The revised standard introduces a more scientific methodology to the design process, moving away from traditional "rule of thumb" practices like arbitrary air change rates. Instead, it advocates for precision through equation-based design, which tailors cleanroom performance to specific contamination control needs. This shift represents a significant evolution, fostering designs that are not only more efficient but also aligned with the latest regulatory expectations.
While challenges persist - particularly in identifying the correct input parameters for these advanced calculations - the presentation highlights the progress already achieved. Real-world examples illustrate how these principles are being applied effectively, showcasing the benefits of this rigorous, science-driven approach to cleanroom design and operation.
