Historical Standard: ASTM C374-70(2004)e1 Standard Test Methods for Fusion Flow of Porcelain Enamel Frits (Flow-Button Methods)
SUPERSEDED (see Active link, below)
ASTM C374
1. Scope
1.1 These test methods cover evaluation of the relative fusion flow characteristics of samples of a given porcelain enamel frit by comparison with an established standard for that frit.
1.2 Two methods are included, differing only in certain details of the samples and in the apparatus and procedure for preparation of test specimens. Both methods give equally reproducible results and provide a satisfactory basis for comparison of fusion flow of the sample with that of the established standard.
1.2.1 Method A employs granular particles of frit to which a bonding agent has been added. Button specimens are formed under high pressure in a hydraulic press.
1.2.2 Method B employs crushed, sized particles of frit to which a bonding agent has been added. Button specimens are formed in a steel mold by hand.
