適用範囲

This standard applies to marine fuel oils derived from petroleum, specifically designed for ocean-going and inland river marine diesel engines and their associated boilers. It covers four categories of distillate fuels (DMX, DMA, DMZ, DMB) and six categories of residue fuels (RMA, RMB, RMD, RME, RMG, RMK). It is mandatory for all manufacturers and suppliers of marine fuels operating in the Chinese market. The standard also applies to similarly constructed stationary diesel engines and other marine machinery.

技術要求

The standard specifies stringent physical and chemical properties for marine fuels. For distillate fuels, it defines limits for kinematic viscosity, density, cetane index, and flash point, which must be at least 60°C. A critical requirement is the sulfur content, which is categorized into three tiers (I, II, III) to comply with international emission control area (SECA) regulations. Fuels must be free from inorganic acids, used lubricating oils (ULOs), and any added chemical waste or harmful substances. For residue fuels, the standard outlines parameters for viscosity, density, and the Calculated Carbon Aromaticity Index (CCAI) to ensure proper ignition and combustion quality. It also sets strict limits on trace metals such as vanadium, sodium, aluminum, and silicon, which can cause high-temperature corrosion and engine wear. Suppliers must ensure that residue fuels meet the minimum net calorific value requirements to guarantee adequate energy output. Additionally, the standard addresses the presence of Fatty Acid Methyl Esters (FAME). Distillate fuels must not contain FAME beyond a "trace" level (up to 0.5% volume fraction for clear fuels), and intentional blending of biofuels is strictly prohibited. Manufacturers must ensure that fuels do not contain any substances that could jeopardize ship safety or increase air pollution.

試験方法

The standard mandates specific testing procedures to verify compliance. Key evaluations include kinematic viscosity and density measurements using GB/T 265 and GB/T 1884/1885. Sulfur content is determined via X-ray fluorescence spectrometry (GB/T 17040). Flash point is tested using the Pensky-Martens closed cup method (GB/T 261). For residue fuels, total sediment is assessed using hot filtering and aging methods, while trace metals like vanadium and sodium are quantified using inductively coupled plasma emission spectrometry (IP 501).

よくある質問

What products are regulated under GB 17411-2015?

GB 17411-2015 is a mandatory national standard that applies to marine fuel oils used in ocean-going and inland river marine diesel engines and their boilers. It covers four categories of distillate fuels and six categories of residue fuels, along with specific grades for inland river applications.

What are the main updates from the previous GB/T 17411-2012 version?

The standard was upgraded from a recommended to a mandatory status. Key updates include the addition of a three-tier sulfur content classification for both distillate and residue fuels, an increase in the minimum flash point for DMX distillate fuel to 60°C, the introduction of net calorific value requirements for residue fuels, and the inclusion of specific requirements for inland river marine fuels.

How does GB 17411-2015 differ from the international standard ISO 8217:2012?

GB 17411-2015 is modified from ISO 8217:2012. It incorporates specific Chinese national testing methods and adjusts technical parameters to align with domestic market conditions and international maritime regulations, such as stricter sulfur content limits and specific requirements for inland river vessels, which are not covered in the ISO standard.
