- It prescribes the specifications for Cast And Ductile Iron Pipes drainage pipes and fittings for non-pressure and above-ground installations.
- “It is necessary to determine the composition, size, and production technique for the material in order to have strength and durability
- It is linked with testing for crushing strength, water leakage, and dimension standards in recognized laboratories by BIS.
- It requires quality control, labelling, and traceability as per the BIS ISI Mark Scheme.
- All certified pipes will carry the “ISI” mark to ascertain that they meet Indian norms of quality and safety.
Introduction
BIS Certification for Cast and Ductile Iron Pipes based on IS 1729 ensures that the drainage pipes and fittings utilized for over-ground non-pressure pipeline systems are of the desired quality, performance, and durability in India.IS 1729 is an Important Standard published by the Bureau of Indian Standards and casts the Technical Specifications for the manufacture of Socket & Spigot Pipes under the definition of the standard. BIS Certification under IS 1729 ensures that the drainage pipes are resistant to the safe handling of sewage and are immune to seepage, corrosion, and mechanical action for the purpose of ensuring the expected durability and safety.
What is IS 1729?
IS 1729 is the Indian Standard and is published by the Bureau of Indian Standards (BIS). It specifies the requirements for the material, size, and process involved in the production of cast iron and ductile iron drainage pipes and their fittings for overground non-pressure pipeline systems. It details requirements related to composition, dimensions, method of manufacture, jointing (both socket and spigot), and performance testing related to strength and leakage. The scope of IS 1729 is to provide safe and durable drainage pipes for wastewater and sewage discharge applications for buildings and infrastructure works.
Key Points:
- IS 1729 is an Indian Standard. It is published by the Bureau of Indian Standards (BIS). It is related to cast iron, ductile iron drainage pipes, and fittings.
- The standard applies to over-ground non-pressure pipelines used for sewerage and sewage.
- The standard prescribes requirements pertaining to quality, size, and process of manufacture.
- It describes tests for strength, water tightness, and functional tests.
- It is mandatory to comply with IS 1729 for obtaining a BIS (ISI mark) certification in India.
Why is BIS Certification Mandatory
BIS Certification is a must for ensuring that the cast iron and ductile iron pipes manufactured or supplied within India meet the safety, quality, and performance specification details prescribed under the IS 1729 standard. It helps in avoiding deployment of unfit or non-safe drainage and sewage systems for use by the public and ensures quality in the final products offered in the market. BIS Certification of the cast iron and ductile iron pipes is compulsory and helps generate authenticity among the buyers and authorities regarding its testing in BIS-recognized laboratories and adherence to the regulations of India.
Key Reasons:
- Ensures cast and ductile iron pipes comply with IS 1729 quality and safety standards.
- Prevents the selling and usage of substandard or unsafe drainage pipes.
- This protects public health and infrastructure by making the pipelines leak-proof and strong.
- Makes testing in BIS-recognized laboratories compulsive before approval to market.
- Allows only certified products to bear an ISI mark for building trust and legal compliance.
