ASTM D6845-02-Reapproved2008<\/h3>\n

Historical Standard: Standard Test Method for Silica, Precipitated, Hydrated\u2014<\/span>CTAB (Cetyltrimethylammonium Bromide) Surface Area<\/h4>\n
\n

ASTM D6845<\/h4>\n

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

1.1 This test method covers the measurement of the specific surface area of precipitated silicas exclusive of area contained in micropores too small to admit hexadecyltrimethylammonium bromide (cetyltrimethylammonium bromide, commonly referred to as CTAB) molecules. This test method is suitable for characterizing rubber-grade silicas of all types.<\/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
