1 загрязнение (в электробезопасности)
загрязнение
Присутствие инородного вещества: твердого, жидкого или газообразного (ионизированные газы), - которое может вызвать уменьшение диэлектрической прочности или поверхностного сопротивления.
[ ГОСТ Р 52319-2005( МЭК 61010-1: 2001)]
загрязнение
Любое добавление инородных веществ, твердых, жидких или газообразных (ионизированных газов), которые могли бы уменьшить электрическую прочность изоляции или удельное сопротивление поверхности.
[ ГОСТ Р 50030. 1-2000 ( МЭК 60947-1-99)]EN
pollution
any condition of foreign matter, solid, liquid or gaseous (ionized gases), that may affect dielectric strength or surface resistivity
[IEC 60947-1, ed. 5.0 (2007-06)]
pollution
any addition of foreign matter, solid, liquid or gaseous that can produce a permanent reduction of dielectric strength or surface resistivity of the insulation
NOTE – Ionized gases of a temporary nature are not considered as to be a pollution.
[IEV number 442-01-28]
contamination
the first is defined as area and the second as particulate. The first is caused by surface contaminants that cannot be removed by cleaning or are stained after cleaning. Those may be foreign matter on the surface of, for example a localized area that is smudged, stained, discoloured, mottled, etc., or large areas exhibiting a hazy or cloudy appearance resulting from a film of foreign materials
[IEC 62276, ed. 1.0 (2005-05)]FR
pollution
tout apport de matériau étranger solide, liquide ou gazeux (gaz ionisés) qui peut entraîner une réduction de la rigidité diélectrique ou de la résistivité de la surface
[IEC 60947-1, ed. 5.0 (2007-06)]
pollution
tout apport de matériau étranger solide, liquide ou gazeux qui peut entraîner une réduction permanente de la rigidité diélectrique ou de la résistivité de surface de l'isolation
NOTE – Les gaz ionisés de nature fugace ne sont pas considérés comme une pollution.
