As per IS:651 following tests have been selected and recommended by Bureau of Indian Standards :-
Type of Test1. Hydraulic Test
2. Water Absorption Test
3. Acid Resistance Test
4. Alkali Resistan Test
5. Crushing Strength Test
|
Conditions to be FulfilledPipe shall withstand an internal hydraulic pressure of 0.15 MPa on the barrel
Total increase in mass by absorption of water shall not increase 6% upto and including 20mm thickness of pipes. (It increases with the higher thickness of pipes.)
All pipes when tested for acid resistance with Sulphuric acid ( specific strength ) in accordance with the procedure, the loss in mass shall not exceed 2.5%.
The resistance of pipes to alkali is determined by reacting it with Magnesium Sulphate in accordance with the given specified procedure; there shall be no evidence of spitting, softening, spalling or cracking
When tested along the full length of the pipe barrel from shoulder to spigot in accordance with specified procedure, the crushing strength of the pipe shall be not less than 16 kN/m
