Foreword
No.1~No.6 fuel oil in this Standard are formulated by equivalently adopting ASTM D396-93 ?€?Standard specification for fuel oils?€?. Based on the current practical situation, it adds the high-viscosity No.7 fuel oil. The writing format of the standard is in accordance with GB/T 1.1-1993; test methods adopt, as possible, the Chinese national standards or industry standards which are the same as or corresponding to the methods of ASTM standard.
This Standard replaces the SH 0356-92, since the date of implementation. This Standard was proposed by and shall be under the jurisdiction of Sinopec Petrochemical Science Research Institute.
Responsible drafting organization of this Standard. Sinopec Petrochemical Science Research Institute.
Main drafter of this Standard. Lu Qiping.
Fuel oil
1??Scope
This Standard specifies the technical conditions of eight kinds of fuel oils used in different operating conditions and in different burners.
This Standard can be used for specification of fuel oils in supply-purchase contract. It can also be used as the guide when the fuel oil users select the most suitable grade-numbers they need.

3??Grade?€?numbers
Fuel oil can be divided into eight grade-numbers. No.1, No.2, No.4-light, No.4, No.5-light, No.5-heavy, No.6, and No.7.
No.1 and No.2 are distillate fuel oil that apply to home-use or industrial small burner. Especially, the No.1 applies to pneumatic type burner, or it can be used at the occasion that the low pour point fuel oil is required in the storage conditions. No.4-light and No.4 are heavy distillate fuel oil, or the fuel oil that is combined by distillate fuel oil and residual fuel oil. They apply to the industrial burners which require this viscosity range.
No.5-light, No.5-heavy, No.6, and No.7 are the residual fuel oil of which the viscosity and distillation range are incremental. They apply to industrial burners. In order to load-unload and atomize normally, the fuel oil usually needs to be preheated. 4??Technical??contents
4.1 General requirements

Pour point, C4) Not more than -18 -6 -6 -6 - - 5) - GB/T 3535
Note.
1 If there is one index of certain grade-number of fuel oil in this Standard not complying, it still can not be automatically changed to the next grade-number, unless it complies with all the requirements of the next grade-number. However, for modification of individual indicators of special operating conditions, it can be negotiated among buyer, seller and manufacturing plant.
2 Test methods can also adopt the corresponding methods listed in Chapter 2. However, the test method specified in Table 1 is the arbitration method.
1) The total value OF water that is determined by using the distillation method in GB/T 260 AND precipitates that are determined by using extraction method in GB/T 6531 shall not be more than the value shown in the table. The precipitates obtained by extraction method in No.6 fuel oil must not be more than 0.50% (m/m). When the water and precipitates are more than 1% (v/v), the value shall be all deducted from the total value. When the water and precipitates of No.7 fuel oil are more than 2% (v/v), the value shall be all deducted from the total value. If there is dispute, the measuring results in GB/T 6533 shall prevail.
2) If low-sulfur fuel oil is needed, the light-viscosity fuel oil can be supplied in accordance with the negotiation between the supplier and purchaser.
3) The limit value is to guarantee the lowest heat value, and to avoid misinformation as No.2 fuel oil and incorrect use.
4) As long as it is needed by storage and use, the pour point can be specified to be lower and higher. However, when the pour point is lower than -18??C, the viscosity of No.2 fuel oil shall not be less than 1.7 mm2/s. At the same time, it shall not control the 90% of recovery temperature. 5) If the low-sulfur fuel oil is needed, No.6 fuel oil shall be divided into grades of low pour point (not more than +15??C) or high pour point (do not control the maximum value); if the oil tank and pipeline are without heating facilities, it shall use the low-pour-point fuel oil.
5??Marks,??packaging,??transportation,??and??storage
Marks, packaging, transportation, storage, and delivery acceptance shall be conducted in accordance with SH 0164.
6??Sampling
Sampling shall be in accordance with GB/T 4756; take 2L of fuel oil for inspection and reserving-sample.
