Electromagnetism meanings

In the case of transmission of test or calibration results by telephone, telex, facsimile or other electronic or electromagnetic means, the requirements of this International Standard shall be met. The transmission must be done in a way that meets the requirements of the customer. 

By electromagnetic means, surface charges can be induced and accumulated on the boundary of a dielectric material [94], Liquid samples can be treated the same way. For a non-uniform external electric field, interfacial shear stress in liquids is generated, inducing flow motion which tends to eliminate this stress. In this way, new interfaces are formed and mixing can be achieved. 

The electromagnetic mean-field has been expressed by the coefficients and (2)... 

Pipeline corrosion can be monitored by pushing "smart pig instruments through the line to measure local and general metal loss (by electromagnetic means). Related instruments have been developed that can make ultrasonic measurements of wall thickness. These methods are used to detect the presence of both external corrosion and internal corrosion. In some instances, video camera techniques can be used to evaluate the condition of internal pipe surfaces. Caliper typ>e measurements can be made in those relatively short lines that permit use of a cable to pull the instrument...

Most of these screens have an intense, high-speed (25 to 120 vibrations/s) lovv -arnplitiide vibration supplied bv means of an electromagnet. 

The vibrational motions of the chemically bound constituents of matter have fre-quencies in the infrared regime. The oscillations induced by certain vibrational modes provide a means for matter to couple with an impinging beam of infrared electromagnetic radiation and to exchange energy with it when the frequencies are in resonance. In the infrared experiment, the intensity of a beam of infrared radiation is measured before (Iq) and after (7) it interacts with the sample as a function of light frequency, w[. A plot of I/Iq versus frequency is the infrared spectrum. The identities, surrounding environments, and concentrations of the chemical bonds that are present can be determined. 

Radiant temperature The temperature of a surface emitting heat to surrounding bodies by means of electromagnetic radiation. 

ISO 9001 is not specific on what is meant by working environment . ISO 9001 only applies to product and factors that affect the product therefore working environment means the environment in which work on product is carried out. If temperature, cleanliness, humidity, electromagnetic, and other environmental factors need to be controlled to ensure conforming product then their control provides a suitable working environment.
