Standards

The fieldbus application layer (FAL) is an application layer communication standard designed to support the conveyance of time-critical application requests and responses among devices in an automation environment. The term time-critical is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions with attendant risk to equipment plant and possibly human life.

This part of IEC 61300 identifies two basic measurement methods for characterizing the spectral transfer functions of DWDM filter components. The transfer functions can be used to produce measurements of attenuation (A), polarization dependent loss (PDL), isolation , center wavering and bandwidth (BW)

This international standard specifies the performance and the functional characteristics of the electrical supply systems required for the instrumentation and control (I&C) systems important to safety of a nuclear power plant. Guidance is also given on the possible use of these supplies for other I&C systems

This part of IEC 61241 is application to electrical apparatus by enclosures and surface temperature limitation for use in areas where combustion dust may be present in quantities which could lead to a fire or explosion hazard . It specifies requirements for design construction and testing of electrical apparatus. This standard supplements the general requirements IEC 61241-0.

This action of IEC 1241-2 specifies two last methods for determining the minimum ignition temperatures of dust. The methods are not suitable for use will having explosive properties.

This part IEC 61241 specifies general requirements for the design construction testing and marking of electrical apparatus by an recognized safeguard technique for use in areas where combustible dust may be present in quantities that could lead to a fire or explosion hazard.

This part of IEC 61300 describes a method to measure the angular rotational misalignment of the ferrule mating surface of angled end face connector and its design orientation angle with respect to its key.

This international standard a application to industrial high-frequency dialectic heating installations used for the purpose of thermal applications such as melting, drying, welding insect extermination, and gluing of partially conductive or non-conductive materials such as plastics wood rubber, textiles, glass ceramic paper bamboo or foodstuffs, in both normal and protective atmospheres, using for example inert gasses or vacuum.

In addition to the scope of IEC 61326-1, this part of IEC 61326 specifies more detailed test configuration operational conditions and performance criteria for equipment with test and measurement circuits (both internal and or external to the equipment) that are not EMC protected for operational and or functional reasons, as specified by the manufactures.

This part of IEC 61326 specifies requirements for immunity and emissions regarding electromagnetic compatibility (EMC) for electrical equipment , operating from a supply or battery of less than 1 000 V a.c. or 1 500 V d.c. or from the circuit being measured, intended for professional , industrial-process, industrial -manufacturing and educational use, including equipment and computing devices for. - measurement and test, - control - laboratory use , accessories intended for use with the above (such as sample handling equipment.) intended to be used in industrial and non-industrial locations.
