1.1 This test method covers the determination of the pore size characteristics of geotextiles using an optical method and image analysis. 1.2 This method has been developed for determination of the Image Opening Size (IOS) of knitted geotextiles by image analysis. Other properties may be obtained...
1.1 This test method covers the determination of the Image Opening Size (IOS) of a geotextile by image analysis. 1.2 This test method shows values in both SI units and inch-pound units. SI units is the technically correct name for the system of metric units known as the International System...
4.1 This standard provides a guide for the other DDA standards (see Practices E2597, E2698, and E2737). It is not intended for use with computed radiography apparatus. Figure 1 describes how this standard is interrelated with the aforementioned standards. FIG. 1 Flow Diagram Representing the...
This part of IEC 61189 is used to quantify the deleterious effects of flux residues on surface insulation resistance (SIR) in the presence of moisture. Interdigitated comb patterns comprising long parallel electrodes on an IPC B53 standardized test coupon are used for the evaluation. Coupons are...
1.1 This practice, provided its limitations are understood, describes a procedure for quantitative measurement of the number and biological characteristics of colonies derived from a stem cell or progenitor population using image analysis. 1.2 This practice is applied in an in vitro laboratory...
This part of IEC 60286 contains information about the introduction of an innovative bulk blister packing system for miniaturized components, for example chip type components of size 1005 (metric) and smaller. It includes a proposal for standardization of the interface between the packaging...
This International Standard specifies the performance requirements, together with the test methods and conditions, required to show compliance of LED lamps with integral means for stable operation, intended for domestic and similar general lighting purposes, having: • a rated power up to 60 W; • a...
This specification prescribes the recommended standard metric sizes of solid round electrical conductors. The standard diameters of metric sizes of wires are preferred numbers calculated in accordance with the conventional mathematical principles. The standard metric size of...

5.1 Digital integrated circuits are specified to operate with their inputs and outputs in either a logical 1 or a logical 0 state. The occurrence of signals having voltage levels not meeting the specifications of either of these levels (an upset condition) may cause the generation and propagation...
5.1 There are many kinds of linear integrated circuits. Any given linear integrated circuit may be used in a variety of ways and under various operating conditions within the limits of performance specified by the manufacturer. The procedures of this practice provide a standardized way to measure...
1.1 These test methods cover two procedures for measuring the resistivity and Hall coefficient of single-crystal semiconductor specimens. These test methods differ most substantially in their test specimen requirements. 1.1.1 Test Method A, van der Pauw (1) 2-This test method requires a singly...

1.1 This guide describes several measurement and technical issues involved in quantifying the spread area of fixed cells. Cell spreading and the distribution of cell spread areas of a population of cells are the result of a biological response that is dependent on intracellular signaling mechanisms...
This guide is to assist experimenters in measuring the transient radiation upset threshold of silicon digital integrated circuits exposed to pulses of ionizing radiation greater than 103 Gy (matl.)/s. Discussion-This document is intended to be a guide to determine upset threshold, and is not...
4.1 Solid-state electronic devices subjected to stresses from excessive current pulses sometimes fail because a portion of the metallization fuses or vaporizes (suffers burnout). Burnout susceptibility can vary significantly from component to component on a given wafer, regardless of design. This...
These test methods cover the procedures for testing copper-clad laminates produced from fiber-reinforced, thermosetting polymeric materials intended for fabrication of printed wiring boards. Metric units are the preferred units for these test methods. Inch-pound units, where shown, are...
1.1 These test methods cover the procedures for testing copper-clad laminates produced from fiber-reinforced, thermosetting polymeric materials intended for fabrication of printed wiring boards. 1.2 The procedures appear in the following sections: Procedure Section Referenced Documents 2...
