REQUEST A SPECIAL CASE
The policies and procedures in PPI TR-3 are intended to cover HDB/ HDS/ PDB/ SDB/ MRS/ CRS listings for most thermoplastic piping materials. PPI recognizes there may be unusual cases, new materials or structures, issues or circumstances that are not covered in PPI TR-3, and that may justify an exception to the standard policies. To allow manufacturers an opportunity to have their material(s) listed by the PPI HSB when this occurs, the Special Case process can be utilized. The manufacturer may present its "Case" to the PPI HSB at one of their two annual meetings, usually in February and August, using the approved "Checklist for HSB Submissions" form in PPI TR-3 Appendix X.1.
