MIL-STD-810F
MIL-STD-810, U S Department of Defense Test Method Standard, Environmental Engineering Considerations and Laboratory Tests, is a United States Military Standard that emphasizes tailoring an equipment's environmental design and test limits to the conditions that it will experience throughout its service life, and establishing chamber test methods that replicate the effects of environments on the equipment rather than imitating the environments themselves. Although prepared specifically for U.S. military applications, the standard is often applied for commercial products as well. The standard's guidance and test methods are intended to: * define environmental stress sequences, durations, and levels of equipment life cycles; * be used to develop analysis and test criteria tailored to the equipment and its environmental life cycle; * evaluate equipment's performance when exposed to a life cycle of environmental stresses * identify deficiencies, shortcomings, and defects in equipment ...

Climatic Testing Of Masks
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature an ...

Industrial PC
An industrial PC is a computer intended for industrial purposes (production of goods and services), with a form factor between a nettop and a server rack. Industrial PCs have higher dependability and precision standards, and are generally more expensive than consumer electronics. They often use complex instruction sets, such as x86, where reduced instruction sets such as ARM would otherwise be used. History IBM released the 5531 Industrial Computer in 1984, arguably the first "industrial PC". The IBM 7531, an industrial version of the IBM AT PC was released May 21, 1985. Industrial Computer Source first offered the 6531 Industrial Computer in 1985. This was a proprietary 4U rackmount industrial computer based on a clone IBM PC motherboard. Applications Industrial PCs are primarily used for process control and/or data acquisition. In some cases, an industrial PC is simply used as a front-end to another control computer in a distributed processing environment. Software ...

EN 62262
The European Standard EN 62262 — the equivalent of international standard IEC 62262 (2002) — relates to IK (impact protection) ratings. This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts. It provides a means of specifying the capacity of an enclosure to protect its contents from external impacts. The IK Code was originally defined in European Standard BS EN 50102 (1995, amended 1998). Following its adoption as an international standard in 2002, the European standard was renumbered EN 62262. Before the advent of the IK code, a third numeral had been occasionally added to the closely related IP Code on ingress protection, to indicate the level of impact protection — e.g. IP66(9). Nonstandard use of this system was one of the factors leading to the development of this standard, which uses a separate two numeral code to distinguish it from the old differing systems. The s ...

Rugged Computer
A rugged computer or ruggedized computer is a computer specifically designed to operate reliably in harsh usage environments and conditions, such as strong vibrations, extreme temperatures and wet or dusty conditions. They are designed from inception for the type of rough use typified by these conditions, not just in the external housing but in the internal components and cooling arrangements as well.What you need to know before purchasing a rugged mobile computer , ''LXE'', 2004. Typical environments for rugged laptops, Tablet computer, tablet PCs and Personal digital assistant, PDAs are public safety, field sales, field service, manufacturing, retail, health care, healthcare, construction, transportation/distrib ...

IP Code
The IP code or ingress protection code indicates how well a device is protected against water and dust. It defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and waterproofing, water. It is published in the European Union by the European Committee for Electrotechnical Standardization (CENELEC) as EN 60529. The standard aims to provide users more detailed information than vague marketing terms such as ''waterproof''. For example, a cellular phone rated at IP67 is "dust resistant" and can be "immersed in 1 meters of freshwater for up to 30 minutes". Similarly, an electrical socket rated IP22 is protected against insertion of fingers and will not become unsafe during a specified test in which it is exposed to vertically or nearly vertically d ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while NATO ...

Federal Advisory Committee Act
The Federal Advisory Committee Act (FACA) (), is a United States federal law which governs the behavior of federal advisory committees. In particular, it has special emphasis on open meetings, chartering, public involvement, and reporting. The U.S. General Services Administration (GSA) oversees the process. Overview Advisory committees The Federal Advisory Committee Act defines ''advisory committee'' as "any committee, board, commission, council, conference, panel, task force, or other similar group" that dispenses "advice or recommendations" to the President of the United States, and excludes bodies that also exercise operational functions. They are provisional bodies and have the advantage of being able to circumvent bureaucracy and collect a range of opinions. Committees composed of full-time officers or employees of the federal government do not count as ''advisory committees'' under FACA. Furthermore, the following organizations are also not governed by FACA: the Advisory Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
