- CHLORINATED POLYVINYL CHLORIDE PIPES are the most preferred and used in hot and cold water plumbing systems as they are able to resist high temperatures and pressures.
- Compared to regular PVC pipes, these pipes can withstand better and have a longer life span, especially in Indian climatic conditions.
- As the pipes are corrosion-resistant, they can be used in the water supply systems of the residential, commercial, and industrial sectors.
- Standardization with Indian standards assures safety, quality that is consistent, and acceptance by government and big infrastructure projects.
- It is very important that these pipes are made and controlled in terms of quality so that cracking, deformation, and failure of long-term performance can be avoided.
Introduction | CHLORINATED POLYVINYL CHLORIDE PIPE
In India’s plumbing and water distribution sector, BIS Certification for CHLORINATED POLYVINYL CHLORIDE PIPES (IS 15778:2007) is considered a mandatory requirement rather than a mere formality of the procedure. CPVC pipes are the most common choice for the transport of hot and cold water in residential buildings, hospitals, hotels, and huge projects of the infrastructure, where safety and durability over the period are of utmost importance. To avoid situations where the failure is the result of the use of substandard materials, the Bureau of Indian Standards has introduced area IS 15778:2007, which not only defines the quality, strength, and thermal resistance standards but also sets them clearly. This specification is confirmed through the certification that CPVC pipes made or traded in India are required to consistently meet the set standards in terms of such features as pressure resistance, temperature stability, and material composition. For manufacturers and importers, acquiring BIS certification is more than just fulfilling regulations – it is a key to gaining acceptance in the market, being eligible for government tenders, and increasing brand trust. In the absence of a valid BIS licence and ISI marking, production, distribution, or sale of CPVC pipes will be illegal in the Indian market.
What is CHLORINATED POLYVINYL CHLORIDE PIPE (IS 15778: 2007)
CHLORINATED POLYVINYL CHLORIDE PIPES (IS 15778:2007) is an Indian standard that defines the quality, performance, and testing requirements of CPVC pipes made for water supply systems both hot and cold. It certifies that CPVC pipes must be able to securely resist high temperatures, internal pressure, and long-term usage that are typical of Indian residential, commercial, and institutional plumbing applications.
Key Points
- IS 15778:2007 is a standard set up by the Bureau of Indian Standards (BIS) that applies to CPVC pipes used for hot and cold potable water distribution.
- The norm sets out the requirements for material composition, dimensions, pressure rating, and thermal stability of CPVC pipes.
- The pipes as per this standard shall undergo tests such as hydrostatic pressure, temperature resistance, and durability before they are permitted.
- Production, selling, or importing CPVC pipes in India mandates BIS certification and ISI marking.
- Conformance to IS 15778:2007 is an instrument to prevent pipe failure by leakages and deformation due to high-temperature conditions.
Why is BIS Certification Mandatory | IS 15778: 2007
BIS Certification is required by law in the case of CPVC pipes (IS 15778:2007) in order to maintain safety, good quality, and dependability of hot and cold water plumbing systems. By doing so, it also safeguards against the usage of substandard CPVC pipes and guarantees that Indian regulatory and performance standards are being followed.
Key Points
- BIS certification is a legal prerequisite for the production, sale, or import of CPVC pipes in India.
- It makes sure that CPVC pipes comply with the standards for temperature resistance, pressure resistance, and wear resistance.
- The only CPVC pipes that have received BIS certification are those that are permitted for use in government projects and large-scale infrastructure works.
- In the case of non-certified CPVC pipes, the owners face the risk of fines, seizure of products, and lawsuits under the BIS Act.
- An ISI mark is a guarantee of quality and long-term performance to the buyers and the end users.
