This standard is identical to the international standard ISO 8618:1987 Plastics - Liquid phenolic resins - Conventional determination of non-volatile matter.
1 Subject content and application scope
This standard specifies a method for the conventional determination of the non-volatile matter of liquid phenolic resins (resols, novolak solutions, etc.). It can be used for commercial products or for resins in their various stages of manufacture.
Note: For phenolic resins, the term "non-volatile matter" is based upon arbitrary test conditions (see 4.2, note ①). Results obtained by this method may not agree with the results obtained in industrial applications of these resins.
2 Definition
For the purposes of this standard, the following definition is applicable.
non-volatile matter: the percentage residue obtained when the volatile components of a specific mass of a liquid phenolic resin are evaporated under specified conditions of temperature and time
3 Apparatus
3.1 Small disposable dishes made of aluminium, nickel, stainless steel, tinplate or galvanized sheet metal, with a flat base, an inner diameter at the base of 75mm and a height of approximately 25mm.
Note: Dishes of different diameters may be used if the mass of the test portion m1, in grams, is calculated according to the following relation:
