Scope
1.1 The test methods specified in this part of GB/T 12008 are used to determine the acidic components in polyether polyols, and the results are expressed in terms of acid value. The typical acid value (calculated by the amount of KOH consumed) ranges from 0 to 0.1 mg/g.
1.2 This part does not address any safety issues related to use. Before use, it is the user's responsibility to establish appropriate safety and health measures and determine the scope of applicable management restrictions.
