Work Item
ASTM WK71840

New Practice for sample preparation of cannabis and hemp inflorescence for analysis.

1. Scope

The development and maintenance of standards and guidance materials for cannabis and its products and processes. The work of this committee will be coordinated with other ASTM committees and other organizations having mutual interest.


sample preparation, homogenization, grinding, milling, sampling, cryogenics


All analyses start with some form of sample preparation and homogenization of a proportionate sample. Many approaches exist between mechanical grinding, ball mills (wet and dry grinding) and cryogenic grinding of the sample for testing purposes. In addition many different devices and equipment can be used with the resulting sample consistency varying based on the approach taken.

The title and scope are in draft form and are under development within this ASTM Committee.
