This is a third draft ballot written to address the 13 negatives received (6 from voting members and 7 from non-voting members) out of a total of 92 ballots cast addressing the content of the 2nd draft ballot. From the 92 votes returned there were (31) Affirmative, (55) Abstentions and (6) Negatives resulting in an 83.78% affirmative vote. That ballot was issued October 26, 2011 and was originally circulated under the same work item number listed above. A task group meeting was conducted in Tampa, Florida as part of the E05.22.1 Tunnel Operators meeting at which time all negatives were reviewed and discussed with the goal of achieving consensus regarding adding a CAN/ULC S102.2 reference to the E-84 test method as is consistent with existing section 6.3.1. I wish to thank all of the negative voters who participated in the Task Group dialogue in Tampa for their helpful guidance. The consensus opinion obtained at the Task Group in Tampa favored placement of a reference to the CAN/ULC S102.2 test method for thermoplastic piping in the Appendix under section X5.1. The CAN/ULC S102.2 addition in Section X5, listed along with other Steiner tunnel-type tests for specific products, is not meant to replace ASTM E-84 for all piping products or materials. I am seeking the CAN/ULC S102.2 reference addition to provide guidance to those requiring a suitable, consensus developed test method for thermoplastic piping in a modified Steiner tunnel-type test that specifically addresses the unique characteristics of thermoplastic piping and has a successful history of acceptance by regulators. Currently, there is no test protocol for thermoplastic piping referenced in ASTM E-84.
