Standard Guide for Sample Preparation of Cannabis and Hemp Inflorescence for Laboratory Analysis

2023-02-10 /Active
Idiomas Disponibles:

1.1 In this guide, the basic steps in obtaining a test portion sample of either dried cannabis/hemp inflorescence are outlined.

1.2 Sample preparation depends on many factors including moisture (dryness) of the sample, the analyte to be measured, the concentrations/amounts, and the test method's precision and accuracy requirements. In this case, dried cannabis or hemp plant material require particle size reduction-comminution from a representative sample of which the final analytical testing portion is determined by the employed testing method. Local regulatory guidelines often dictate both the representative sample that is taken from the bulk material (harvest batch) and the final mass of the test portion (for example <1 g) for chemical analyses.

1.3 This guide will not purport to meet every local and state jurisdiction since different regulatory requirements vary; the local/state requirements are at the discretion of the user to follow and interpret.

1.4 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
