4、are included in this specification.1.2 The requirements of this specification are intended toprovide pipe and fittings suitable for underground use innonpressure applications for sanitary sewers, storm sewers, andperforated and unperforated pipes for subdrainage.NOTE 1Industrial waste disposal lines
5、 should be installed only withthe specific approval of the cognizant code authority, since chemicals notcommonly found in drains and sewers and temperatures in excess of140F (60C) may be encountered.1.3 Pipe and fittings produced to this specification shall beinstalled in accordance with Practice D2
6、321.NOTE 2For perforated pipe applications, the size of the embedmentzone and permeability of the embedment material are important to thesystems ability to provide the desired level of infiltration or exfiltration.The gradation of the embedment material must be compatible with theperforation slot si
