Foreword
This revised standard adopts ISO 15167.1999 "Petroleum products --- middle distillate fuels - Determination of Particulate Matter (Laboratory Filtration
Law) "(in English).
This standard is based on ISO 15167.1999 redrafted.
In order for China's national conditions, the use of this standard in the ISO 15167.1999 when modified. This standard and ISO 15167.1999 is
The main differences are as follows.
--- References of standards adopted corresponding national standards;
--- Repeatability and reproducibility statements by our habit of rewriting the text;
--- Delete Chapter 14 test report.
This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) and focal points.
This standard was drafted. China Sinopec Group Luoyang Petrochemical Engineering Corporation Engineering Institute.

This standard is the first release.
Determination of middle distillate fuel particulate matter content
Laboratory Filtration
Warning. This standard may involve some hazardous materials, operations and equipment, but not for all of the safety issues involved in the use of all proposed
Suggest. Therefore, before using this standard, the user has the responsibility to establish appropriate safety and health practices and determine the appropriate management system.
1 Scope
Intermediate 1.1 standard for the determination of flash point of not less than 38 ℃ (using GB/T 261 Determination) fraction of particulate matter content of the fuel, not
Determination of suitable light distillate fuels (such as gasoline) or jet fuel.
1.2 pairs for diesel engines and particulate matter content limit civilian middle distillate fuels, prevents clogging of the filter and other operations
As a problem. The standard measurement range of not more than 25g/m3.
1.3 only in strict accordance with the terms of this standard is measured, in particular membrane material (see note 6.9), the amount of the sample and the sample are in line with full filtration
This standard specifies, the precision of this standard is valid.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Under this standard test conditions, trapped in a nominal pore size of 0.8μm membrane on the amount of substance in g/m
3 shows.
4. Summary
Samples with a volume of premeasured test membrane filtration, after rinsing and drying to obtain quality Weigh incremental test membrane, while
Incremental test quality can be obtained membrane located below the control membrane. With incremental quality control test membrane minus the mass increase membrane
To obtain particles content in the sample.
5 Reagents and materials
Unless otherwise stated, all tests are used during the analytical reagents. Water should be consistent with GB/T 6682 in tertiary water requirements.
5.1 Isopropanol. chemically pure, before using a pore size of 0.45μm or smaller pore size membrane filter.
5.2 liquid detergent. water-soluble.
5.3 Rinse solution. n-heptane, or 2,2,4-trimethylpentane. Before using a pore diameter of 0.45μm or smaller pore size filter membrane.
5.4 Water. Clean, drinkable standards. If no suitable water filter in accordance with 5.3 to get the right water or using a commercially available pure
Water instead.
