It is my privilege to recognize all the thousands of experienced people who, during the past 60 years, developed the technical documents, trained new generations of specialists, and provided the best solutions for environmentally-controlled facilities and processes. Future generations, worldwide, will benefit as the requirements for revised standards are defined to meet the challenges. In my long career in the fields of ultra-clean spaces, ultra-pure water, chemicals and gasses required in laboratory and process applications, I can appreciate the partnerships that have been successful for their missions. The Institute of Environmental Sciences and Technology (IEST) will continue to be the leader. Thank you IEST and all those that volunteered to keep the clean room standards updated with technology.
