<p>This International Standard specifies four methods for the determination of the specific surface area of types</p>
<p>and grades of carbon black for use in the rubber industry:</p>
<p>— method A using the Ni‑Count‑1 apparatus (Clause 3);</p>
<p>— method B using the Areameter apparatus (Clause 4);</p>
<p>— method C using gas chromatography (Clause 5);</p>
<p>— method D using the Monosorb surface-area analyser (Clause 6).</p>
<p>Somewhat different results might be obtained from the four methods. The degassing procedure used differs</p>
<p>from method to method, and it is important to investigate the possibility of correcting the results by using</p>
<p>standard reference blacks.</p>
<p>The results might also differ from those obtained using the multipoint method specified in ISO 18852, which is</p>
<p>the preferred method.</p>
