Cannabis Sample Requirements
for a Compliance Test
Sampling & Preparation
Here you will find established methodologies for preparing a compliance testing sample.
These methods vary slightly based on the intent of the test (e.g. detecting pesticides, potency, or macrobiotics).
Cannabis Flower Batch
| Weight (in grams) | Batch Testing | Sample Size (g) |
|---|---|---|
| < 4,535.92 | < 10 Pounds (lbs) | 16g |
| 4,581.28 - 9,071.85 | 10.1- 20 Pounds (lbs) | 16g - 32g |
| 9,117.21 - 13,607.8 | 20.1- 30 Pounds (lbs) | 32g - 48g |
| 13,653.13 - 18,143.7 | 30.1- 40 Pounds (lbs) | 48g - 64g |
| 18,189.05 - 22,679.6 | 40.1- 50 Pounds (lbs) | 64g - 80g |
Note: Exact Sample Size = Total Grams x 0.003525, then round up the result.
(Example: 16 lbs = 7,257.48 grams x 0.003525 = 25.583, round up to 26 grams)
