  • Compressed Air Quality and ISO 8573-1 Purity Classes
    As an example, an Air Quality value of ISO8573-1:2010 [1 2 4] has a Class 1 for Particles, Class 2 for Water, and Class 4 for Oil These Class values will show the maximum value in each category To define the categories in more detail, I will separate the three to discuss the origins and solutions

  • Air Quality Specifications - Trace Analytics, the AirCheck Lab
    The tables below show the compressed air specifications as outlined by the BCAS and ISO 8573:2010 Many manufacturers establishing SOPs for compressed air used in the manufacturing process refer to these specifications to help establish their own guidelines
