Standard Specification for Propylene Glycol and Dipropylene Glycol

ABSTRACT
This specification covers propylene glycol and dipropylene glycol for use in the preparation of surface coatings. The material properties enumerated, and apparent specific gravity shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers propylene glycol and dipropylene glycol for use in the preparation of surface coatings.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
1.4 For specific hazard information and guidance, see the supplier's Material Safety Data Sheets.
