Rubber compounding ingredients - Carbon black - Determination of specific surface area by nitrogen adsorption methods - Single-point procedures

This document specifies two methods for the determination of the specific surface area of types and grades of carbon black for use in the rubber industry:— method A: automatic gas chromatography method (carrier gas method);— method B: automatic volumetric method.Somewhat different results might be obtained from the two methods. The degassing procedure differs between method A and method B, and it is important to investigate the possibility of correcting the results by using standard reference blacks.The results might also differ from those obtained using the multipoint method specified in ISO 18852, which is the preferred method.These methods are not applicable to porous carbon blacks.

Rubber compounding ingredients - Carbon black - Determination of specific surface area by nitrogen adsorption methods - Single-point procedures

This document specifies two methods for the determination of the specific surface area of types and grades of carbon black for use in the rubber industry:

— method A: automatic gas chromatography method (carrier gas method);

— method B: automatic volumetric method.

Somewhat different results might be obtained from the two methods. The degassing procedure differs between method A and method B, and it is important to investigate the possibility of correcting the results by using standard reference blacks.

The results might also differ from those obtained using the multipoint method specified in ISO 18852, which is the preferred method.

These methods are not applicable to porous carbon blacks.

Rubber compounding ingredients - Carbon black - Determination of specific surface area by nitrogen adsorption methods - Single-point procedures

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

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
