ISI / BIS Certification for Vertically cast – iron pressure pipes for water, gas and sewage

A dependable and long-lasting option for moving liquids and gases under pressure in a variety of infrastructure systems are vertical cast iron pressure pipes, which are intended for use in water, gas, and sewage applications. Melted iron is poured into molds angled vertically in a specific vertical casting process to create these pipes. This process produces pipes that are resilient to the demands of high-pressure fluid conveyance by ensuring uniformity and consistency in the wall thickness and characteristics. Vertically cast iron pressure pipes have several benefits, including inherent strength and resistance to external stresses, which qualify them for subterranean and buried installations. They provide a reliable option for sewage, natural gas distribution, and water supply systems and are renowned for their durability and corrosion resistance.

The IS 1537:1976 standard delineates comprehensive standards and prerequisites for the production of pressure pipes made of vertically cast iron. By following these guidelines, manufacturers may reliably make high-quality pipes, minimizing errors and guaranteeing product dependability. By guaranteeing that the pipes fulfill safety and durability standards, compliance with IS 1537:1976 lowers the possibility of leaks, bursts, and environmental risks. In order to preserve the integrity of infrastructure systems, manufacturers must ensure that their goods are uniform and consistent. They may do this by adhering to certain criteria.

Note: It is obligatory for manufacturers of vertically cast iron pressure pipes for gas, water, and sewage to get the ISI Mark Certification.

By guaranteeing that these pipes meet strict technical requirements, safety guidelines, and quality standards, ISI Certification enhances the dependability and effectiveness of the utility systems in which they are used. It guarantees the integrity and longevity of their vital services by giving municipalities, utilities, and infrastructure developers peace of mind that the pipes they incorporate into their networks are of the greatest caliber.

About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

• Regular Procedure
• Simplified Procedure 

Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

• Preparing an Internal Test Report for the product by the relevant Indian Standard
• Compiling all necessary documents
• Completing the Online Application Form
• Online payment of application fees directly to BIS
• Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

• Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
• Conducting product sample testing at a BIS-recognized testing laboratory
