Understanding IS 14151 PART-1: 1999 Standards
This specification consists of following tests and their requirements as per IS 14151 (Part 1) : 1999 (Reaffirmed 2021)
- Visual Appearance- The internal and external surface of the pipe shall be smooth, clean and free from grooving, pit marks and melt fractures.
- Dimensions, mm- Measured by using vernier caliper and pi tape
- Density at 27°C, kg/m³-940.0 – 958.4
- Carbon black content, %-2.5± 0.5
- Carbon black Dispersion-Shall be satisfactory
- Reversion, %-±3
- Melt flow rate, g/10 min (at 190°C, 5 kg)-0.2-1.1
- Tensile Strength , MPa-19 Minimum
- Hydraulic Characteristic At induced stress 3.8MPa and 80°C for 48 hrs.-Shall not show signs of localized swelling, leakage or weeping and shall not rupture during the prescribed test duration.
Material : The percentage of anti-oxidant in the base resin shall not be more than 0.5 percent by mass. The carbon black content in the material shall be within 2.5± 0.5 percent and the dispersion of carbon black shall be satisfactory
Reworked Material : Addition of not more than 10 percent of the manufacturer’s own rework material produced during the manufacture and works testing of pipes complying with this standard is permitted. No other rework material shall be used.
PERFORMANCE REQUIREMENTS :
When subjected to internal pressure creep rupture test in accordance with the pipes shall show no signs of localized swelling, leakage or weeping, and shall not rupture during the prescribed test duration. The temperature, duration of test and stresses for quality and acceptance test shall be as given in Table
The tensile strength and elongation at break at 27°C for different thicknesses of the pipes shall
be as follows:
Selection of Test Piece based on wall thickness of pipe
Test Piece Type 1/2
Details of test piece dimensions given in below figure
Test Piece Type 1
Test Piece Type 2
SUPPLY OF PIPES
The pipe length excluding coupler attachment shall be either 3 m or 6 m ~ 0.01 m for shiftable sprinkler systems or as coils with a minimum inner diameter of 25 times the outer diameter of the pipe. The pipes may also be supplied in other lengths where so agreed to between the manufacturer and the purchaser. The ends shall be cut at right angles to the pipe axis.
Marking of Pipe
Class 1 – Orange
Class 2 – Red
Class 3 – Blue
Class 4 – Green
