Description
1-10 мм рт. ст. и вновь замер ют парциальное давление пробного газа F в изделий. Величину негерметичности определ ют по формуле;1-10 mm Hg. Art. and the partial pressure of test gas F in the products is measured again. The amount of leakage is determined by the formula;
Q (P.-p,,Q (P.-p ,,
где С - процентное содержание пробного газа в атмосфере;where C is the percentage of sample gas in the atmosphere;
S - скорость откачки. Преолагаемый способ позвол е повысить нацежность результатов испытаний .S - pumping speed. The proposed method allows to increase the nationality of the test results.
