3 Terminologies and Definitions
For the purposes of this standard, the following terminologies and definitions apply.
3.1
Cable conduit (code: FCP)
Fiber-cement pipe used to protect electric wires or cables in the fields of electric power, communication and others.
3.2
Joint (code: FCJ)
Pipe connectors made of cable conduit materials of the same (or higher) type.
4 Classification, Shape, Specifications and Mark
4.1 Classification
4.1.1 Cable conduit and joint are classified into Categories A, B and C according to the levels of external pressure load and anti-folding load.
- Category A is suitable for concrete encapsulation of cable duct bank and direct burial in sidewalk;
- Categories B and C are suitable for direct burial in vehicle lane or overhead laying.
4.1.2 Cable conduits are classified into superior products, first-class products and acceptable products based on their appearance quality and dimensional deviation.
4.2 Shape and specification
4.2.1 Shape
The shapes of the cable conduit and joint are shown in Figure 1 and Figure 2 respectively.

Figure 2 Joint
4.2.2 Specification
The specification and dimension of the cable conduit and joint are shown in Table 1.
4.3 Mark
The product shall be marked in the order of name, load level, specification (nominal inner diameter (mm) × wall thickness (mm) - length (m)), product class and standard number.
Example: First-class cable conduit with a load class of Class B, a nominal internal diameter of 175 mm, a wall thickness of 14 mm and a length of 3 m is marked as follows:
