Standard Classification for Cannabis/Hemp Flower Vaporizers
SIGNIFICANCE AND USE
4.1 This classification defines various types of cannabis flower vaporizer devices.
4.2 This classification shall be applicable to any vaporizer devices intended to be used to facilitate the vaporization of cannabis flower intended for inhalation, regardless of the type of cannabis plant from which the flower was derived. There is no distinction between flower intended for inhalation from a cannabis plant that can be classified as “hemp” and flower that cannot, other than the delta-9-THC content.
4.3 The purpose of this classification is to standardize the naming of device types under the classification.
4.4 The classification system breaks the device types into three main categories and three subcategories. These are intended to aid buyers and sellers of these devices in accurately defining the products they are buying or selling. This classification system shall also aid in the understanding of the various types of cannabis flower vaporizing devices that exist in the marketplace by reducing them down to their most common denominator: are they handheld or desk top or other “X”, and are they manual, electronic or distinct.
4.5 This classification will provide clarity to industry, government, and the public on terminology, and the intended product usage of cannabis flower vaporizers.
4.6 This classification standard provides a uniform set of usage definitions within the cannabis industry. Included within this classification is a set of figures that outlines some individual components and aspects of various types of cannabis flower vaporizers.
4.7 This classification is not intended to define all terminology, design, mechanical, physical, or universal functions and impacts of different technologies attributable to cannabis flower vaporizers. Such characteristics and category details and nomenclature will be defined in Guide D8373.
4.8 Additional specifications, guides and test methods should be created to further international standards in this sp...
SCOPE
1.1 This standard shall classify various types of cannabis/hemp flower vaporizer devices.
1.2 This classification differentiates between the intended use of each type of cannabis/hemp flower vaporizer devices.
1.3 This classification shall provide examples of each type of cannabis/hemp flower vaporizer devices. Examples and pictorials shown in the annexes and appendixes or described in this classification are not intended to be all-inclusive and are included only as an aid in understanding and comprehension of the classification system.
1.4 Vaporizer devices intended for use with materials other than cannabis flower, a dried cannabis flower, or ground dried cannabis flower, or combination thereof, are not in the scope of this classification.
1.5 This classification shall apply to vaporizer devices used to consume cannabis flower from a cannabis plant regardless of the type of cannabis plant from which it is derived. For the sake of brevity, the term “cannabis” shall be used from now on to refer to any type of cannabis plant (cannabis/hemp).
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 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.
1.8 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.

Overview
ASTM D8357-21: Standard Classification for Cannabis/Hemp Flower Vaporizers is an international standard developed by ASTM International to establish a uniform classification system for cannabis and hemp flower vaporizer devices. This standard applies to all types of vaporizer devices designed to facilitate the vaporization of dried cannabis flower for inhalation purposes, regardless of the type of cannabis plant (including hemp). The standard helps the cannabis industry, regulators, and consumers clearly identify and differentiate between various vaporizer types, streamlining product communication and compliance.
Key Topics
- Classification System: Vaporizer devices are categorized by intended use and design, with a primary focus on personal consumption devices.
- Main Categories:
- Handheld
- Desktop
- Other (“X”)
- Subcategories:
- Electronic Vaporizer (integrates a heat source)
- Manual Vaporizer (external heat source required)
- Distinct Vaporizer (devices not classified as electronic or manual)
- Main Categories:
- Terminology: The standard defines key terms relevant to cannabis flower vaporizers, including cannabis flower, dried cannabis flower, ground dried cannabis flower, kief, and vaporizer.
- Intended Scope: Devices covered are strictly intended for cannabis flower (dried or ground) inhalation. Vaporizers designed for other materials or extracts are beyond the scope.
- Purpose: To promote clarity and consistency in industry communication and transactions through standardized nomenclature.
- Examples and Figures: The standard includes references to typical examples and component descriptions, supporting comprehension and correct application.
Applications
Adopting ASTM D8357-21 provides significant practical value across the cannabis and hemp vaporizer market:
- Manufacturers and Sellers: Enables precise labeling and product descriptions, reducing ambiguity in the marketplace. Clear categorization assists buyers in selecting the correct device for their needs.
- Regulatory Compliance: Supports government agencies and regulatory bodies by offering a uniform basis for product classification, facilitating standard enforcement and oversight.
- Industry Consistency: Fosters a universally understood language within the cannabis sector, smoothing trade, import/export, and commercial agreements.
- Consumer Transparency: Helps consumers make informed purchase choices based on the intended use and operation of vaporizers (e.g., whether the device is handheld or desktop, electronic or manual).
- Future Standardization: Provides a foundational framework for developing additional guides, specifications, and test methods relating to cannabis vaporizer safety, performance, and user protection.
Related Standards
For comprehensive compliance and integration, reference to related ASTM standards is recommended:
- ASTM D8270: Terminology Relating to Cannabis - covers broader cannabis industry terminology.
- ASTM D8373: Guide for Cannabis/Hemp Flower Vaporizers - elaborates on further nomenclature, design details, and category definitions.
- World Trade Organization TBT Committee Principles: This standard follows internationally recognized principles for standardization, supporting global acceptance.
Summary
By classifying types of cannabis and hemp flower vaporizers, ASTM D8357-21 establishes a clear and consistent approach for industry stakeholders, enhancing product transparency, regulatory alignment, and consumer understanding. Implementation of this cannabis vaporizer standard ensures a harmonized language across the industry, enabling fair trade, quality assurance, and ongoing development of best practices. For businesses and regulators involved in the cannabis consumption device sector, ASTM D8357-21 offers a reliable, internationally aligned framework for device classification and communication.
