Alternative test methods and technology for several of the methods can be found in the Appendix. The alternative test methods do not have precision data for the application of these methods in analyzing glycols. Use of these methods is optional and individuals using the alternative methods should assure themselves that the method is sufficiently precise. Precision data presented is only for the original test methods listed.1.1 These test methods cover the chemical and physical analysis of the commonly available grades of ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, and dipropylene glycol. The key sections appear in the following order: SectionsPurity of Reagents Specific GravityDistillation Range Acidity Water IronColor Gas Chromatographic Analysis 1.2 Review the current appropriate Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
