Suitability test of Shrinkin'Sleeves for  

  • Continuous operating temperature.
  • Long duration testing at high temperature

Sample Description:

  • Cut lengths of Shrinkin'Sleeves to be tested.
  • Sleeves under test, shrunk on appropriate mandrel.

Procedure: Cut lengths of sleeves/sleeved mandrels progressively exposed to various temperatures, durations in the oven. The results observations are tabulated after removal of test samples from oven.


Test Specified : Expose test samples to following parameters. a)Continuous operation


Temperature: 100oC x 1000 hrs. Long duration testing at higher temperature : 110oC x 24 hrs.

Observations

  • The shrinkage should be even from all sides.
  • The surface, smooth all over without pit marks / pin holes
  • The sleeving should not develop any crack.
  • The sleeving retains all its properties after cooling.

Inference:

  • Shrinkin'Sleeves can be used at an elevated temperature of 100oC for 1000 hours.
  • Shrinkin'Sleeves have got a capacity to bear a heat shock Upton 110oC for 24 hours.

Sample Description : Cut lengths of "Shrinkin'Sleeves".

Apparatus

  • Ignition chamber : Corning / Pyrex glass, dia. 75 mm x 450 length.
  • Ignition source : Bunsen burner, placed in a fume cupboard.

Procedure :

  • Clamp an appropriate size & length of "Shrinkin'Sleeves" in a holder & fix it into the ignition chamber.
  • Light the ignition source under normal Oxygen conditions.
  • Bring the test sample in the ignition zone.

Observations :

  • After shrinkage test sample gets ignited in the ignition zone.
  • There is no droppage of any melt during ignition.
  • Test sample withdrawn out of ignition zone or the ignition source put off, the ignition of test sample ceases immediately.
  • The ignited material leaves granular ash.

Inference : "Shrinkin'Sleeves" are self extinguishing with no droppage of any melt during ignition.
