IS 7834 (Part 2) : 2000injection moulded PVC socket fittings with solvent cement joints for water supplies, Part 2: Specific requirements for 45 degrees elbows
Link points to Internet Archive / others. Not hosted by InfraLens. Details
IS 7834:2000 (Part 2) is the Indian Standard (BIS) for injection moulded pvc socket fittings with solvent cement joints for water supplies, part 2: specific requirements for 45 degrees elbows. This standard specifies the material, dimensional, and performance requirements for injection moulded PVC caps designed for solvent cement joints in water supply pipelines. It is a part-specific standard and must be read in conjunction with IS 7834 (Part 1) for general requirements and test methods.

Practical Notes
! Always ensure the pressure class of the cap matches or exceeds that of the pipeline it is being fitted to.
! The effectiveness of the cap depends entirely on the correct application of solvent cement; follow manufacturer instructions and general guidelines in IS 7834 (Part 1).
! Check for the ISI certification mark on the fitting to ensure compliance with the standard.

Key Differences
≠IS 7834 specifies pressure classes based on kgf/cm² at 27°C, whereas ISO and EN standards use Nominal Pressure (PN) in bars at 23°C, and ASTM standards use a 'Schedule' system (e.g., Sch 40) with pressure ratings that vary by size.
≠The duration for the Heat Reversion test in IS 7834 is a fixed 30 minutes for most sizes, while in ISO 1452-3, the immersion time is dependent on the wall thickness of the fitting (e.g., 60 minutes for 3-5mm wall thickness).
≠IS 7834 mandates a specific colour of 'dark grey' for the fittings, whereas ISO 1452-3 allows for a range of colours, typically 'grey, blue, or cream'.
≠The reference temperature for mechanical property testing in IS 7834 is 27 ± 2°C, which reflects the standard ambient temperature for India. Most ISO, EN, and ASTM standards use a reference temperature of 23 ± 2°C.
Key Similarities
≈All standards are based on the same primary material: unplasticized polyvinyl chloride (PVC-U), and reference material compound standards to ensure quality.
≈The primary jointing method specified is the solvent cement socket-and-spigot type, ensuring a chemically welded, leak-proof joint.
≈Core performance tests are conceptually similar across all standards, including dimensional verification, short-term hydrostatic pressure (burst) tests, and thermal stability (Heat Reversion/Stress Relief).
≈All standards include an opacity requirement (typically limiting light transmission to ≤ 0.2%) to prevent algae and microbial growth within potable water systems.
