Область применения

This standard applies to alcohol base liquid fuel formulated primarily from alcohols. It establishes the requirements, testing methods, sampling, and labeling for these fuels, which are typically used in compatible domestic or commercial cooking appliances. It is mandatory for manufacturers producing alcohol-based synthetic liquid fuels for the Chinese market.

Технические требования

The standard mandates that the fuel must be a uniform, transparent liquid without any offensive odor. It categorizes the fuel into two quality tiers (Tier 1 and Tier 2) based on specific physical and chemical parameters. Key technical parameters regulated include alcohol content, density, mechanical impurities, and pour point. Additionally, the standard sets strict limits on ignition temperature, pH value, and the 50% distillation temperature to ensure safe handling and efficient combustion. Environmental and performance metrics such as total sulfur content and low heating value are also defined to differentiate between the quality tiers. Crucially, the standard imposes formulation restrictions to ensure safety and environmental compliance. The fuel formula must not contain any inorganic salts, halogenated hydrocarbons, or nitro compounds, and the aromatic hydrocarbon content in any added hydrocarbons must be strictly controlled. The fuel must also demonstrate stability at low temperatures (-20°C) without stratification.

Методы испытаний

The standard outlines various testing procedures to verify compliance, referencing several GB/T methodologies. Key tests include visual inspection for appearance, a simplified method for alcohol content, and density measurement per GB/T 611. Mechanical impurities and pour point are tested according to GB/T 511 and GB/T 510, respectively. Thermal and combustion properties are evaluated through ignition temperature testing (referencing GB/T 5332), 50% distillation temperature measurement, and low heating value determination via the oxygen bomb calorimeter method (GB/T 384). Chemical stability and safety are assessed through total sulfur content testing (GB/T 11131), low-temperature stability (GB/T 6986), and a specific formaldehyde test using a fuchsin-sulfurous acid solution. Manufacturers must conduct factory inspections on nine specified parameters before products can be released.

Частые вопросы

What products are regulated under GB 16663-1996?

The standard applies to liquid fuels formulated primarily from alcohols. It is designed to be used in conjunction with the industry standard for Alcohol-based Liquid Fuel Domestic Cooking Stoves.

Are there any specific formulation restrictions in GB 16663-1996?

The standard strictly prohibits the addition of inorganic salts, halogenated hydrocarbons, and nitro compounds. Additionally, any hydrocarbons added to the formula must have an aromatic content of less than 40%.

How does GB 16663-1996 categorize the fuel quality?

The standard classifies the fuel into two quality tiers, Tier 1 and Tier 2, primarily differentiated by their low heating values and total sulfur content limits. Manufacturers must declare and meet the specific tier requirements for their product certification.

The summary above provides a high-level overview of GB 16663-1996.
