Crude petroleum and petroleum products. Determination of density. Oscillating U-tube method.

Le présent document concerne les produits pétroliers manipulés habituellement à l'état liquide. Il décrit une méthode de détermination de la masse volumique reposant sur le phénomène de changement de fréquence d'oscillation en fonction du changement de masse et sur un étalonnage à l'air et à l'eau. Des densimètres à tube en U oscillant sont disponibles sur le plan commercial pour réaliser cette détermination.

Loss of light components leads to changes in density during both the sample handling and the density determination.</span></p> <p class="MsoBodyText" style="mso-layout-grid-align: none; text-autospace: none;"><span lang="EN-GB" style="mso-bidi-font-size: 12.0pt; mso-fareast-font-family: 'MS Mincho'; mso-fareast-theme-font: minor-fareast;">This method is not intended for use with in-line density meters.</span></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.

With Requirements, quickly access the main part of the normative text!
