Edit tests on Chlorinated polyvinyl chloride
Hello, and thank you for editing Wikipedia! I wanted to let you know that I undid your recent change to Chlorinated polyvinyl chloride, since it seemed to either be a test or simple mistake. Don't worry, it's great that you were bold and edited a page. I hope you'll stick around and help us improve the encyclopedia by signing up for a free account. It's possible I made a mistake, so if you feel I should not have reverted your edit, please let me know. Thanks again! 28bot (talk) 08:03, 30 March 2013 (UTC)
