Rubber - Determination of solvent extract

<p>ISO 1407:2009 specifies three methods for the quantitative determination of the material extractable from raw rubbers, both natural and synthetic, and their unvulcanized and vulcanized compounds.</p> <ul> <li>method A measures the mass of the solvent extract, after evaporation of the solvent, relative to the mass of the original test portion;</li> <li>method B measures the difference in the mass of the test portion before and after extraction;</li> <li>method C, which is for raw rubber only, measures the difference in the mass of the test portion before and after extraction using boiling solvent.</li> </ul> <p>Recommendations as to the solvent most appropriate to each type of rubber are given in an annex.</p>

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.
