- Mandatory Indian Standard: IS 15909 for BIS CERTIFICATION FOR POLY VINYL CHLORIDE GEOMEMBRANES IS 15909. They are governed based on requirements as prescribed by Bureau of Indian Standards.
- Material & Manufacturing Requirements :Defines the quality of the PVC resin, additives, thickness, and surface quality for impermeability and durability.
- Performance Testing: Tests include the measurement of tensile strength, elongation, resistance to punctures, seam strength, and water permeability.
- Application Suitability: Certified Geomembrane PVCs can find application in the waterproofing of canals, reservoirs, ponds, landfills, and other civil engineering structures like tunnels.
- ISI Mark Authorization: The authorization to use the ISI mark shall be limited to those manufacturers who are approved and licensed from the BIS. The ISI mark indicates compliance and acceptability in the Indian market.
Introduction
BIS Certification for Poly Vinyl Chloride (PVC) Geomembranes, as mentioned under IS 15909, ensures that the PVC geomembranes made for waterproof lining are as per Indian standards for quality, safety, and performance. This is a stamped certificate provided by the Bureau of Indian Standards, meaning that it is a sign for the public that the product is as per norms for material, thickness variation, strength, durability, and watertight conditions. BIS-certified PVC geomembranes are the most suitable for canal lining, reservoirs, landfilling, ponds, as well as any other civil works, as they ensure that the projects perform well as per Indian standards.
What is IS 15909?
IS-15909: This Indian Standard was published by the Bureau of Indian Standards. This standard specifies requirements for PVC Geomembranes used in waterproofing operations. The specification includes the requirements of the resulting waterproofing work relating to the Composition, Thickness, Strength, Durability, Impermeability, and Performance of the PVC geomembrane. The requirements mentioned in the specification will make the PVC geomembrane applicable to Canal, Reservoir, Pond, Landfill, Tunnel, and Civil structures. The standard, IS 15909, will provide the required quality and efficiency to the PVC geomembrane in the market.
Key Points:
- Indian Standard: For the purpose of the above consideration, the relevant Indian standard is IS 15909. The aforementioned standard is published by the BIS.
- Material Specifications: These are the specifications concerning the quality of the PVC resins used, the additives in the materials, thickness, and finish.
- Performance Tests: Tests involving tensile strength, elongation, resistance against punctures, strength of seamed joints, and water permeability.
- Application Range: Applied in canal, reservoir, pond, dumpsite, tunnel, and other engineering constructions.
- Quality Assurance Function: Ensuring the strength, water resistance, and durability of the PVC Geomembranes offered to the Indian environment
Why is BIS Certification Mandatory
It is basically required for ensuring the adherence of products to the prerequisites of Indian standards prescribed by the Bureau of Indian Standards covering the product’s quality, safety, and performance. It saves consumers and infrastructure projects from inferior quality material, helps the administration in regulatory compliance, standardizes quality consistency across the different manufacturers, and legally only those certified products can be manufactured, sold, or used in the Indian market.
Key Reasons:
- Quality Assurance: The products and materials conform to the quality, strength, and durability standards as specified in the Bureau of Indian Standards.
- Consumer & Public Safety: Safeguards consumers and public safety against any kind of hazard caused by low-quality or unsafe items.
- Legal Compliance: Mandatory for legal manufacturing, importing, and selling notified products in India.
- Market Credibility: It promotes the credibility and acceptability of certified products within the Indian market environment.
- Uniform Standards: This fosters a degree of standardization.
Importance and Benefits of BIS Certification
