DIESEL FUEL OIL, GRADE NO. 1-D AND NO. 2-D

TESTING REQUIREMENTS, ASTM D-975 (Latest Version)

A. Full Specification Testing (A Series), includes all of the tests listed below (one price for 1-15). Testing shall be performed in accordance with the specified test method(s).

B. Individual tests are any one, or combination, of tests below (individual prices):

ASTM, 1/

NOTES (D975):

(A) To meet special operating conditions, modifications of individual limiting requirements may be agreed upon between purchaser, seller, and manufacturer.

(B) See Sections 6 and 7 for further statements on diesel fuel requirements.

(C) The test methods indicated are the approved referee methods. Other acceptable methods are indicated in 5.1.

(D) Under United States regulations, if Grades No. 1–D S500 or No. 2–D S500 are sold for tax exempt purposes then, at or beyond terminal storage tanks, they are required by 26 CFR Part 48 to contain the dye Solvent Red 164 at a concentration spectrally equivalent to 3.9 lb per thousand barrels of the solid dye standard Solvent Red 26, or the tax must be collected.

(E) Under United States regulations, Grades No.1–D S5000, No. 2–D S5000, and No. 4–D are required by 40 CFR Part 80 to contain a sufficient amount of the dye Solvent Red 164 so its presence is visually apparent. At or beyond terminal storage tanks, they are required by 26 CFR Part 48 to contain the dye Solvent Red 164 at a concentration spectrally equivalent to 3.9 lb per thousand barrels of the solid dye standard Solvent Red 26.

(F) When a cloud point less than −12°C is specified, as can occur during cold months, it is permitted and normal blending practice to combine Grades No. 1 and No. 2 to meet the low temperature requirements. In that case, the minimum flash point shall be 38°C, the minimum viscosity at 40°C shall be 1.7 mm2/s, and the minimum 90 % recovered temperature shall be waived.

(G) Other sulfur limits can apply in selected areas in the United States and in other countries.

(H) These test methods are specified in 40 CFR Part 80.

(I) Where cetane number by Test Method D613 is not available, Test Method D4737 can be used as an approximation. Although biodiesel blends are excluded from the scope of Test Method D4737, the results of Test Method D4737 for up to B5 blends can be used to show compliance with the cetane number requirement of this specification, because Test Method D4737 has been shown to underpredict the cetane number of such blends on average.

(J) Low ambient temperatures as well as engine operation at high altitudes may require the use of fuels with higher cetane ratings.

(K) It is unrealistic to specify low temperature properties that will ensure satisfactory operation at all ambient conditions. In general, cloud point (or wax appearance point) Low Temperature Flow Test, and Cold Filter Plugging Point Test may be used as an estimate of operating temperature limits for Grades No. 1–D S500; No. 2–D S500; and No. 1–D S5000 and No. 2–D S5000 diesel fuel oils. However, satisfactory operation below the cloud point (or wax appearance point) may be achieved depending on equipment design, operating conditions, and the use of flow-improver additives as described in X5.1.2. Appropriate low temperature operability properties should be agreed upon between the fuel supplier and purchaser for the intended use and expected ambient temperatures. Test Methods D4539 and D6371 may be especially useful to estimate vehicle low temperature operability limits when flow improvers are used. Due to fuel delivery system, engine design, and test method differences, low temperature operability tests may not provide the same degree of protection in various vehicle operating classes. Tenth percentile minimum air temperatures for U.S. locations are provided in Appendix X5 as a means of estimating expected regional temperatures. The tenth percentile minimum air temperatures can be used to estimate expected regional target temperatures for use with Test Methods D2500, D4539, and D6371. Refer to X5.1.3 for further general guidance on test application.

(L) The electrical conductivity of the diesel fuel is measured at the time and temperature of the fuel at delivery. The 25 pS/m minimum conductivity requirement applies at all instances of high velocity transfer (7 m/s) but sometimes lower velocities, see 8.1 for detailed requirements) into mobile transport (for example, tanker trucks, rail cars, and barges).

TESTING REQUIREMENTS, EN 590 (Latest Version)

A. Full Specification Testing (A Series), includes all of the tests listed below (one price for 1-17). Testing shall be performed in accordance with the specified test method(s).

B. Individual tests are any one, or combination, of tests below (individual prices):

EN ISO (note a) IP and/or ASTM Equivalent

NOTES (EN 590):

a See also 5.7.1.

b See also 5.7.4.

c See also 5.7.2.

d For the purposes of this European Standard, polycyclic aromatic hydrocarbons are defined as the total aromatic hydrocarbon content less the mono-aromatic hydrocarbon content, both as determined by EN 12916.

e See also 5.7.3.

f See also 5.2.2.

g See also 5.5.2 and Annex A.

h Further investigation into the total contamination test method to improve the precision, particularly in the presence of FAME, is being carried out by CEN.

i FAME shall meet the requirements of EN 14214, see [3].

j For diesel fuel containing FAME above 2 % (V/V) this is an additional requirement.

k For the calculation of the cetane index the 10 %, 50 % and 90 % (V/V) recovery points are also needed.

l The limits for distillation at 250 °C and 350 °C are included for diesel fuel in line with EU Common Customs tariff.

m EN ISO 3924 gives instructions to convert to ISO 3405-equivalent data. See also 5.7.5.
