BIS ISI Certification for CPVC Pipes for Potable Hot & Cold Water – IS 15778
CPVC (Chlorinated Polyvinyl Chloride) pipes are widely used in potable hot and cold water distribution systems due to their excellent thermal resistance, durability, and long service life. In India, BIS ISI certification is essential to ensure that CPVC pipes used for drinking water applications meet national quality and safety standards.
BIS ISI certification for CPVC Pipes for Potable Hot and Cold Water Distribution Supplies is governed by Indian Standard IS 15778:2007. This standard defines requirements related to material composition, dimensions, physical and mechanical properties, hydrostatic pressure performance, and marking.
BIS ISI Mark certification under IS 15778 allows manufacturers to legally market CPVC pipes for potable hot and cold water applications in India and enhances acceptance among consumers, builders, and infrastructure authorities.

Overview of ISI Mark Certification for CPVC Pipes (IS 15778)
IS 15778 specifies the requirements for CPVC pipes intended for conveying potable water at both hot and cold temperatures in residential, commercial, and industrial plumbing systems. These pipes are designed to withstand high operating temperatures and pressure conditions.
The standard covers material characteristics, physical and mechanical properties, hydrostatic testing, and marking requirements to ensure consistent performance and safety throughout the product lifecycle.
BIS grants ISI Mark certification for CPVC pipes only after successful factory inspection, sample testing in BIS-recognized laboratories, and verification of quality control systems. Certified products are permitted to bear the ISI Mark, indicating conformity with Indian Standards.
Process Required for BIS ISI Mark Certification for CPVC Pipes for Potable Hot & Cold Water (IS 15778)
To obtain the BIS ISI Mark for CPVC Pipes for Potable Hot and Cold Water Distribution Supplies under Indian Standard IS 15778:2007, manufacturers must comply with the BIS Product Certification Scheme (Scheme-I). This certification ensures that CPVC pipes meet prescribed quality, safety, and performance requirements for potable water applications.
Estimated Timeline: The BIS ISI certification process for CPVC pipes generally takes around 30–45 days for Indian manufacturers and up to 5–6 months for foreign manufacturers, depending on factory readiness, inspection scheduling, and laboratory testing.
Step-by-Step Certification Process
- Application Submission: File the BIS application through the Manak Online portal by providing details of CPVC pipes, applicable Indian Standard (IS 15778), factory address, manufacturing process, machinery, and product range.
- Testing & Quality Readiness: Ensure availability of testing facilities for dimensional checks, hydrostatic pressure tests at ambient and elevated temperatures, impact resistance, and material conformity as prescribed under IS 15778.
- Factory Inspection: BIS officials conduct an on-site inspection to verify raw material control, extrusion process, quality control systems, marking practices, and compliance with the approved Scheme of Inspection and Testing (SIT).
- Sample Drawing and Testing: CPVC pipe samples are drawn during inspection and tested in BIS-recognized laboratories as per IS 15778 requirements.
- Grant of BIS License: Upon satisfactory inspection and successful test results, BIS grants the Certification Marks License (CM/L), authorizing the manufacturer to use the ISI Mark on CPVC pipes.
