IS 15307:2003 is the Indian Standard (BIS) for polypropylene (pp) pipes for hot and cold water supplies - specification. This standard specifies the requirements for Polypropylene (PP) pipes intended for hot and cold water supplies. It covers material characteristics for three types of PP (PP-H, PP-B, PP-R), pipe dimensions based on pressure classes, physical and performance requirements like pressure resistance and thermal stability, and marking guidelines for product identification.
Specifies requirements for polypropylene pipes used for hot and cold water distribution systems within buildings.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! PP-R (Polypropylene Random Copolymer) is the most commonly used type for residential hot and cold water plumbing due to its superior temperature resistance.
! Ensure pipes and fittings are from the same manufacturer and material type to guarantee compatibility and effective socket fusion jointing.
! Always check for the ISI mark and the full marking as per Clause 10 on each pipe, which includes manufacturer, size, pressure rating, and material type.

Standard Specification for Pressure-rated Polypropylene (PP) Piping Systems

Key Differences
≠IS 15307 specifies three types of PP: PP-H (Type 1), PP-B (Type 2), and PP-R (Type 3). Modern international standards like ISO 15874 focus almost exclusively on PP-R, PP-B, and the more advanced PP-RCT for hot water applications due to superior long-term thermal stability.
≠IS 15307 uses a design stress (σs) approach for pressure calculations. ASTM F2389 uses a Hydrostatic Design Basis (HDB) determined via long-term testing as per ASTM D2837, which is a fundamentally different methodology for establishing pressure ratings.
≠The Indian standard is based on metric dimensions exclusively. ASTM F2389 provides specifications for both metric and US customary units (Iron Pipe Size - IPS), leading to incompatibility in pipe dimensions and fittings between the systems.
≠IS 15307 specifies a fixed maximum Melt Flow Rate (MFR) for PP-R (≤ 0.5 g/10 min). ISO 15874 is more performance-based, requiring that the MFR of the finished pipe does not deviate more than ±30% from the value specified for the raw material, allowing for more flexibility.
Key Similarities
≈All standards (IS, ISO, DIN) are based on the same fundamental material types: Polypropylene Homopolymer (PP-H), Block Copolymer (PP-B), and Random Copolymer (PP-R), forming a common technical foundation.
≈The principle of classifying pipes based on their pressure-bearing capacity using the Standard Dimension Ratio (SDR) or the related S-Series is a common feature across IS 15307, ISO 15874, and DIN 8077.
≈Core test methods for ensuring pipe quality and performance are highly aligned, including long-term hydrostatic strength (hoop stress test), longitudinal reversion, and opacity tests.
≈Both IS 15307 and ISO 15874 require a minimum Oxidation Induction Time (OIT) of 20 minutes at 210°C for PP-R pipes, indicating an identical requirement for thermal stability and antioxidant content.

What are the different types of PP pipes specified in this code?+
The code specifies three types: PP-H (Homopolymer), PP-B (Block Copolymer), and PP-R (Random Copolymer) (Clause 4.1).
What is the maximum allowed change in length (reversion) for PP pipes when heated?+
The longitudinal reversion shall not be more than 2 percent when tested as per the method in Annex B (Table 3).
Is there a standard color for these pipes?+
No, the color of the pipes shall be as agreed to between the purchaser and the manufacturer (Clause 5.4).
How are these pipes classified for pressure rating?+
Pipes are classified by pressure rating (e.g., PN 10, PN 16, PN 20) which corresponds to a specific Standard Dimension Ratio (SDR) and material type (Table 1).
