Object The object of this Code is to establish safety standards for the installation and maintenance of electrical equipment. In its preparation, consideration has been given to the prevention of fire and shock hazards, as well as proper maintenance and operation. Compliance with the requirements of this Code and proper maintenance will ensure an essentially safe installation.…

2 Scope 2.1 General 2.1.1 The scope of this Standard is limited to the teleco mmunications aspect of commercial building design and construction, encompassing telecommunications considerations both within and between buildings. Telecommunications aspects are generally the pathways into which telecommunications media are placed and the rooms and areas associated with the building used…

1. SCOPE 1.1 This standard applies to inorganic zinc coating for use on steel superstructures, decks and hulls of vessels, bridges, towers, offshore drilling rigs, tank linings and reconditioned equipment that may be exposed to aggressive environnments, marine atmospheres and to intermittent immersion¹ in fresh or salt water. 1.2 The coating is suitable for use in areas where…

This International Standard specifies the Path Replacement additional network feature (ANF-PR), which is applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. ANF-PR is a feature which applies to an established call, allowing that call's connection between Private Integrated Services Network Exchanges (…

This International Standard specifies experimental methods for the evaluation of quality variation of iron ores for each type of iron ore being traded and for each handling plant. Two distinct approaches are specified. The first is to analyse interleaved samples composed of a number of paired increments taken and combined alternately following stratified sampling or systematic sampling as…

This QOS Framework is a structured collection of concepts and their relationships which describes QOS (Quality of Service) and enables the partitioning of, and relationships between, the topics relevant to QOS in Information Technology (IT) to be expressed by a common means of description. In particular, this QOS Framework is directed at IT systems and their use in providing Open Distributed…

Specifies a method for calculating the minimum approach distance for live working, at voltages between 1 kV and 800 kV, required to protect workers from system overvoltages. This standard addresses system overvoltages, and the working air distances between parts and/or workers at different potentials. The calculation of distances for d.c. voltages is presently under consideration.

The Station Management (SMT) Abstract Test Suite (ATS) directly supports the FDDI Protocol Implementation Conformance Statement (PICS) Proforma and works in correlation with three other FDDI ATS standards. This ATS for FDDI SMT provides the test procedures and test cases required to test the station management protocol described in the SMT standards. SMT specified the local portion of the system…
