How testing certifications allegedly were obtained fraudulently from UL, ASTM, and AWWA is detailed in the Complaint. (It's an amazing story of failed test runs, ditched samples, changed protocols, etc.) Since these generally are "honor system" protocols, the Complaint should be read before concluding anything further. Home inspectors are still dealing with the fallout of UL stickers that were on Federal Pacific Electric panels for analogous reasons. There is no "lack lack of reported failures" among the state and local governments that joined the "whistleblower" claims (note the Nevada prison pipe in the post, others are in the related articles at The New York Times (nyt.com) and Plastics News (plasticsnews.com), though the list a week after the Complaint was unsealed is unlikely to be complete so soon. The 72-page complaint is at http://admin.phillipsandcohen.lawoffice.com under "Qui Tam" (whistleblower actions, at left, along with a little info on the background of that kind of lawsuit).
