of employment, employees may receive benefits in addition to payment. Benefits may include health insurance, housing, disability insurance. Employment is typically governed by employment laws, organisation or legal contracts.
