Scan test

Scan test A test used to determine the local efficiency of an air filter. 

It is the responsibility of the Central Safety Testing Lab staff to scan test results into the database and to serve as database administrators. 2. It is the responsibility of the Product Safety and Product Regulatory Programs to develop MSDSs and Workplace Precaution Statements. 3. It is the responsibility of the project/process leader to ensure the Survey Sheets have been completed, and that MSDSs or workplace precaution statements have been requested. ... 

Change into the test position (downstream) and scan the total surface of the filter and the edges. Hold the probe approximately 2.5 cm from the surface of the filter with a scanning speed of not more than 3 ft/minute (scan test). 

In a double-blind, placebo-controlled, randomized trial of the effects of levocetirizine 5 mg and diphenhydramine 50 mg on objective measurements (a word-learning test, the Sternberg Memory Scanning Test, a tracking test, and a divided attention test that measured both tracking and memory scanning simultaneously) in 48 healthy... 

If E is equal to or greater than Epi, pitting-type attack will be predominant during the rapid-scan test. 

If the plot of Curve 1 continues from Epit with a large increase in current density versus a small increase in voltage, the test specimen will suffer vigorous local attack during the rapid-scan test.

Based on this concept, a crude oil/surfactant/brine system should have phase behavior (e.g., optimum salinity, IFT minima) similar to that of the pure alkane/ surfactant/brine system whose ACN is the same as the crude EACN. However, the concept of EACN is not practically applicable for several reasons. First, all the hydrocarbon compositions of a crade oil are not readily identified. Thus, the EACN of a crude oil cannot be calculated directly using Eq. 7.79. Second, measurement of the EACN of a crude oil requires a series of surfactant solutions to be tested to obtain individual minimum ITT. Then these surfactant solutions are tested against increasing alkane carbon numbers to find minimum IFTs. The ACN at which a surfactant solution also gives the lowest IFT for the crude oil is the EACN of the oil. Finding it is not an easy task. Third, several parameters affect the value of the EACN. Variations in EACN with alcohol cosolvent type, total WOR of the sample, and crude oil composition have been observed (Tham and Lorenz, 1981). In practice, we always select surfactants by scan tests using the actual crude oil for a specific application.

Scan test Each cell is written, or read, sequentially. The addressing sequence can count up fi om the minimum address (minmax) or down from the maximum address (maxmin). Either the XOT y axis can be the fast axis (rowfast or columnfast, respectively). 

Scan testing. Some or all of the sequential elements are converted into a shift register for control and observation purposes. 

Possible nondestructive testing techniques for adhesively bonded structures and composite materials will be introduced along with a literature survey of successes and applications to date. Emphasis on ultrasonic inspection will also be highlighted, including such topics as ultrasonic wave generation, wave velocity, dispersion, reflection factor, wave refraction, attenuation, ultrasonic field analysis, resolution, thickness and defect location measurement, and C-scan testing.

The purpose of this paper is to present an overview of the currently existing body scanners, the available types of technology and the standard process of scanning test subjects. 

Set the timing attributes for scan testing of the design appropriately, to avoid simulation mismatches. Set test default bldlr delay to a value after the rising edge of the capture clock. This variable specifies the time when data is applied to the bi-directionals in the input mode.
