Foreword

Clauses 4 and 5 of this Standard are compulsory; the others are voluntary. This Standard was drafted in accordance with the rules given in GB/T 1.1-2009. This Standard replaces GB 1787-2008, Aviation piston engine fuels. Compared with GB 1787-2008, the major changes of this Standard are as follows: -- it adds two designations, No. UL91 and No. 100LL, and all indexes (see Table 1); -- for determination of lead content, it adds test method and reference ASTM D5059, Standard test methods for lead in gasoline by X-ray spectroscopy and list it as arbitration method (see Table 1); -- it adds test method for colour and reference ASTM D2392, Standard test method for color of dyed aviation gasolines, and requirements for dyestuff and quantity added (see Table 1); -- for determination of density, it adds test method and reference SH/T 0604, Crude petroleum and petroleum products - Determination of density - Oscillating U-tube method, and lists it as arbitration method (see Table 1); -- for determination of sulfur content, it adds test method and reference NB/SH/T 0842, Standard test method for sulfur in gasoline and diesel fuel by monochromatic wavelength dispersive X-ray fluorescence spectrometry, and changes arbitration method from GB/T 380, Determination of sulfur content in petroleum products (lamp method), into SH/T 0689, Standard test method for determination of total sulfur in light hydrocarbons motor fuels and oils by ultraviolet fluorescence (see Table 1); -- it cancels iodine value and existent gum items; -- it only has requirements for numbers 75 and 95 in respect of acidity and aromatic hydrocarbon indexes. This Standard was proposed by and shall be under the jurisdiction of the National Energy Administration. The drafting organizations of this Standard. Sinopec Research Institute of Petroleum Processing, CNPC Lanzhou Petrochemical Branch, Sinopec Beijing Yanshan Branch. The main drafters of this Standard. Gong Dongmei, Tao Zhiping, Zhang Cuijun, Ling Liexiang, Cheng Ye, Liu Hua. The previous editions of the standard replaced by this Standard are as follows: Aviation piston engine fuels Warning - This standard may involve certain hazards in the process of production, transportation, loading, use, etc. of the products covered by it, if appropriate protective measures are not taken, but it does not purport to address all of the safety concerns, if any. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1 Scope

GB 1787-2018 is the Chinese national standard on aviation piston engine fuels, in the field of petroleum and related technologies. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 13 July 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 February 2019. Classification: ICS 75.160.20, CCS E31. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard specifies the classification and designation, requirements and test methods, inspection rules, marking, packaging, transportation and storage and safety of aviation piston engine fuels, which are produced using the materials and processes approved through the national evaluation procedure and adding appropriate additives. This Standard applies to aviation piston engine fuels.

3 Classification and designation

3.1 Classification Aviation piston engine fuels includes 5 designations according to motor octane numbers, including numbers 75, UL91, 95, 100 and 100LL, with "UL" representing unleaded and "LL" representing low lead.

3.2 Designation Aviation piston engine fuels complying with the technical requirements of Table 1 of this Standard shall be designated as "No. 75 aviation piston engine fuel", "No. UL91 unleaded aviation piston engine fuel", "No. 95 aviation piston engine fuel", "No. 100 aviation piston engine fuel" or "No. 100LL low lead aviation piston engine fuel". The inspection of this product is exit-factory inspection. The items of exit-factory inspection include all inspection items specified in the technical requirements of Clause 4 (all the items in Table 1).

5.2 Batch On the condition that the materials and processes remain unchanged, each tank of the product produced is a batch.

5.3 Sampling Carry out sampling as specified in GB/T 4756. Take 4 L of oil sample for each batch of no. 75 and 91 for inspection and 1 L as reserved sample; take 10 L of oil sample for each batch of no. 95, 100 and 100LL for inspection and 2 L as reserved sample.

5.4 Criteria The product can be delivered only when all exit-factory inspection results pass.

5.5 Re-inspection rules If there is any item in the exit-factory inspection fails to meet the requirements of Table 1, then take a double amount of sample to carry out re-inspection as specified in GB/T 4756. If there still one items in the re-inspection results failing to meet the requirements of Table 1, then the batch of product is rejected.

6 Marking, packaging, transportation and storage

According to GB 30000.7-2013, aviation piston engine fuels are flammable. Therefore, their marking, packaging, transportation and storage and delivery acceptance shall be as specified in SH 0164, GB 13690 and GB 190.
