What is intrinsic safety?
Intrinsic safety (IS) is a protection technique for safe operation of electronic equipment in explosive atmospheres and under irregular operating conditions. The concept was developed for safe operation of process control instrumentation in hazardous areas, particularly North Sea gas platforms. As a discipline, it is an application of inherent safety in instrumentation.
What is embedded design?
Embedded design is a computing system dedicated to one or just a few tasks. Designing one is a challenging process which requires hardware and software knowledge. Examples of embedded systems are air traffic control systems, digital watches, medical systems, MP3 players and traffic control systems.
What is ROHS?
The Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment 2002/95/EC (commonly referred to as the Restriction of Hazardous Substances Directive or RoHS) was adopted in February 2003 by the European Union. This directive restricts the use of hazardous materials in the manufacture of various types of electronic and electrical equipment. Examples of these materials are Lead, Mercury, Cadmium, Hexavalent chromium, Polybrominated biphenyls (PBB), and Polybrominated diphenyl ether (PBDE).
What is CE?
CE marking is a declaration by the manufacturer that the product meets all the appropriate provisions of the relevant legislation implementing certain European Directives. CE marking gives companies easier access into the European market to sell their products without adaptation or rechecking. The letters CE stand for “Conformité Européenne” which means “European Conformity”. They are a declaration by the manufacturer that his product meets the requirements of the applicable European Directive(s).
What is ATEX?
There are two ATEX directives (one for the manufacturer and one for the user of the equipment):
- the ATEX 95 equipment directive 94/9/EC, Equipment and protective systems intended for use in potentially explosive atmospheres;
- the ATEX 137 workplace directive 99/92/EC, Minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.
Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely. There are four ATEX classification to ensure that a specific piece of equipment or protective system is appropriate and can be safely used in a particular application: 1. Industrial or Mining Application; 2. Equipment Category; 3. Atmosphere; and 4. Temperature.
What is FM?
FM Approval is an ATEX notified body (No. 1725) within Europe and can undertake the assessment, testing and certification of your products and manufacturing facility against the ATEX directive.
What is UL?
Underwriters Laboratories Inc. (UL) is an independent product safety certification organization. UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety.
What is a UL353?
These requirements cover limit controls, furnace fan controls, and other interlocks which are essentially switches responding to changes in liquid level, pressure, or temperature. Although not limited to such specific applications, these safety controls include those intended primarily to safeguard heating appliances, heating systems, processing systems, and air-conditioning and ventilating systems. These controls are for use in ordinary locations. Requirements for the installation and use of limit controls are included in Standards of the National Fire Protection Association, such as those for Installation of: Prevention of Furnace Explosions in Fuel Oil and Natural Gas-Fired Watertube Boiler Furnaces With One Burner, NFPA 85C-1991.
What is UL913?
Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division I, Hazardous (Classified) Locations.
