It mustn't exceed the higher limit from the HEPA filter. Before to execute this exam, DOP was made use of. But these days, it is actually changed with the PAO getting into account the carcinogenicity from the DOP. PAO = Poly Alpha Olefin DOP = Dispersed Oil Particulate seven. Tension difference It is calculated by using the manometer attached on the partitions from the adjacent region. The force variance is usually retained in between 5 and twenty mmHg pressure.
four. Particle depend A particle counter is used to carry out the exam. Particle rely is taken before the operation together with in the course of the working condition. The particle count really should be inside the range According to the expectations of Grade A, B, C, and D areas.
