ASTM D8450-22 PDF

Overview

ASTM D8450-22: Standard Specification for Environmental Conditions While Packaging Cannabis/Hemp Flower provides internationally recognized guidelines for controlling environmental conditions - such as temperature, humidity, and lighting - during the packaging of cannabis and hemp flower intended for human use. The purpose of this standard is to ensure the safety, quality, and weight stabilization of packaged flower during indoor packaging operations. It applies specifically to the indoor environments where cured cannabis/hemp flower is moved to consumer or non-consumer packaging prior to storage or transit.

This standard was developed by ASTM Committee D37 on Cannabis and aligns with the World Trade Organization's principles for developing international standards. It is intended for use by licensed operators across the cannabis and hemp industries and does not apply to frozen material or flower intended for extraction.

Key Topics

• Environmental Controls: The standard prescribes specific ranges for temperature and relative humidity to maintain during the packaging process.

  • Temperature during packaging must be maintained between 1 °C and 30 °C.
  • Relative humidity must be controlled according to a defined scale, ensuring the finished packaged product maintains stability and meets water activity requirements.

• Lighting Guidelines:

  • Light exposure, particularly ultraviolet (UV) light, should be minimized to what is necessary for safe and effective packaging.
  • When possible, use UV filters on fluorescent fixtures, and prefer LED fixtures to reduce UV exposure, safeguarding product quality.

• Monitoring and Recordkeeping:

  • Temperature and humidity must be measured using appropriate equipment, with continuous monitoring that may be automated or manual.
  • Records must be maintained to demonstrate compliance, supporting traceability and quality assurance.

• Limitation of Scope:

  • Outdoor packaging conditions, security aspects, and issues related to frozen or extraction material are excluded.
  • The specification remains in effect only until the packaged flower is put into storage or transit.

Applications

Adhering to ASTM D8450-22 is vital for:

• Licensed Cannabis and Hemp Operators: Required for facilities handling the transition of cured flower from processing to packaging for distribution.
• Quality Assurance: Ensures products retain intended potency, aroma, and consumer safety by mitigating risk of mold, degradation, or weight fluctuation due to moisture variation.
• Regulatory Compliance: Supports meeting legal and market requirements for environmental controls during packaging.
• Brand Protection: By controlling environmental conditions, organizations can deliver consistently high-quality products, increasing consumer trust and shelf stability.
• Audit and Traceability: Systematic monitoring and documentation facilitate regulatory audits and quality control reviews.
