I agree with Spaceman here. If you can perform a personal
demonstration and get an inspector to sign off based on that it will
be optimal for you.
If you need to get official lab testing performed, I see two
alternatives.
1. Take a sample (or few) that you've created to the lab and let
them conduct whatever tests are appropriate on that and get a written
report that you can file with your building department.
2. Give the lab your recipe, mixing instructions, and drying
instructions. They can then perform their tests on samples that they
have created themselves.
Option 1 will be the simplest and likely the cheapest. However, the
lab will only be able to document how the sample that you gave them
performed. They won't be able to offically verify what is in the
sample. It will not be practical for them to confirm that the
contents of your samples are what you claim. This has the
disadvantage that your testing will only be valid for your own use.
It will be difficult for others to take a copy of your lab testing
and use it elsewhere.
Option 2 will be far more univeral but will be more difficult and
probably more expensive. Since the lab will be able to document the
contents of their own samples, they will be able to claim that anyone
that creates a block using the same ingredients and techniques should
get similar performance. This will be a vastly easier report for
others to take advantage of.
What you choose to do is clearly your choice. I encourage you to AT
LEAST ASK THE LAB about what they would charge for option 2. You
just might happen to find a lab that will perform option 2 for
minimal extra expense.
Food for thought.

I have never seen any lab reports on papercrete smoldering, just
strength tests. Why not take a pc panel and a 2x4 and drywall panel,
and a torch, and do the test, maybe in his presence? He's a state
inspector, right? Did he give you an idea of what he would consider
acceptable "lab data"? Maybe something from NMSU would satisfy him.

Does anyone have "official" flammability data for papercrete? I have
been asked by my building inspector to present lab data for
flammability. Ideally I would see this as a mix chart of sand/clay/
cement/borons to paper ratios. I see plenty of web pages showing the
1:1 ratio of paper to cement will smolder. Even more stating the 1:4
ratio of paper to cement will not burn. I am just looking for
something to take away liability from my building inspector.
