Liquid pumps and installation - General terms, definitions, quantities, letter symbols and units - Part 1 : liquid pumps

<p>ISO 17769-1:2012 specifies terms, letter symbols and units related to the flow of liquids through rotodynamic and positive displacement liquid pumps and associated installations. It serves as a means of clarifying communications between the installation designer, manufacturer, operator and plant constructor. It identifies the units in common usage, but all additional legal units can be used.</p> <p>ISO 17769-1:2012 deals solely with conditions described by positive values for the rate of flow and pump head. </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!
