The work described in this report is an extension of that described in the report "Investigation of Procedures for Determination of Thermal Performance Characteristics of Plastic Piping Used in Housing" (reference [I]). This earlier report dealt with the problems associated with establishing the important materials performance characteristics for the functional plumbing system. The state-of-the-art report [2] and the interim report on performance criteria [3] revealed that certain important areas of performance have not been considered in the usual approach to specifications and codes for plastic plumbing piping materials. The results reported herein and in reference [l] are part of the work undertaken to fill the gaps found in the state-of-the-art survey and in the initial effort to develop performance criteria and test procedures.
