Abstract
1. Способ измерения газовыделения материалов в вакууме, включающий размещение образца материала в измерительном объеме вакуумной системы со средствами откачки, вакуумирование измерительного объема до заданного давления разрежения, измерение скорости роста давления в измерительном объеме и анализ остаточного газа в нем, отличающийся тем, что после достижения заданного давления разрежения перед измерением скорости роста давления измерительный объем герметично отделяют от средств откачки, а перед каждым последующим измерением его уменьшают пропорционально уменьшению скорости роста давления в предыдущем измерении. ! 2. Способ по п.1, отличающийся тем, что уменьшение измерительного объема производят до уровня, при котором для данного измерения отношение максимального значения измеряемого давления к заданному давлению разрежения составляет 2…10. 1. A method of measuring the gas evolution of materials in a vacuum, including placing a sample of the material in the measuring volume of the vacuum system with pumping means, evacuating the measuring volume to a given vacuum pressure, measuring the pressure growth rate in the measuring volume and analyzing the residual gas in it, characterized in that after reaching predetermined vacuum pressure before measuring the pressure growth rate, the measuring volume is hermetically separated from the pumping means, and before each subsequent measurement of his mind shayut pressure proportionally to the reduction in the growth rate of the previous measurement. ! 2. The method according to claim 1, characterized in that the decrease in the measuring volume is carried out to a level at which, for a given measurement, the ratio of the maximum value of the measured pressure to a given vacuum pressure is 2 ... 10.
