(a)Sulfur.Sulfur content of gasoline and butane must be determined by use of the following methods:
(1) Through December 31, 2015, the sulfur content of gasoline must be determined by ASTM D2622 or by one of the alternative test methods specified in paragraph (a)(3) of this section. Beginning January 1, 2016, the sulfur content of gasoline must be determined by a test method approved under§80.47.
(2) Through December 31, 2015, the sulfur content of butane must be determined by ASTM D6667 or by one of the alternative test methods specified in paragraph (a)(4) of this section.
(3) Through December 31, 2015, any refiner or importer may use ASTM D3120, ASTM D5453, ASTM D6920, or ASTM D7039 for determining the sulfur content of gasoline provided the refiner or importer test result is correlated with the method specified in paragraph (a)(1) of this section:
(4) Beginning January 1, 2016, the sulfur content of butane must be determined by a test method approved under§80.47. Through December 31, 2015, any refiner or importer may determine the sulfur content of butane using ASTM D4468 or ASTM D3246; provided the refiner or importer test result is correlated with the method specified in paragraph (a)(2) of this section.
(b)Olefins.Olefin content must be determined by use of the following methods:
(1) Through December 31, 2015, olefin content must be determined using ASTM D1319. Beginning January 1, 2016, the olefin content of gasoline must be determined by a test method approved under§80.47.
(2) Through December 31, 2015, any refiner or importer may determine olefin content using ASTM D6550 for purposes of meeting any testing requirements involving olefin content, provided that the refiner or importer test result is correlated with the method specified in paragraph (b)(1) of this section on a site-specific basis, in order to achieve an unbiased prediction of the result in volume percent, for the method specified in paragraph (b)(1) of this section.
(c)Reid Vapor Pressure (RVP).(1) Through December 31, 2015, Reid Vapor Pressure must be determined using ASTM D5191, except the following correction equation must be used:
RVP psi = (0.956 * X) ? 0.347
RVP kPa = (0.956 * X) ? 2.39
Where:
X = Total measured vapor pressure, in psi or kPa.
(2) Beginning January 1, 2016, RVP must be determined by a test method approved under§80.47, except as provided in paragraph (c)(2)(i) of this section.
(i) For reporting purposes, the RVP test result computed from§80.47must continue to utilize the RVP correction equation in paragraph (c)(1) of this section.
(ii) [Reserved]
(d)Distillation.Through December 31, 2015, distillation parameters must be determined using ASTM D86. Beginning January 1, 2016, the distillation parameters must be determined by a test method approved under§80.47. (Note: The precision estimates for reproducibility in ASTM D86-12 do not apply; see §80.47(h).)
(e)Benzene.Through December 31, 2015, benzene content must be determined using ASTM D3606, except that instrument parameters shall be adjusted to ensure complete resolution of the benzene, ethanol and methanol peaks because ethanol and methanol may cause interference with ASTM D3606 when present. Beginning January 1, 2016, the benzene content must be determined by a test method approved under§80.47.
(f)(1) Through December 31, 2015, aromatic content must be determined using ASTM D5769, except the sample chilling requirements in section 8 of this standard method are optional. Beginning January 1, 2016, the aromatic content must be determined by a test method approved under§80.47.
(2) [Reserved]
(3) Through December 31, 2015, any refiner or importer may determine aromatics content using ASTM D1319 for the purposes of meeting any test requirement involving aromatic content; provided that the refiner or importer test result is correlated with the method specified in paragraph (f)(1) of this section.
(g)Oxygen and oxygenate content analysis.(1) Through December 31, 2015, oxygen and oxygenate content must be determined using ASTM D5599. Beginning January 1, 2016, oxygen and oxygenate content must be determined by a test method approved under§80.47.
(2) Through December 31, 2015, when oxygenates present are limited to MTBE, ETBE, TAME, DIPE, tertiary-amyl alcohol and C1 to C4 alcohols, any refiner, importer, or oxygenate blender may determine oxygen and oxygen content using ASTM D4815 for purposes of meeting any testing requirement; provided that the refiner or importer test result is correlated with the method specified in paragraph (g)(1) of this section.
