CORROSION TESTING

Corrosion tests

  • Dezincification Tests
  • Salt Spray Tests
  • Other
  • Salt Spray Corrosion tests as per ASTM B 117 IS : 101 & ISO : 9227, JIS : -IS
  • Neutral salt spray test (NSS)
  • Acetic salt spray test (ASS)
  • Copper Acetic Salt spray test (CASS)
  • Humidity tests @ 95 % R.H, 40 to 50 °C

SALT SPRAY CORROSION TESTING

 RANGE OF CAPACITY

  • Chamber 1 (1000 *700*700)
  • Chamber 2 ( 1200 * 700 *700)
  • Chamber 3 ( 1200 * 900 * 900)

PROPERTIES DETERMINED

  • Neutral salt spray test (NSS)
  • Copper accelerated acetic acid salt spray (CASS)
  • Acetic acid salt spray (AASS)

INTER GRANULAR CORROSION TESTS

 RANGE OF CAPACITY

  • IGC practice –A
  • IGC practice –B
  • IGC practice –C
  • IGC practice –E
  • IGC practice –F

PROPERTIES DETERMINED

  • Step, Dual or Ditch structure classification after electrolytic

oxalic acid etching

  • Corrosion rate after 120 hours (practice-B)
  • Corrosion rate after 48 hours * 5 boils (practice-C)
  • Examination at 20X on the 180 degree bend surface

FAILURE ANALYSIS STUDIES 

  • Root cause investigation of failures in engineering
  • components through systematic investigation.
  • Lab collects the maximum amount of information from failed components through various available techniques & tries to correlate one another to conclude with expert opinion.
