Doplňujúce informácie
| 1. Scope |
|
1.1 This test method covers the measurement of specific surface area of carbon black exclusive of area contained in micropores too small to admit hexadecyltrimethyl ammonium bromide (cetyltrimethyl ammonium bromide, commonly referred to as CTAB). However, it should be noted that the preferred method for measuring external surface area is STSA (Test Method D 6556). 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. |
