Create an R&D protocol designed with the end goal of establishing unbiased R-value and Fire Resistance data that can be used to create a performance specification for hempcrete insulation. This working group shall work with the R-value and Fire Resistance Test Method Evaluation Working Group (WK70549) to define the test methods that shall be used in the R&D protocol. This working group shall work with ASTMs Inter Laboratory Studies (ILS) program to coordinate the testing effort and perform the data analysis. This group shall also work with other ASTM technical committees and organization having a vested interest.

Hempcrete is an eco-friendly construction material that can be made into an insulation material. The process for manufacturing hempcrete varies from region to region making it difficult, if not impossible, to create a specification for the composition of this material. Therefore, a performance specification is necessary to qualify the insulative properties of a hempcrete insulation material. Performance specifications will allow for hempcrete manufacturers to produce hempcrete in any way they see fit using any number of aggregates or binders, and make it easier for hemp-building projects to get permitted and pass inspection, so long as the hempcrete meets the insulation performance specification. This working group will generate the unbiased data necessary to establish the average R-value and Fire Resistance of hempcrete insulation that shall be used as the foundation for a hempcrete insulation performance specification.
