Reading Time: 4 minutes

In the present scenario, it is not easy to survive in the market without a standard certified & quality product. BIS Certification may also be required to sell products in the Indian market. To obtain BIS Certification, the manufacturer must ensure that their product must follow the specified Indian standard. Let’s take a look at IS 8329:2000 of centrifugally cast iron pipes. This standard classifies the requirements & associated test procedures for cast ductile iron pipes and their joints manufactured in metal (unlined or lined) or sand moulds for the construction of pipelines to convey water, gas or sewage, to be installed either above ground or underground, can be used with or without pressure. This standard also specifies requirements for cast iron pipe materials, tolerances and dimensions, mechanical properties, and standard coatings and linings. This standard doesn’t restrict the use of other kinds of joints or future developments of other joints, as long as overall dimensions are kept consistent for safety & interchangeability. The standard applies to cast iron pipes manufactured with flanged, socketed, or spigot ends for joining with several kinds of gaskets that are not covered by this standard and that are normally delivered internally & externally lined and suitable for fluid temperatures ranging from 0˚C to 50˚C, excluding frost. This blog will discuss the BIS ISI Certification for Centrifugally Cast Iron Pipes in India.

What is BIS ISI Mark?

The Indian Standards Institute, the National Standards body renamed the Bureau of Indian Standards in 1987, is known as ISI. The Bureau of Indian Standards provides producers with the ISI mark as a standard mark for a variety of products. Since 1955, the ISI Mark has been regarded as a symbol of reliability, safety, and purity. The ISI mark has been used as a compliance mark for industrial goods. It confirms that the item complies with Indian Standards (IS) set by the Bureau of Indian Standards (BIS). Obtaining the BIS ISI mark[1] for any product that meets Indian Standards requires an ISI Certification process. Electric irons, room heaters, air conditioners, stoves, freezers, electric cables, and other goods, including UPVC pipes, rubber and leather footwear, composite cement, different acids, etc., need to have the ISI mark.

Types of Manufacturing Units of Centrifugally Cast Iron Pipes for Water, Gas and Sewage

There are two types of manufacturing units covered in this BIS Certification for Centrifugally Cast Iron Pipes are:

  • Pipe Casting Units: Manufacturing units that have production/manufacturing capacity to produce said centrifugally cast (spun) iron pipes for water, gas, and sewage, according to IS 8329.

 In the case of pipe casting units, the raw material shall be ductile iron or spheroidal graphite iron of good quality.

  • Flanging Casting Units: Manufacturing units that do not have production/manufacturing capacity to produce said pipes and procure said pipes from the pipe casting units. They then carry out flanging operations to produce flanged DI pipes.

In the case of flanging casting units, the manufacturers must procure only BIS Standard Marked (ISI-marked) pipes from manufacturing unit(s) holding valid BIS licenses as per IS 8329. These flanging units shall also maintain appropriate records of purchase and consumption of ISI-marked DI Pipes.
