The development of specifications for plastic pipe, fittings, and appurtenances; practices for joining and installing plastic pipes; test methods; terminology, systems and services specific to plastic piping systems and the stimulation of related research.
The work of the Committee may include the consideration of composite piping systems, and components which are partially plastic.
The work of the Committee will be coordinated with ASTM Committee and other organizations having mutual interests.
Use 3rd discussion point from F412 definition code, thermoplastic material designation to establish definitions for TMDC currently listed in PPI TR-4 (PE 1404, PE 2708, PE3608, PE3708 and PE 4710) minimum properties. New standard will refer to Table 1 of D3350 for density and slow crack growth properties requirements. Address the improving performance of PE pressure pipe compounds by establishing the concept of a suffix system. For example, a PE-RT performance would be addressed by defining R as resistant and T as higher temperature. A T table would be created in the standard with the higher temperature HDB (180F) requirement. Thus, a PE 4710-RT, would become the new thermoplastic material designation code for a PE 4710 with an established 180F HDB. Similarly, a PE 2708 with RT performance would become a PE 2708-RT. The standard will also likely incorporate by text or reference to another document prior generation materials (PE 2406, PE 3408, PE 3710, and PE 4708).
The title and scope are in draft form and are under development within this ASTM Committee.
