Re: [MW:11608] Deflection test

Are the bonders qualified as per code?   In gre the test coupon is subjected to burst test to qualify bonder.

Prior HT check method of statement & HT procedure should include holding time, it shall be min 2 hrs @ 1.5 times n over 1.25 times for next 2 hrs / upto 24 hrs as in gre u can find seepage/ sweating at the joint n again it depends on test location n owner requirements. There may not be a deflection test post fabrication for gre

Dear experts,               Kindly share your experiences of above test. What is deflection test and when is it performed? I am witnessing GRE piping installation and what are the documents required prior to test? Is it performed before hydro test or after? How do we accept incase of deviations? Should I insist to provide method of statement from the contractor?   Regards Ilangkumaran
