Fans - Performance testing using standardized airways

ISO 5801:2017 specifies procedures for the determination of the performance of fans of all types except those designed solely for air circulation, e.g. ceiling fans and table fans. Testing of jet fans is described in ISO 13350.ISO 5801:2017 provides estimates of uncertainty of measurement and rules for the conversion, within specified limits, of test results for changes in speed, gas handled and, in the case of model tests, size are given.

Industrial fans - Performance testing using standardized airways

Le présent document traite de la détermination des performances des ventilateurs industriels, à l'exception de ceux destinés à la circulation de l'air. Il donne quatre méthodes de calcul des performances pour quatre catégories d'installation permettant l'utilisation des installations d'essais déjà existantes.

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.
