Standard Current

Centrifugal, mixed flow and axial pumps. Code for hydraulic performance tests. Precision grade.

Forms the first of a set dealing with tests of pumps and specifies precision class tests (former class A). Engineering class I and class II tests (former classes B and C) will be the subject of a further standard. Defines the terms and quantities that are used and specifies general requirements for tests. Does not specify constructional tolerances.

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!
