    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 space, which can be implemented in international jurisdictions as this industry progresses. Examples of such standards include, standard test methods for measuring and validating selected temperature settings, the ability or inability for non-desired users to activate or inhale from devices, guides for safe design and manufacturing of cannabis devices, and specifications for convection heating-based vaporizers.

    4.9 Reference to a particular type in this classification is not intended in any manner to denote endorsement or approval of said type by ASTM International.

    1. 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.
