The main emphasis of this recommended practice is the engineering design of optical fiber communication facilities serving, or connected to, electric supply locations. This recommended practice includes methods for providing telecommunication facilities serving electric supply locations using optical fiber cables, and their related electronic systems, extending across the zone of influence (ZOI). Keywords: CFJ, copper-fiber junction, electric power stations, electric supply locations, fiber optic systems, ground potential rise, high-voltage environment.

Required procedures for performing design tests for high-voltage distribution class and power class fuses, as well as for fuse disconnecting switches and enclosed single-pole air switches, are specified. These design tests, as appropriate to a particular device, include the following test types: dielectric, interrupting, load-break, radio-influence, short-time current, temperature-rise, time-current, manual-operation, thermal-cycle, bolt-torque, and liquid-tightness. Keywords: distribution enclosed single-pole air switches, fuse accessories, fuse design tests, fuse disconnecting switches, fuse enclosure package, high-voltage fuses.

This publication by the United Nations Conference on Trade and Development provides Level 3 Accounting and Financial Reporting Guidelines for Small and Medium-sized Enterprises (SMEs). It addresses the challenges SMEs face in applying complex international accounting standards, particularly in developing countries. The guidelines are designed to simplify financial reporting for smaller enterprises that are often owner-managed and have limited resources. The document proposes a three-tiered structure tailored to different sizes and types of enterprises, emphasizing a bottom-up approach that focuses on cash-based transactions. The intended audience includes SME owners, management, lenders, and government agencies, aiming to improve financial transparency and facilitate economic planning.
