IEC 60754-1
« on: July 08, 2017, 11:39:56 AM »
Dear all, As per IEC 60754-1,what formula used for identifying the amount of halogen acid gas generation? Actually it is  = 36.5*(B-A)*M*1000/200/m mg/gram. B -ammonium thiocyanate blank test value,A-tested solution value,M-molarity of ammonium thiocyanate solution,m-mass of samplei did that test with LSZH sample,ammonium thiocyanate blank test value is-20.8 ml,tested value is 19.8ml ,mass of sample 899 mg.i applied these values in above formula but observed answer in % is 2.030 % .But required answer is >0.5%.Let me know what mistake I have done.
