Standard Test Method for Measuring the Probability of a Full Length Burn on a Cannabis/Hemp Pre-roll

Importancia y uso:

5.1 According 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.

5.2 In 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.

5.3 This 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.

5.4 The data from this test method can help extrapolate whether a sample set of pre-rolls would maintain ignition if remained untouched.

5.5 This test method can be used to determine the probability of a full-length burn on cannabis/hemp pre-roll.
