Magnetic materials – Part 8-6: Specifications for individual materials – Soft magnetic metallic materials

Published by: 2016-12-08 / 2016-12-08 / 40 pages

IEC 60404-8-6:2016 specifies the general requirements, magnetic properties, geometric characteristics and tolerances as well as inspection procedures for pure iron, silicon-iron, nickel-iron and cobalt-iron. The materials are in the form of bar, billet, sheet, strip or wire. The alloys covered correspond to those defined by classes A, C1, C2, E1 to E4 and F1 to F3 in IEC 60404-1. This edition includes the following significant technical changes with respect to the previous edition: Removal of Table 2b).

Rapid Rise Fire Tests of Protection Materials for Structural Steel

Published by: 2017-02-24 / 2017-02-24
Please note: All interim revisions for this edition available at time of your purchase will be included.

1 Scope
1.1 This standard describes a test method for measuring the resistance of protective materials to rapid-temperature-rise fires.

1.2 The test method covers a full-scale fire exposure, intended to evaluate the thermal resistance of protective material applied to structural members and the ability of the protective material to withstand the fire exposure.

1.3 The standard describes the minimum testing requirements for classification, the limits of applicability of test results and acceptable methodology to determine the classification achieved.

1.4 The test method includes a supplementary test method for beams, intended to evaluate the ability of protective materials to perform when subject to significant deflections, for use in conjunction with the full-scale exposure test and applicable for beams and other sections subject to bending. Information published in accordance with this test method may also include product design tables for beams and sections subject to bending derived from the supplementary test method and accompanying methodology.

1.5 Information published in accordance with this test method may also include supplementary product design tables for alternate limiting temperatures derived from a multi-temperature analysis. Such tables are provided to aide in conditions where a performance-based-design approach is implemented, but are not part of the classification.

IEEE PC37.248

IEEE Draft Guide for Common Format for Naming Intelligent Electronic Devices (COMDEV)

Published by: / 39 pages

Scope

This guide provides a common convention for naming physical and virtual Intelligent Electronic Devices (IEDs). It discusses the various environments where device names are needed and how a common naming convention would be beneficial.

Purpose

The purpose of this guide is to provide a convention for naming physical and virtual IEDs in order to provide consistency to the point that automated systems and persons unfamiliar with the particular electrical system could determine what entities the IEDs are monitoring or reporting.

Magnetic materials – Part 15: Methods for the determination of the relative magnetic permeability of feebly magnetic materials CONSOLIDATED EDITION

Published by: 2016-12-05 / 2016-12-05 / 92 pages
IEC 60404-15:2012+A1:2016 specifies a solenoid method, a magnetic moment method, a magnetic balance method and a permeability meter method for the determination of the relative magnetic permeability of feebly magnetic materials (including austenitic stainless steel). The magnetic balance and permeability meter methods are both comparison methods calibrated using reference materials to determine the value of the relative magnetic permeability of the test specimen.
This consolidated version consists of the third edition (2012) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.

Standard Specification for Fuel Oils

Published by: 2016-10-01 / 2016-10-01 / 12 pages

1.1 This specification (see Note 1) covers grades of fuel oil intended for use in various types of fuel-oil-burning equipment under various climatic and operating conditions. These grades are described as follows:

1.1.1 Grades No. 1 S5000, No. 1 S500, No. 1 S15, No. 2 S5000, No. 2 S500, and No. 2 S15 are middle distillate fuels for use in domestic and small industrial burners. Grades No. 1 S5000, No. 1 S500, and No. 1 S15 are particularly adapted to vaporizing type burners or where storage conditions require low pour point fuel.

1.1.2 Grades B6-B20 S5000, B6-B20 S500, and B6-B20 S15 are middle distillate fuel/biodiesel blends for use in domestic and small industrial burners.

1.1.3 Grades No. 4 (Light) and No. 4 are heavy distillate fuels or middle distillate/residual fuel blends used in commercial/industrial burners equipped for this viscosity range.

1.1.4 Grades No. 5 (Light), No. 5 (Heavy), and No. 6 are residual fuels of increasing viscosity and boiling range, used in industrial burners. Preheating is usually required for handling and proper atomization.

Note 1: For information on the significance of the terminology and test methods used in this specification, see Appendix X1.

Note 2: A more detailed description of the grades of fuel oils is given in X1.3.

1.2 This specification is for the use of purchasing agencies in formulating specifications to be included in contracts for purchases of fuel oils and for the guidance of consumers of fuel oils in the selection of the grades most suitable for their needs.

1.3 Nothing in this specification shall preclude observance of federal, state, or local regulations which can be more restrictive.

1.4 The values stated in SI units are to be regarded as standard.

1.4.1 Non-SI units are provided in Table 1 and in 7.1.2.1/7.1.2.2 because these are common units used in the industry.

Note 3: The generation and dissipation of static electricity can create problems in the handling of distillate burner fuel oils. For more information on the subject, see Guide D4865.
