Planning reliability Comparison of the product documentation and the actual product delivered reveals that in practice the power consumption of the fan will be lower and the total efficiency level higher than the documented figures.
For higher values, agreement is to be reached between the supplier and the user. Correspondingly, the likelihood of the fan providing the agreed performance, without compromise or concession, is enhanced. A certain amount of tolerance is inevitable with any technical product, for example on account of dimensional deviations in io and assemblies e.
Based on izo size RadiPac fan, analysis shows that ebm-papst attains accuracy class 1 Fig. It is also crucial to ensure that the fan is constructed in such a way that it actually delivers the specified performance level in operation, regardless of the production date.
International Classification for Standards ICS is an international classification system for technical standards. For jet fans refer to ISO It does not apply for fans designed solely for low-volume air circulation, such as those used for household or similar purposes ceiling and table fans, extractor fans, etc.
You can buy this standard from any national standardization 133448. This International Standard specifies performance tolerances and the technical data presentation of industrial fans of all types.
A, free inlet, free outlet; B, free inlet, ducted outlet; C, ducted inlet, free outlet;D, ducted inlet, ducted outlet. The files of this standards is not available in the store right now.
A free inlet, free outlet; B free inlet, ducted outlet; C ducted inlet, free outlet; D ducted inlet, ducted outlet. This quality assurance procedure involves recording all the electrical performance data and confirming compliance with the permissible manufacturing tolerances. The accuracy classes define production-related deviations from fan performance data. Start Webshop Product catalog Product isp. Industrial fans — Tolerances, methods of conversion and technical data presentation.
It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. It is important to us that you purchase the right document.
Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. This ensures that you are always up-to-date and saves you both time and money. Both the fans and the associated documentation are quality products in which planners and operators of air handling units can always place their ieo.
For higher values, agreement is to be reached between the supplier and the user.

Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
Accurate production for correct fan jso At ebm-papst, innovation and quality are at the forefront of our activities.
At the end of the production process, all RadiPac fans are checked in the as-delivered condition for any performance deviations. Follow these links to find other Standards similar to the one you are viewing.
This is the job of a company’s Quality Assurance department. Accordingly the RadiPac product range attains Class 1. DIN — “Fans; Technical delivery conditions” therefore defines accuracy classes and permits deviations from the documented performance characteristics.
Hence there is no risk of any 1348 surprises when the air handling system goes into operation, and there is also no need for any precautionary over-dimensioning of the fan. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
The performance of a fan can vary considerably with the installation category it is operating within.
