ASTM D1218-02-Reapproved2007<\/h3>\n

Historical Standard: Standard Test Method for Refractive Index and Refractive Dispersion of Hydrocarbon Liquids<\/h4>\n
\n

ASTM D1218<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the measurement of refractive index, accurate to four decimal places or better, of transparent and light-colored hydrocarbons in the range of 1.3300 to 1.5000 at temperatures from 20 to 30\u00b0<\/span>C by manual (optical-mechanical) or automatic (digital) procedure.<\/p>\n

1.2 The manual (optical-mechanical) procedure also covers the measurement of refractive dispersion accurate to the fourth decimal place or better.<\/p>\n

Note<\/span> 1\u2014The test method may be suitable for measuring the refractive indices of liquids above 1.5000 and at temperatures both below 20\u00b0<\/span>C and above 30\u00b0<\/span>C; however, the test method precision may not apply. Verification of the accuracy of such measurements will depend upon the availability of reliable, certified reference standards that demonstrate the performance of the instrument used under the particular measuring conditions.<\/p>\n

1.3 The test method may not be applicable to liquids that are strongly colored, or that have bubble points so near the test temperature that a reading cannot be obtained before substantial weathering takes place. Liquid color should be limited to No. 4 ASTM Color or lighter, as determined by Test Method D 1500.<\/p>\n

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.<\/span><\/p>\n
