الأسئلة الشائعة حول IS 8360 PART 2
?What are the dimension and tolerance requirements for 90-degree MDPE tees?▼
IS 8360 Part 2 (1977) sets forth that fabricated 90-degree tees must adhere to specified dimensions and tolerances for overall laying length (Z) as detailed in Clause 2.2.2 and Table 1. These dimensions vary with pipe size, with tolerances increasing proportionally to the fitting size. Wall thickness must not be less than that of the pipe to which the tee is attached, and outside diameters must conform to IS 8360 Part 1 (1977) standards.
?How does the wall thickness of fabricated tees relate to that of the connected pipes?▼
According to Clause 2.2.3 in IS 8360 Part 2, the wall thickness of fabricated 90-degree tees shall be equal to or greater than the wall thickness of the pipes they are welded to. This requirement ensures structural integrity and compatibility during installation and operation, preventing weakness at the joint.
?What marking standards are required for fabricated 90-degree tee fittings?▼
Per Clause 3.1.1 of IS 8360 Part 2, each fabricated 90-degree tee fitting may carry the Standard Mark for identification. Markings typically include the manufacturer’s identification, size, pressure rating, and batch or heat number to ensure traceability and compliance with quality standards.
?Are fabricated MDPE tees suitable for all potable water supply systems?▼
Fabricated 90-degree MDPE tees conforming to IS 8360 Part 2 and marked accordingly can be used in potable water supply networks, provided they meet the required pressure class and material compatibility. While the standard specifies suitability for drinking water, actual use depends on matching system pressure and health safety requirements.
?What are the licensing requirements for using the Standard Mark on fabricated fittings?▼
The use of the Standard Mark on fabricated fittings such as 90-degree tees is regulated under the Bureau of Indian Standards Act, 1986. Manufacturers must obtain a license from the Bureau of Indian Standards (BIS) to legally apply the Standard Mark. Licensing details and conditions are available from BIS regional and branch offices.
