Scope

This Standard specifies the structure and classification, materials, requirements, test
methods, inspection rules, marking, packaging, transportation and storage of high-
density polyethylene silicore plastic ducts (hereinafter referred to as “silicore ducts”).
This Standard is applicable to silicore ducts and supporting duct fittings used for the
protection of optical cables and power cables, which are laid in environments, such as:
underground direct burial, pipelines and trenches, etc.
This Standard is not applicable to silicore ducts and supporting duct fittings used for
the protection of optical cables and power cables, which are directly exposed outdoor
to the sunlight and with an air blowing pressure greater than 1.2 MPa.
