Foreword
This standard replaces GB/T 7607-2002 "diesel oil oil change indicator."
Compared with the standard GB/T 7607-2002 The main changes are as follows.
--- Increasing the GB/T 261, SH/T 0688, GB/T 17476 and ASTMD6595 as closing point (closed), base value and iron content
Detection methods (see Chapter 2);
--- Remove the GB/T 3536, SH/T 0197 (see Chapter 2);
--- Increasing the diesel engine oil CF-4, CH-4 diesel engine oil oil change indicator, remove SD/CC, SE/CC two Universal Oil Products Oil Change
Indicators; increasing the flash point, the copper content, aluminum content, silicon content test items; deleted opening flash point test items (see 3.1);
--- Increasing the base value decrease rate formula (see 3.3);
--- Control the acid value added index revised to 2.5mg/g (in dollars KOH), n-pentane insolubles control index revised to 2.0% (see 3.1);
--- Delete the original standard in Appendix A (see 2002 edition).
Appendix A of this standard is an informative annex.
This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed.
This standard by the National Petroleum Products and Lubricants Standardization Technical Committee lubricating oil change indicator Technical Committee (SAC/TC280 /
SC6) centralized.
This standard drafting units. China Petroleum & Chemical Corporation lubricants R & D (Shanghai) Center, China National Petroleum shares have
Limited Dalian lubricant research and development centers.
The main drafters of this standard. Wang Yaping, She Haibo, Wang Shaochun, painted Jinsong.
This standard replaces the standards previously issued as follows.
GB/T 7607-1987, GB/T 7607-1995, GB/T 7607-2002.
Diesel oil oil change indicator
1 Scope
This standard specifies the use of diesel oil during the oil change indicator.
This standard applies to CC, CD, SF/CD, CF-4, CH-4 diesel engine oil quality level in diesel vehicles, stationary diesel engines and boats
Diesel (not including the use of heavy fuel oil for diesel engines) to use in the process of quality control.

3 requirements and test methods
Technical Requirements 3.1 diesel engine oil oil change indicator and test methods are shown in Table 1, when the oil has reached an indicator of when the oil change indicator
Replaced with new oil.
Viscosity change rate of 3.2 movement by the formula (1).
η1 =
ν2-ν1

100 (1)
Where.
η1 --- viscosity change rate movement,%;
New oil kinematic viscosity ν1 --- Found in square millimeters per second (mm2/s);
ν2 --- use oil kinematic viscosity measured value, units per square millimeter (mm2/s).
3.3 TBN decrease rate according to equation (2).
η2 =
X1-X2
