Significance and Use
These test methods can be used to characterize the odors of ethylene, diethylene, triethylene, propylene, and dipropylene glycol and estimating the intensity of the odor. The products are compared to previously established standards. The acceptability of the product for a specific end use can be determined with this information.
A procedure which can be used to characterize the taste of propylene glycol and establish the intensity of this taste relative to a previously established standard is delineated. The acceptability of the product for a specific end use can be determined with this information.
These tests may be used to qualify the suitability of these products for use in a customer-producer relationship.
Scope
1.1 These test methods cover procedures for observing odors of glycols and estimating their odor acceptability. These test methods apply to ethylene, diethylene, triethylene, propylene, and dipropylene glycols. A method for observing the taste and estimating the intensity of the taste of propylene glycol is also included.
1.2 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.
