6.0 TEST

6.1 Hammer test: Each pipe when tested for soundness by striking with a light hand hammer shall

emit a clear ringing sound.

6.2 Hydraulic test : If so required by the purchaser, pipe shall be tested hydraulically at a pressure

of 0.4 kg/cm2 without showing any sign of leakage, sweating or other defect of any kind. The

pressure shall be applied internally and shall be maintained for not less than 15 seconds. The

tests shall be conducted before coating of pipe.

7.0 Inspection

All tests and inspection shall be carried out at the place of manufacturers unless otherwise

agreed by the purchaser and the manufacturer at the time of purchase. A manufacturer shall

afford the inspector representing the purchaser or third party nominee all reasonable facilities

without charge to satisfy that the materials are being purchased as per specification. The

purchaser reserves the right to have the test carried out at his cost by an independent agency,

whenever there is dispute regarding the quality of materials supplied. All incoming

consignment shall be checked at stores.

8.0 Coating

Normally pipes, unless specially ordered, shall be supplied free of coating on surfaces.

9.0 Marking

Each pipe shall have the Trade mark of the manufacturer and nominal size suitably marked on

it. The pipe marked with the ISI certificate mark, shall be preferred. The equipments shall be

marked with name of manufacturer, year and name of project.
