IS 10124:2000 is the Indian Standard (BIS) for unplasticized pvc pipes for use in suction and delivery lines of agricultural pump sets. This standard specifies the requirements for unplasticized PVC (uPVC) pipes intended for use in suction and delivery lines of agricultural pump sets. It covers material composition, dimensions, physical and mechanical properties, performance tests, and marking for various pressure classes.

MediumCurrent
PVC-U pipes and fittings for pressure applications
A combined standard for pipes and fittings, which includes specific requirements for fabricated fittings.
ASTM D3139-18ASTM International, USA
LowCurrent
Standard Specification for Joints for Plastic Pressure Pipes Using Flexible Elastomeric Seals
Focuses on elastomeric seal joints, which may be a component of fabricated fittings, but does not cover the fitting itself.
Key Differences
≠IS 10124:2000 uses a reference temperature of 27°C for pressure ratings and testing, reflecting Indian climatic conditions, whereas EN ISO and other international standards typically use 20°C.
≠The Indian standard specifies a limited range of pressure classes (2.5, 4, 6, 10, 12.5 kgf/cm²), which are distinct from the PN (Nominal Pressure) ratings in the ISO/EN system or the Class/Schedule system in US standards.
≠IS 10124:2000 is older and may lack some advanced testing requirements found in newer standards like AWWA C907-20, such as long-term resistance to disinfectants like chlorine and chloramine.
≠Marking requirements are different; IS 10124 mandates the ISI Certification Mark, which is not a requirement in international standards that have their own specific marking protocols (e.g., NSF-pw mark for AWWA).
Key Similarities
≈All standards mandate that fabricated fittings be made from pipe that conforms to a recognized standard for PVC-U pressure pipes (e.g., IS 4985 for IS 10124).
≈The fundamental material requirement across all standards is the use of unplasticized polyvinyl chloride (PVC-U) compound suitable for contact with potable water.
≈Core performance tests such as the short-term hydrostatic pressure test, opacity test (to prevent algae growth), and heat reversion test are common requirements to ensure structural integrity and stability.
≈All standards specify dimensional controls for solvent cement sockets and spigots to ensure proper interference fits and reliable jointing.
