Chlorinated Polyvinyl Chloride (CPVC) fittings are commonly used in plumbing systems. They aid in the distribution of potable hot and cold water due to their excellent thermal resistance. The pipe fittings have the capability of withstanding pressure and high-temperature conditions. They can, therefore, be used in hot and cold water supply systems both in commercial buildings and residences. CPVC fittings have become popular in the modern-day piping system due to their ease of installation.
To ensure the quality and performance of the fittings, guidelines have been laid down by the Bureau of Indian Standards under IS 17546: 2021. This standard mentions the requirements for material composition, dimensional accuracy, pressure handling capacity, and overall performance of CPVC fittings. The companies must meet the standards to manufacture and sell the fittings to the customers.
What is IS 17546: 2021
This is the Indian Standard for CPVC fittings used in potable hot and cold water distribution systems. It outlines a few requirements to ensure the pipe fittings meet the quality and performance standards. As per the BIS (Bureau of Indian Standards), fittings are:
- Tested for hydrostatic strength
- Evaluated for leak-proof performance
- Verified for resistance to high temperature
- Checked for material quality
- Assessed for long-term durability
Who is eligible for CPVC Plumbing Fittings BIS License
BIS authorisation under IS 17546: 2021 is required for businesses involved in manufacturing, importing, or supplying fittings for hot and cold water.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the plumbing fittings are covered under QCO.
- Foreign Manufacturers - Need certification to export the product to India.

Testing and Inspection Requirements
To ensure safe performance of Fittings for Water Distribution Systems, the Bureau of Indian Standards outlines the minimum requirements under IS 17546: 2021. This certification ensures that manufacturers meet the quality and durability parameters as per the standard.
The BIS testing parameters and quality checks for the pipe fittings are listed below:
How to Get BIS Certification for CPVC Pipe Fittings
The BIS Authorisation process ensures that the fittings for water distribution systems 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 for material quality and dimensional accuracy.
- 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 conduct on-site inspections for manufacturing units to verify the production process, safety measures, and quality control systems.
- Grant of BIS License: Once all requirements are successfully fulfilled, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: After approval, the manufacturer can affix the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
