CENTRIFUGALLY CAST DUCTILE IRON PRESSURE PIPES IS 8329:2000

BIS CERTIFICATION FOR CENTRIFUGALLY CAST DUCTILE IRON PRESSURE PIPES IS 8329:2000

In today's competitive landscape, maintaining market presence without a certified, high-quality product can be challenging. Obtaining a BIS license may also be essential for selling products in the Indian market. To achieve BIS certification and ensure product quality, manufacturers must adhere to the specified Indian standards.

Let's delve deeper into at IS 8329:2000 of centrifugally cast (spun) ductile iron pressure pipes.

This standard delineates the requirements and relevant test methods for ductile iron pipes and their joints, fabricated in metal (lined or unlined) or sand molds, utilized in pipeline construction.

To convey water, sewage, or gas
Suitable for installation either below ground or above ground
Can be used with or without pressure

This standard additionally outlines specifications for ductile iron pipe materials, including dimensions, tolerances, mechanical properties, as well as standard coatings and linings.

This standard permits the use of alternative joint types or potential future joint innovations, ensuring consistent overall dimensions for safety and interchangeability.

This standard is relevant to pipes featuring socketed, flanged, or spigot ends, intended for jointing with a variety of gaskets not specified herein. These pipes are typically provided with external and internal linings and are designed for fluid temperatures between 0°C and 50°C, excluding frost conditions.

This standard does not address fittings utilized with the pipes specified herein; the specifications for such fittings are outlined in a separate standard, IS 9523. Additionally, fittings compliant with IS 13382 may be used with ductile iron pipes when pressure requirements align.

Pipes are categorized as K7, K8, K9, K10, or K12 based on service conditions and manufacturing methods. Material supply must meet the specifications detailed in IS 1387, ensuring high-quality metal that fulfills the mechanical standards specified in the standard.

TESTS

The subsequent test must be conducted for Centrifugally Cast (spun) ductile iron pressure pipes.

Mechanical test
Brinell hardness test
Dimension and size
Coating
Tensile test

MARKING

Every pipe should display the necessary details specified in the standard, and manufacturers have the option to apply the Standard Mark (ISI Mark). To use the Standard Mark (ISI Mark), manufacturers must obtain a BIS license from the Bureau of Indian Standards. This license is granted after a comprehensive evaluation of manufacturing infrastructure, quality control protocols, testing capacities, and production procedures.

PROCESS FOR BIS ISI MARK CERTIFICATION

BIS CERTIFICATION PROCESS

Acquiring a BIS license requires a comprehensive review of manufacturing infrastructure, quality control abilities, testing resources, and production procedures. This thorough assessment guarantees that products not only adhere to regulations but also prioritize consumer safety and reliability.
