`NFPA flexible gas piping product approval renewal deadline`

2007/2008 NFPA letter to CSST manufacturers giving a 2014 deadline to prove product safety as a condition of approval renewal.

So this is the little extortion that goes on between the company and the State Plumbing Board. There are national codes like NFPA 54 and 58. The NFPA 54 committee has basically said they are not responsible for that part of the code. There are other NFPA codes that apply, but the code committee, NFPA, had given approval. By 2007 or 2008 there were enough questions that they went back to the companies and said, well, we gave you a ten-year approval which expires in 2014. You have to prove to us by 2014 that your product is safe.
