Foreword
Clauses 4, 6 and 8 of this standard are mandatory and the rest are
recommended.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB 252-2011 “General diesel fuels”. As compared with
GB 252-2011, the main changes of this standard are as follows.
- ADD clause 4.1 additives used in general diesel fuel shall have no known

3 Product categories
General diesel fuel is divided into six grades in accordance with the freezing
point.
4 Technical requirements and test methods
4.1 The additives used in general diesel oil shall have no known harmful effects
and shall be used in accordance with the recommended appropriate dosage.
4.2 The technical requirements for general diesel fuel are shown in Table 1.
5 Sampling
Sampling is carried out in accordance with GB/T 4756, taking 4 L for inspection
and sample retention.
6 Marking, packaging, transportation and storage
6.1 The equipment used for general diesel fuel that meets the requirements of
Table 1 sold to the user shall clearly indicate the grade and name of the product.
Example. No.0 general diesel fuel.
7 Safety
In accordance with GB 13690, general diesel oil is a flammable liquid. For the
danger description and precautionary statements, see Appendix D of GB
30000.7-2013.
8 Implementation of standard
This standard shall be implemented as of the date of promulgation and shall be
subject to the gradual introduction of the transition period requirements. For the
requirement for sulfur content in Table 1 being not more than 50 mg/kg, the
transition period is by June 30, 2017, the requirements that the sulfur content
being not more than 350 mg/kg in Table 1 is discarded from July 1, 2017;
Appendix A
(Informative)
Minimum temperature with a risk ratio of 10% in each region
The minimum temperature with a risk ratio of 10% in each region (see Table
A.1) was extracted and compiled from the Temperature Data for Petroleum
Products Standards which was prepared by the Central Meteorological
Administration's Reference Office. The minimum temperature with a monthly
risk ratio of 10% indicates that the probability that the minimum temperature in
the month is lower than this value is 0.1, or otherwise the probability that the
minimum temperature in the month is higher than this value is 0.9.
Appendix B
(Normative)
Inspection of nitrate ester type cetane number improver in diesel
B.1 Scope
B.1.1 This method is applicable to the testing of nitrate ester type cetane
number improvers used in diesel fuel. The method can be used as a qualitative
screening method for determining residual carbon and calculating the cetane
index.
B.1.2 This method involves certain hazardous substances, operations and
equipment and is not intended to advise on all safety issues involved. Therefore,
appropriate safety and protective measures shall be established prior to the use
of this method and the applicability of the relevant regulatory restrictions shall
be determined.
B.2 Method summary
The diesel specimen is saponified in a potassium hydroxide-n-butanol mixture,
filtered by a glass fiber filter paper, the material remaining on the filter paper is
dried and treated with a diphenylamine reagent. Diphenylamine is oxidized by
nitrate to a deep blue quinoid compound. The resulting blue or blue-black spots
indicate that there is a nitrate type cetane number improver. No color change
indicates that there is no nitrate type cetane number improver.
B.3 Instruments or equipment
B.3.1 Reaction bottle. A 30 mL wide mouth jar with a thread cap, there is a tin
or plastic lining inside the cap.
B.5 Test procedure
B.5.1 MIX 6.5 g of potassium hydroxide with 100 mL of n-butanol, HEAT to
dissolve potassium hydroxide, after the solution is cooled, USE the glass fiber
filter paper to filter the mixture, to obtain a saponified mixture.
B.5.2 PIPETTE 10 mL of the specimen into the reaction flask, ADD 5 mL of
toluene, ADD 10 mL of the saponified mixture.
Warning. Pipettes shall not be inhaled by mouth because of the presence
of toxic substances in the test.
B.5.3 USE a thread cap to firmly cover the reaction bottle, MIX the contents,
PLACE it in an oven at 110 °C for 4 h.
B.5.4 REMOVE the reaction bottle from the oven, COOL it to 25 °C ± 3 °C.
B.5.5 FILTER the contents of the reaction bottle in a glass sintered filter
equipped with glass fiber filter paper.
B.5.6 USE 2.5 mL of toluene to rinse the reaction bottle, TRANSFER it into the
glass sintered filter for filtration.
B.5.7 Carefully REMOVE the glass fiber filter paper, PLACE it into an oven at
110 °C to dry it for 15 min.
B.5.8 REMOVE the glass fiber filter paper, COOL it to 25 °C ± 3 °C.
B.5.9 ADD 3 drops of diphenylamine solution to the center of the filter paper,
OBSERVE if blue or blue-black color is formed.
