- Scope
- This standard specifies the gravimetric method for determining the amount of extractables from ground phenolic molded product samples using acetone near its boiling point. The acetone soluble test is a method for determining the relative curing degree of phenolic molded products made of phenolic molding compound. The extraction process should be carried out within the specified time under the specified conditions. Although most of the soluble matter is determined, the extraction is not necessarily complete, and the result is only a comparative result, because the extract often contains substances other than the uncured resin (such as lubricants, colorants and plasticizers). ).
