ASTM E3050-22

ABSTRACT This specification provides requirements and corresponding test methods for denatured ethanol intended to be used as a cooking or appliance fuel, or both. The addition of a denatonium benzoate and a colored dye is required. The minimum and maximum requirements for the amount in which denatonium benzoate must be added are specified. The hydrocarbons approved for use under this specification are gasoline, unleaded gasoline, natural gasoline, heptane, or rubber hydrocarbon solvent. Also addressed in this specification are workmanship, sampling, sontainers, and sample handling. The test methods cover ethanol, water, and higher alcohols as well as acidity and solvent-washed gum content. SCOPE 1.1 This specification covers denatured ethanol intended to be used as a cooking or appliance fuel, or both. 1.1.1 This product is intentionally denatured as an additional deterrent to consumption and to avoid beverage alcohol use. 1.1.2 This specification allows for various denaturants to be used for the intended purpose of cooking or appliance fuel. Jurisdictions may vary in their regulatory requirement for the allowable or prohibited types of denaturants, chemical composition of the denaturant or concentration of denaturant needed to denature the ethanol. 1.2 Nothing in this specification shall preclude observance of federal, state, or local regulations. 1.3 Denatured ethanol has many regulatory limitations that cover the production, trading, transporting, distributing, wholesale and retail sale, and use of denatured ethanol; this specification does not purport to address the regulatory compliance aspects of these activities. 1.4 The application and intent of this product is for household cooking fuel and not for on-road motor fuel use (see D4806). 1.5 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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.
