CBR= Caulk Backer Rod filler-does not increase smoke as some fillers do.
Volume was standardized to CCs because of variations in density of powders. Lee dippers were used.
Due to the subjectivity of the test, the inability to calibrate absolutely, and the variations due to weather, light, and conditions, no guarantees are offered or implied that any marginal load (the one below which failure occurred) will pass at any given time. Do not extrapolate data and apply it to similar but not exactly the same powders. For example, Swiss 3F passes with 1.0 CC in the test load. Swiss 2F might or might not pass. if in doubt, increase minimum passing loads by 10-15% margin.
