Exposure to radio frequency (RF) energy has been identified as an environmental factor to be considered before a radio transmitter will be certified by various regulatory agencies. Federal Communications Commission (FCC) OET Bulletin 65 (Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, edition 97-01, August 1997) outlines various Electromagnetic Energy (EME) evaluation methods as they apply to mobile, portable and base station Land Mobile Radio Products and provides assistance in determining whether a proposed or existing transmitting facility, operation or device complies with established FCC RF Exposure requirements.

This Standard presents a recommended plan for the implementation of Uniform Features for use in the Wireless Radiotelephone Service. Its intent is to describe services and features so that the manner in which a subscriber may place calls using such features and services may remain reasonably consistent from system to system. It is not intended to require that specific service offerings be required of all service providers.

FCC OET Bulletin 65 (Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, edition 97-01, August 1997) provides general procedures regarding RF exposure, which apply to many diverse circumstances. FCC OET Bulletin 65 outlines the various Electromagnetic Energy (EME) evaluation methods as they apply to Land Mobile Radio Products. FCC OET Bulletin 65 differentiates among mobile, portable and base station products and specifies the necessary evaluation method to determine compliance with FCC requirements on RF exposure.

This SAE Standard covers the mechanical and physical property requirements for austempered ductile iron (ADI) castings used in automotive and allied industries. Specifically covered are: a. hardness; b. tensile strength; c. yield strength; d. elongation; e. modulus of elasticity; f. impact energy; and g. microstructure. In this document SI units are primary and in-lb units are derived. Appendix A provides general information and related resources on the microstructural, chemical and heat treatment requirements to meet the mechanical properties needed for ADI in particular service conditions and applications.

The purpose of this document is to provide an informative overview of key technical requirements and standards considerations supporting specification of the Inter-RF Subsystem Interface (ISSI). Integral to the Project 25 (P25) system architecture, technical specification of the ISSI as an open interface is required to realize extended coverage areas for subscribers of P25 services through the interconnection, on an interoperable and non-proprietary basis, of P25 Radio Frequency Subsystems (RFSSs). This document is, therefore, primarily intended to facilitate the development of technical standards defining the service and protocol aspects of the ISSI. In addition, the document may facilitate development of technical standards concerning definition of measurement methods, performance recommendations, conformance tests, and interoperability test methods involving the ISSI.
