Description

ASTM D156-07a

Historical Standard: Standard Test Method for Saybolt Color of Petroleum Products (Saybolt Chromometer Method)

ASTM D156

Scope

1.1 This test method covers the determination of the color of refined oils such as undyed motor and aviation gasoline, jet propulsion fuels, naphthas and kerosine, and, in addition, petroleum waxes and pharmaceutical white oils.

Note 1—For determining the color of petroleum products darker than Saybolt Color − 16, see Test Method D 1500.

1.2 This test method reports results specific to this test method and recorded as, “Saybolt Color units.”

1.3 The values stated in inch-pound units or in SI units and which are not in parentheses are to be regarded as the standard. The values given in parentheses are for information only.

Note 2—Oil tubes and apparatus used in this test method have traditionally been marked in inches, (the tube is required to be etched with ¹/₈ in. divisions.) The Saybolt Color Numbers are aligned with inch, ½ in., ¼ in., and ¹/₈ in. changes in the depth of oil. These fractional inch changes do not readily correspond to SI equivalents and in view of the preponderance of apparatus already in use and marked in inches, the inch/pound unit is regarded as the standard. However the test method does use SI units of length when the length is not directly related to divisions on the oil tube and Saybolt Color Numbers. The test method uses SI units for temperature.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.^
