'''3.1'''<br>
biodiesel<br>
blendstock for middle distillate fuels comprised of mono-alkyl esters of long chain fatty acids derived from renewable sources. In its neat form, biodiesel is commonly designated as B100 or fatty acid alkyl esters with fatty acid methyl esters (FAME) being the most common (see 6.25).
'''3.x'''<br>
conventional hydrocarbons<br>
petroleum-derived hydrocarbons from natural gas liquid condensates, crude oil, heavy oil, shale oil and oil sands, which are generally accompanied by lower levels of naturally occurring non-hydrocarbons.<br>
'''3.2'''<br>
operability temperature<br>
lowest temperature at which the fuel oil is designed to provide satisfactory performance under the conditions of storage and use (see 6.23, 6.24 and 9.2).The 2.5 percentile low-end design temperature is the temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.<br>
'''3.3'''<br>
synthetic hydrocarbons<br>
hydrocarbons derived from non-petroleum sources such as biomass, natural gas, coal, fats and oils by processes such as gasification, reforming, Fischer-Tropsch synthesis, hydroprocessing or hydrocracking (including co-processing with petroleum).<br>
'''3.y'''<br>
2.5 percentile low-end design temperature <br>
temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.<br>
<h1> Classification </h1>
'''4.1 '''
Heating fuel oils shall be supplied in the following types, as specified (see 8.1):
4.1.1 Types
Type 0<br>
Type 1<br>
Type 2<br>
Type 4<br>
Type 5<br>
Type 6<br>
<h1> General requirements </h1>
'''5.1 '''Unless otherwise allowed (see 5.4 and 6.17), the heating fuel oils shall consist of conventional hydrocarbons (i.e. petroleum-derived from natural gas liquid condensates, crude oil, heavy oil, shale oil and oil sands), synthetic hydrocarbons (see 9.13) or mixtures of conventional and synthetic hydrocarbons and may include naturally occurring non-hydrocarbons. <br>
'''5.2 '''The heating fuel oils may contain additives designed to improve the characteristics or performance of the fuel oil. Additives include those that enhance low-temperature flow properties, storage life, static charge dissipation, water haze dissipation, lubricity and inhibit corrosion.<br>
'''5.3 '''The heating fuel oils shall be a stable homogeneous liquid, free of foreign matter that is likely to clog filters or nozzles, or to damage equipment.<br>
'''5.4 '''In Types 0, 1 and 2 fuel oils, there shall be no intentional addition of used lubricating oils, used solvents, triglycerides (such as raw vegetable oils, animal fats, fish oils or used cooking oils), or other fluids which are not normal components of the fuel. Types 4, 5 and 6 fuel oils may contain used lubricating oils or other fluids provided that the fuel oil is used in specifically designed equipment and the relevant authority approves their use.<br>
'''5.5 '''The heating fuel oils shall remain undyed except when it is required for taxation purposes by provincial or territorial regulation.<br>
<h1> Detailed requirements </h1>
<h2> Specified limiting values </h2>
'''6.1.1''' The heating fuel oil shall comply with the specified limiting values. The specified limiting values shall not be changed. This precludes any allowances for the test method precision and for adding or subtracting digits.<br>
'''6.1.2''' For purposes of determining conformance with the specified limiting values, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specified limiting value, in accordance with the rounding-off method of ASTM E29. There are two exceptions (see 6.3 and 6.17).<br>
'''6.1.3''' If an alternate test method referenced in this standard provides a bias correction to the referee method, adherence to the specified limiting value shall be based on the bias-corrected result.<br>
'''6.1.4''' Where test values differ between two parties, a resolution shall be in accordance with ASTM D3244 in order to determine conformance with the specified limiting values, with the criticality of the limits set at P = 0.5.<br>
'''6.1.5'''Zeroes trailing the last nonzero digit for numbers represented with a decimal point are significant digits, in accordance with ASTM E29.
<h2> Test methods </h2>
'''6.2.1''' Test methods other than those referenced in this standard may be used only if they have been validated in accordance with ASTM D3764 or D6708.<br>
'''6.2.2''' Validated test methods shall correlate with methods referenced in the standard. Differences in precision, sensitivity and bias between methods referenced in the standard and the validated methods shall be noted when using results from validated methods.<br>
'''6.2.3''' Validated test methods shall only be used within the bounds of the data covered in their validation.<br>
'''6.2.4''' In the event of a dispute, the procedures given in 6.1 shall be used.<br>
'''6.2.5''' If parties in a dispute cannot agree on an analytical method to resolve the dispute, the referee method listed in the standard shall be used.<br>
