Ammonia Chart

This chart is on the back of the Ammonia Test instructions in the Mini Master Test Kit.

I think that chart is very inaccurate, particularly in its use of color to represent "safe" levels.

Here's a good (if long) read on the effects of pH and temperature (not even mentioned in the above chart) on ammonia toxicity.
