This Standard is applicable to determine the silicon content of 1.0mg/kg ~ 50.0mg/kg in the motor gasoline (the volume fraction of oxygen-containing compounds shall not exceed 15%), such as motor gasoline containing methyl tert-butyl ether, motor methanol gasoline (M15) and motor ethanol gasoline (E10). For the motor gasoline sample with silicon content higher than 50.0mg/kg, it can be diluted by the isooctane with higher proportion, then determine according to this Standard method; but its precision has not been statistics yet. When testing according to this Standard, some elements in the motor gasoline like sulfur, lead, iron, manganese, phosphorus and chlorine shall not interfere the determination results of the silicon content. Basic Data Standard ID GB/T 33647-2017 (GB/T33647-2017) Description (Translated English) Determination of Silicon Content in Motor Gasoline - Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) Sector / Industry National Standard (Recommended) Classification of Chinese Standard E30 Classification of International Standard 75.160.20 Word Count Estimation 9,956 Date of Issue 2017-05-12 Date of Implementation 2017-12-01 Quoted Standard GB/T 4756; GB/T 17476 Issuing agency(ies) General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary This standard specifies a test method for the determination of silicon content in automotive gasoline using an inductively coupled plasma emission spectrometer (ICP-OES). This standard applies to the determination of silica content of 1.0 mg/kg ~ 50.0 mg/kg of vehicle gasoline (oxygen content of the volume fraction of not more than 15%), such as methyl tert-butyl ether vehicle gasoline, vehicle methanol gasoline (M15) and vehicle ethanol gasoline (E10). For automotive gasoline samples with a silicon content above 50.0 mg/kg can be diluted by a higher proportion of isooctane and determined according to this standard method, but its precision is not yet counted. When used in this standard, certain elements such as sulfur, lead, iron, manganese, phosphorus and chlorine in vehicle gasoline do not interfere with the results of silicon measurement.
