The object of this International Standard is to describe a measurement method of dielectric properties in the planar direction of dielectric plate at microwave frequency. This method is called a cavity resonator method. It has been created in order to develop new materials and to design microwave active and passive devices for which standardization of measurement methods of material properties is more and more important. This method has the following characteristics: ? the relative permittivity ε ' and loss tangent tanδ values of a dielectric plate sample can be measured accurately and non-destructively; ? temperature dependence of complex permittivity can be measured; ? the measurement accuracy is within 0,3 % for ε ' and within 5×10 for tanδ ; ? fringing effect is corrected using correction charts calculated on the basis of rigorous analysis. This method is applicable for the measurements on the following condition: – frequency : 2 GHz < f < 40 GHz; – relative permittivity: 2 < ε ' < 100; – loss tangent : 10 < tanδ < 10.

This International Standard defines a method for pulse testing to evaluate the voltage current response of the component under test and to consider protection design parameters for electro-static discharge (ESD) human body model (HBM). This technique is known as transmission line pulse (TLP) testing. This document establishes a methodology for both testing and reporting information associated with transmission line pulse (TLP) testing. The scope and focus of this document pertains to TLP testing techniques of semiconductor components. This document should not become alternative method of HBM test standard such as IEC 60749-26. The purpose of the document is to establish guidelines of TLP methods that allow the extraction of HBM ESD parameters on semiconductor devices. This document provides the standard measurement and procedure for the correct extraction of HBM ESD parameters by using TLP.

This standard applies to interface systems used to interconnect both programmable and nonprogrammable electronic measuring apparatus with other apparatus and accessories necessary to assemble instrumentation systems. It applies to the interface of instrumentation systems@ or portions of them@ in which the a) Data exchanged among the interconnected apparatus is digital (as distinct from analog) b) Number of devices that may be interconnected by one contiguous bus does not exceed 15 c) Total transmission path lengths over the interconnecting cables does not exceed 20 m d) Data rate among devices does not exceed 8 000 000 B/s The basic functional specifications of this standard may be used in digital interface applications that require longer distances@ more devices@ increased noise immunity@ or combinations of these. Different electrical and mechanical specifications may be required (for example@ symmetrical circuit configurations@ high threshold logic@ special connectors@ or cable configurations) for these extended applications. This standard may also be applicable to other instrumentation system elements@ such as processors@ stimulus@ display@ or storage devices@ and terminal units found useful in instrumentation systems. It applies generally to laboratory and production test environments that are both electrically quiet and restricted as to physical dimensions (distances between the system components). This standard deals only with the interface characteristics of instrumentation systems to the exclusion of design specifications?? consideration of radio-interface regulations@ performance requirements@ and safety requirements of apparatus. NOTE??For the latter two items@ reference is made to IEC 61010-1: 2001@ and IEC 60359:2001.1Throughout this standard@ and insofar as further distinction is not necessary@ the term ??system?? denotes the bit-parallel byte-serial interface system that@ in general@ includes all circuits@ cables@ connections@ message repertoire@ and control protocol to effect unambiguous data transfer between devices; and the term ??device?? or ??apparatus?? denotes any programmable measurement device or other product connected to the interface system that communicates information via@ and conforms to@ the interface system definition. A primary focus of this standard is to set forth an interface system to interconnect self-contained apparatus to other apparatus by external means. This same standard may be applied to interconnecting the internal subsections within a self-contained equipment.1For information on references@ see Clause 2.

Absolute probe coil methods, when used in conjunction with reference standards of known value, provide a means for determining the electrical conductivity of nonmagnetic materials. Electrical conductivity of a sample can be used as a means of determining: (1) type of metal or alloy, (2) type of heat treatment (for aluminum this evaluation should be used in conjunction with a hardness examination), (3) aging of the alloy, (4) effects of corrosion, and (5) heat damage.1.1 This test method covers a procedure for determining the electrical conductivity of nonmagnetic metals using the electromagnetic (eddy-current) method. The procedure has been written primarily for use with commercially available direct reading electrical conductivity instruments. General purpose eddy-current instruments may also be used for electrical conductivity measurements but will not be addressed in this test method. 1.2 This test method is applicable to metals that have either a flat or slightly curved surface and includes metals with or without a thin nonconductive coating. 1.3 Eddy-current determinations of electrical conductivity may be used in the sorting of metals with respect to variables such as type of alloy, aging, cold deformation, heat treatment, effects associated with non-uniform heating or overheating, and effects of corrosion. The usefulness of the examinations of these properties is dependent on the amount of electrical conductivity change caused by a change in the specific variable. 1.4 Electrical conductivity, when evaluated with eddy-current instruments, is usually expressed as a percentage of the conductivity of the International Annealed Copper Standard (IACS). The conductivity of the Annealed Copper Standard is defined to be 0.58 × 108 S/m (100 % IACS) at 20°C. 1.5 The values stated in SI units are regarded as standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
