    WK45790

    1. Rationale

    At the April ASTM C552 Task Group meeting held in Toronto, ON, the task group voted against complete removal of the Type II Pipe and Tubing thermal conductivity table. This was balloted in the previous cycle and recieved a number of negatives, one of which was determined to be persuasive. The ASTM C552 task group decided that the Type II thermal conductivity table will be retained and revised a previously proposed, with modifiications to the table to address previous comments and negatives. The Task group agreed that the data presented in previous meetings supports the proposed revisions to the ASTM C552 Type II Pipe and Tubing maximum thermal conductivity values listed in Table 1. Please note only those changes to the table as marked below (underlined and crossed out) are part of this ballot item.
