ASTM D7515 - 19

Standard Test Method for Purity of 1,3-Propanediol (Gas Chromatographic Method)

Status : Current   Published : October 2019



1.1 This test method describes the gas chromatographic determination of purity for 1,3-propanediol (PDO). This test method was originally developed to determine the purity of 1,3-propanediol used for the application as the freeze point depressant base fluid in formulated PDO engine coolants. Use of the method for purity of PDO for other applications may be viable.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 Exception—Inch-pound units (psi) are used in Table 1, Pressure Program, Options A and B.

1.3 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
