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.
