Introduction

In the pneumatic system, power is compressed gas through the loop to pass and control when using compressed gas pneumatic components, equipment

Or systems, indicate its characteristics, the need for a standard reference atmosphere, so that the data obtained under different atmospheric conditions can be compared.
