Unplasticized Non-Pressure Polyvinyl Chloride (PVC-U) pipes are widely used in underground drainage and sewerage systems. These pipes are used to transfer domestic and industrial sewage without any kind of leakage in underground drainage and sewerage networks. These pipes are made up of rigid PVC, which is durable and also free of corrosion. Moreover, such pipes have very good structural strength.
For the continuous functioning of drainage piping, the Bureau of Indian Standards has established guidelines under IS 15328: 2003. Such standards specify all important requirements, including the quality of raw materials used, ring stiffness, impact strength, and performance of non-pressure PVC pipes. Manufacturers who comply with this standard are eligible to obtain BIS certification. They can use the ISI mark on their products, ensuring trust and acceptance in the Indian market.
What is IS 15328: 2003?
This is the Indian Standard for Unplasticized Non-Pressure PVC Pipes used in underground drainage and sewerage systems, which outlines the standard requirements for dimensions, material composition, pressure ratings, and mechanical properties. This standard is set by the BIS (Bureau of Indian Standards) to ensure that product quality and safety are met, and the sewer pipes are
- Tested for wall thickness and pipe length.
- Ensured to provide long-term performance.
- Verified for mechanical strength, such as ring stiffness.
- Checked for joint integrity and resistance to external loads.
- Made from high-quality PVC-U compounds.
- Designed for non-pressure underground drainage .
