PVC-U pipes are commonly used in soil and waste discharge systems in building structures, which include internal and external drains, ventilation, and rainwater. These pipes are designed to guarantee the safe and effective disposal of wastewater. The pipes used for draining are made from materials that have high resistance to corrosion, chemical reaction, and are durable. This makes the plastic pipes suitable for long-term underground and above-ground applications.
To maintain the quality of the water pipes, the Bureau of Indian Standards has established guidelines under IS 13592: 2013. This standard outline guideline is about material composition, dimensional accuracy, mechanical strength, and performance characteristics of PVC-U pipe. The plastic pipes with BIS certification on them ensure product reliability and are easily accepted in the Indian market.
What is IS 13592: 2013?
This is the Indian Standard for PVC pipes used in waste discharge systems, which outlines the standard requirements for mechanical strength, dimensions, material composition, and pressure ratings. This standard is set by the BIS (Bureau of Indian Standards) to ensure that product quality and safety are met, and the drainage and rainwater pipes are
- Made from approved PVC-U compound materials.
- Designed for efficient soil, waste, ventilation, and rainwater flow systems.
- Verified for mechanical strength and impact resistance.
- Tested for socket fitment and wall thickness.
- Manufactured under controlled extrusion processes to ensure uniform quality .

PVC Drainage and Rainwater Pipes BIS Approval Process
The BIS Authorisation process ensures that the rainwater PVC pipes meet the required standards for proper and efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration : Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories to verify material quality, dimensional accuracy, mechanical strength, and overall performance suitability for soil, waste, ventilation, and rainwater discharge systems.
- Application Submission : The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: If all requirements are satisfied, BIS grants the certification license under Scheme-I.
