Paramagnetic (mt)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
Materials in which the magnetic permeability is slightly greater than one. these materials are classified as nonmagnetic with a permeability of one for purposes of eddy current inspection. a material that can be slightly magnetized, but not sufficient to permit magnetic particle inspection.

Paramagnetic, английский
Paramagnetic material, английский
- A material that has a relative permeability slightly greater than unity and is practically independent of the magnetizing force. compare diamagnetic material; ferromagnetic material.
- In electromagnetic testing, a material that has a relative permeability slightly greater than unity and is practically independent of the magnetizing force.4
Permeability, английский
- Perméabilité
- The ease with which a fluid flows through a porous material (wood) in response to pressure.
- A measure of the ease with which water penetrates a material.
- The relationship of flow per unit area to differential pressure across a filter medium.
- (of a membrane) the ability to allow some substances to pass through
- Проницаемость о ~ to heat теплопроницаемость ~ of soil проницаемость грунта air ~ воздухопроницаемость
- The state or quality of being penetrable by fluids or gases.
- The specific permeability, k (in m? ) is often referred to simply as
- The capacity of a solid substance (such as rock) to transmit a fluid. the degree of permeability depends on the number, size, and shape of the pores and/or fractures in the rock and their interconnections. it is measured by the time it takes a fluid of standard viscosity to move a given distance. the unit of permeability is the darcy.
- The capacity of a porous rock to transmit fluids.
- A measure of a material’s ability to align its magnetic domains in response to an applied magnetic field.
- A measure of the ease with which a fluid flows through the connecting pore spaces of rock or cement. the unit of measurement is the millidarcy.
Classified, английский
- Секретно
- A general term defining information which must be controlled in the interest of national security. see “confidential,” “secret,” and “top secret.”
Nonmagnetic, английский
Немагнитный
Inspection, английский
- Surveillance
- Инспекция; осмотр
- Инспекция. аудит, проводимый официальными инстанциями. нс: действие уполномоченных органов, заключающееся в официальной проверке документации, оборудования, иных материалов, имеющих, по мнению уполномоченных органов, отношение к клиническому исследованию и находящихся в исследовательском центре, в помещениях спонсора и/или контрактной исследовательской организации, а также иных организациях, имеющих, по мнению уполномоченных органов, отношение к исследованию.
- The mode of working up the dead-reckoning by computed nautical tables. also, a general examination or survey of all parts of a sea or land force by an officer of competent authority.
- Инспектирование; проверка; контроль
- The process of measuring, examining, testing, gaging or otherwise comparing the unit with the applicable requirements. (asqc) . the term "requirements" sometimes is used broadly to include standards of good workmanship. (asqc)
- The examination of a good or service to ensure that it complies with specifications.
- The process of examining textiles for defects at any stage of manufacturing and finishing.
- Обследование
- Process of examining for possible defects or for deviation from established standards.
- Part of the penetrant testing process involving visual examination of a part for test indications after completion of the penetrant processing steps.
Magnetized, английский
A body is said to be magnetized when it possesses or can be made to possess that peculiar property whereby under certain circumstances it will naturally attract or repel a similar body in accordance with magnetic laws, example: drill rods become magnetized in use and will strongly attract other iron or steel articles.
Sufficient, английский
Достаточный

High radiation area, английский
Means an area, accessible to individuals, in which radiation levels could result in an individual receiving a dose equivalent in excess of 0.1 rem (1 msv) in 1 hour at 30 centimeters from the radiation source or from any surface that the radiation penetrates.
Magnetic materials, английский
Materials are affected by magnets in two general ways. some of them are attracted by a magnetic force, while others exert a repellent force. the first is called “paramagnetic” and the latter “diamagnetic.” in magnetic particle inspection we are not ordinarily concerned with either of the two classes, but with what may be termed a subdivision of the first class called “ferromagnetic materials.”
