ASTM E28-99-Reapproved2009<\/h3>\n

Historical Standard: Standard Test Methods for Softening Point of Resins Derived from Naval Stores by Ring-and-Ball Apparatus<\/h4>\n
\n

ASTM E28<\/h4>\n

Scope<\/strong><\/p>\n

1.1 These test methods are intended for determining the softening point of resins (including rosin and terpene resins) and similar materials by means of the ring-and-ball apparatus.<\/p>\n

Note<\/span> 1\u2014For testing asphalts, tars, and pitches, see Test Method D 36.<\/p>\n

1.1.1 Test method using the manual ring and ball softening point apparatus, and<\/p>\n

1.1.2 Test method using an automated ring and ball softening point apparatus.<\/p>\n

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.<\/p>\n

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
