Foreword
This Standard modified and adopted the former Soviet Union standard TOCT
6370-1983 (1997) “Petroleum, petroleum products and additives - Method for
determination of mechanical admixtures”.
This Standard was re-drafted in accordance with TOCT 6370-1983 (1997).
This Standard modified TOCT 6370-1983 (1997) so as to make it suitable for
the national conditions of China. The structural differences between this
Standard and TOCT 6370-1983 (1997) are shown in Appendix A; and technical
differences are shown in Appendix B. The main technical differences between
this Standard and TOCT 6370-1983 (1997) are as follows.
- Added “Normative references” in this Standard;
- Made appropriate modifications to “equipment and materials” of TOCT
6370-1983 (1997) in Clause 4 “Equipment and materials”, based on
Chinese actual situation;
- TOCT 6370-1983 (1997) requires to use white or red card quantitative
analysis filter paper, and white card filter paper is required in arbitration
test; this Standard adopts quantitative filter paper of which the speed is
moderate and diameter is 11 cm based on Chinese national conditions
(GB/T 1914);
- Deleted 2.4 and 2.5 of TOCT 6370-1983 (1997), i.e., “ Before filter paper
or porous glass filter reaches to constant weight, it shall use the solvent
used in the test to rinse in advance”; added 7.9 and blank test correction
during calculation;
- Added notes in 7.4; made description of the processing of new porous
glass filter and the cleaning after use;
- Added Appendix A “Comparison on clause number between this Standard
and TOCT 6370-1983 (1997)” and Appendix B “Technical differences
between this Standard and TOCT 6370-1983 (1997)”.
This Standard replaces GB/T 511-1988 “Petroleum products and additives -
Method for determination of mechanical admixtures (gravimetric method)”
which was formulated by adopting TOCT 6370-59 “Petroleum products and
additives - Method for determination of mechanical admixtures”.
Compared with GB/T 511-1988, the main changes are as follows.
- The name of this Standard was modified as “Petroleum, petroleum
products and additives - Method for determination of mechanical
admixtures”;
- The application was modified as. petroleum, liquid petroleum products
and additives; not applicable to lubricating grease and asphalt;
- Modified porous glass filter specifications in this Standard based on TOCT
6370-1983 (1997);
- In reagents, benzene was replaced by toluene, and ethanol-benzene
mixed solvent (1.4) was replaced by ethanol- toluene mixed solvent (1.4);
- For constant weight paper or porous glass filter, the oven temperature
was modified from 105°C~110°C to 105°C±2°C; and the first drying time
was modified from “not less than 1h” to “not less than 45 min”;
- During preparation, this Standard deleted “when using filter paper, when
using ethanol-benzene mixture or ethanol-ether mixture to continue
rinsing in the test instead of distilled water, it shall use 50 mL of above-
mentioned solvents to rinse the filter paper”; added the calculation of blank
test correction in calculation equation;
- Dilution ratio of sampling volume and solvent in this Standard was
modified based on TOCT 6370-1983 (1997);
- Solvent for rinsing in test procedures was modified based on TOCT 6370-
1983 (1997);
- During determination of mechanical admixtures in petroleum, this
Standard added “use silver nitrate solution to inspect chloride in filtrate”;
- Precision was modified according to TOCT 6370-1983 (1997);
requirements for repeatability is stricter; added reproducibility.
Appendix A and Appendix B of this Standard are informative.
This Standard was proposed by National Standardization Technical Committee
on Petroleum Products and Lubricants.
This Standard shall be under the jurisdiction of Petroleum Fuels and Lubricants
Technical Committee of National Standardization Technical Committee on
Petroleum Products and Lubricants.
The drafting organization of this Standard. North-China Institute of China
Petrochemical Sales Co., Ltd.
Drafter of this Standard. Chen Chunhui.
This Standard replaces the following previous standards.
- GB/T 511-1965, GB/T 511-1977, GB/T 511-1988.

quantitative filter paper or porous glass filter to filter the sample.
This Standard is applicable to determination of mechanical admixtures in
petroleum, petroleum products and additives.
This Standard is not applicable to lubricating grease and asphalt.

3 Method summary
Weigh a certain amount of sample; dissolve it in the solvent used; use constant
weight filter paper or porous glass filter to filter; the admixtures left on the filter
paper or porous glass filter is the mechanical admixtures.
4 Apparatus
4.1 Beaker or wide-necked Erlenmeyer flask.
4.2 Weighing bottle.
4.7 Filtering flask.
4.8 Water bath or heating plate.
4.9 Vacuum pump or water pump. ensure the residual pressure is not greater
than 1.33×103 Pa.
4.10 Dryer.
4.11 Oven. can be heated to 105°C±2°C.
4.12 Infrared light bulb.
5 Reagents and materials
5.1 Reagents
5.1.1 95% Ethanol. chemically pure.
5.1.2 Ether. chemically pure.
5.1.3 Toluene. chemically pure.
5.1.6 Silver nitrate. analytically pure; use it to prepare to be 0.1mol/L aqueous
solution.
5.1.7 Water. comply with requirements for Grade 3 water in GB/T 6682.
5.2 Materials
6 Preparation
6.1 Shake the sample in the container (not exceed 3/4 of container volume) for
5min, and make it well mixed. Paraffinic and glutinous petroleum products shall
be heated in advance to 40°C~80°C. Heat lubricant additives to 70°C~80°C.
Then use glass rod to carefully stir for 5min.
6.2 Put filter paper for test in a clean and dry weighing bottle to weigh.
7 Test procedure
7.1 According to the requirements in Table 1, add well-mixed sample into the
beaker and weigh (at least it suits the total volume of the sample after diluting),
and use solvent for heating (solvent oil or toluene) to dilute in proportion.
7.1.1 When determining petroleum, dark petroleum products, lubricant with
additive and mechanical admixtures in additives, it shall use toluene as solvent.
7.3 If the sample contains water, which makes filtering difficult, it shall make
sample solution still for 10min~20min. Then carefully pour the solvent oil (or
toluene) solution of upper sediment in the beaker into funnel or porous glass
filter. Add (5~15) times (according to volume) of ethanol-ether mixed solvent
into the beaker’s precipitate to dilute. Then filter it. It must use ethanol-ether
mixed solvent and thermal solvent oil (or toluene) to rinse thoroughly the beaker
residues to filter paper or porous glass filter.
7.5 After the filtration, for filter paper with precipitate or porous glass filter, it
shall use washing bottle, filled with solvent oil, which does not exceed 40°C, to
clean till there is no sample traces on filter paper or porous glass filter and the
filtered solvent must be completely transparent and colorless.
7.7 After rinsing filter paper with precipitate or porous glass filter, place the filter
paper with precipitate into the corresponding weighing bottles before filtration.
7.8 If the content of mechanical admixtures does not exceed the requirement
range of technical standard of petroleum products or additives, the second
drying and weighing can be omitted.
7.9 During the test, solvent’s blank test correction shall be conducted at the
same time.
8 Calculation
The content of mechanical admixtures in sample w% (mass fraction) is
calculated according to equation (1).
9 Report
9.1 Take the arithmetic mean of two repeated determinations as test result.
