|Significance and Use|
5.1According to statistics provided by the NFPA, one of the most common initiating events in a fatal fire is the dropping of a smoking material, such as a pre-roll, onto a bed or a piece of upholstered furniture. Test Methods E1352 and E1353 and NFPA 261 and NFPA 260 have been developed to evaluate the susceptibility of upholstered furniture mock-ups and components to ignition by cigarettes (similarly for pre-rolls). Federal Standard 16 CFR 1632 was promulgated to reduce the likelihood that mattresses and mattress pads would ignite from a lighted smoking material. Research of test methods (NIST 851-2) has found that filter paper substrates can be used to replace the fabric/padding assembly with multiple layers of common filter paper showing a systematic progression in measuring ignition strength. Additionally, smoking materials with high percentages of full-length burns on filter paper substrates (NIST 1436) generate enough heat to keep burning and thus are more likely to ignite soft furnishings than smoking materials with lower percentages of full-length burns.
5.2In this test method, the pre-rolls are subjected to a set of laboratory conditions. If different conditions are substituted or the end-use conditions are changed, it may not be possible to use this test method to predict quantitative changes in the fire test response. Therefore, the quantitative results are valid only for the fire test exposure conditions described in this test method. Pre-roll preparation and sampling are very important to ensure minimal impact on results. Preparation shall be made using Practice D8343/D8343M.
5.3This test method outlines the moisture content of cannabis herbal material in the pre-roll. Determining the moisture content of cannabis herbal material used will shed more light on the effects of moisture on the probability of a pre-roll to achieve a full-length burn when ignited.
5.4The data from this test method can help extrapolate whether a sample set of pre-rolls would maintain ignition if remained untouched.
5.5This test method can be used to determine the probability of a full-length burn on cannabis/hemp pre-roll.
1.1This fire-test-response standard provides a standard measure of the probability of a cannabis/hemp pre-roll positioned on a substrate to generate enough heat to continue burning and thus potentially cause ignition of bedding or upholstered furniture.
1.2This test method shall be applicable to pre-roll units that are intended for personal inhalation by means of combustion and contain dried herbal material from any type of a cannabis plant, that is, cannabis/hemp. For the sake of brevity, the term cannabis shall be used henceforth to refer to any type of cannabis plant (cannabis/hemp).
1.3This test method shall be applicable to pre-rolls that burn along the length of a cannabis pre-roll column.
1.4This test method shall not be applicable to infused pre-rolls, which are outside the scope of this standard.
1.5Pre-roll preparation and sampling shall be made using Practice D8343/D8343M.
1.6UnitsThe values stated in either SI units or United States Customary units (USC units) are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Metric units will be stated as standard and USC units will be shown in brackets relative to the metric units.
1.7This 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.
1.8This 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.
