I'm currently conducting some testing related to indoor pool environments. Here I believe, airborne chloramines are responsible for stress corrosion cracking in austenitic stainless steels.

Unfortunately, I do not know how to generate the said chloramines for testing purposes.My setup so far includes a sealed container in which I can suspend samples over hydrous chlorine (~ pH 7.4) similar to pool areas. This container also has a clear lid with reflective panels aimed at it, to act similar to a box-type solar cooker (adding heat to increase humidity and accelerate corrosion).

From my basic research chloramines are measured as free (elemental) chlorine plus ammonia compounds (urea/carbamide). In my basic (pardon the pun) understanding, I thought the addition of hydrogen peroxide (urea) or Cloudy Ammonia would create chloramine(s). However, I've now found a thread that states hydrogen peroxide REMOVES chloramines from water.

Send help! (I know chloramines in pools are created by bodily fluids, please don't make me sh!t in a bucket at work...)

I think I've figured it out, whilst not a complete answer it's got all the important bits. This summary of chlorine action in pools has really pulled my admittedly simple research together. Looks like I just need to get some aqueous ammonia and we should be off to a good start.

Chloramine Production

Seems like I was barking up the wrong tree on the Hydrogen Peroxide front. Or I've just confused myself and they're kind of the same (still unsure how 'urea' fits in TBH)
