CSDS 10th Anniversary

On October 29, 2004 UL Standards launched a groundbreaking collaboration platform for standards development: http://csds.ul.com. For a decade, CSDS has provided for open, balanced participation in the consensus process and notifications about meetings with stakeholders for UL, ULC, UL Environment and other partners. On this 10th anniversary, we thank those who have been participating and sharing feedback over the years.
