ASTM D1614-95(1999)

Standard Test Method for Alkalinity in Acetone

SCOPE
1.1 This test method covers the determination in acetone of alkalinity calculated as ammonia (NH 3 ).  
1.2 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.
1.3 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet.
