This standard details definitions, method of measurements and minimum performance characteristics for IEEE 802.20 MBWA terminals and base stations (BSs)/access nodes (ANs). The test methods are specified in this document; however, methods other than those specified may suffice for the same purpose.

This insulation coordination standard applies to three-phase alternating current (ac) systems above 15 kV. This standard specifies the procedure for selection of withstand voltages [basic lightning impulse insulation level (BIL) and basic switching impulse insulation level (BSL)] for equipment phase-to-ground and phase to-phase insulation systems. It also identifies a list of standard insulation levels, based on the voltage stress to which the equipment is being exposed. Although the principles of this standard also apply to transmission line insulation systems, the insulation levels may be different from those identified as standard insulation levels. The guide to this standard, IEEE Std 1313.2-1999, is an application guide with practical examples, intended to provide guidance in the determination of the withstand voltages and to suggest calculation methods and procedures. NOTE--IEEE Std 1313.2-1999 will be revised as IEEE Std C62.82.2 with its next revision.

This standard applies to security screening systems that utilize x-ray or gamma radiation and are used to inspect people who are not inside vehicles, containers, or enclosures. Specifically, this standard applies to systems used to detect objects carried on or within the body of the individual being exposed. The following types of systems are included in the scope of this standard: ⎯ Systems designated as fixed, portal, re-locatable, transportable, mobile, or gantry. ⎯ Systems employing… read more detection of primary radiation (transmission systems), or scatter radiation (backscatter systems), or a combination of both. ⎯ Systems that are primarily imaging but that also may have complementary features such as material discrimination, or automatic active or passive threat alerts. This standard will not address how to test these complementary features. read less

Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard establishes a normative definition of communication between personal telehealth blood pressure monitor devices and compute engines (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/IEEE 11073 terminology, information models,… read more application profile standards, and transport standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of communication functionality for personal telehealth blood pressure monitors. read less

Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard defines a common framework for making an abstract model of personal health data available in transportindependent transfer syntax required to establish logical connections between systems and to provide presentation capabilities and services needed to perform communication tasks. The protocol is optimized to personal health usage requirements and leverages commonly used methods and tools wherever possible.
