ISO 3455:2007 specifies the procedure of calibration of current-meters of rotating-element type as well as stationary-sensor type (electromagnetic type) in straight open tanks. It also specifies the types of tank, rating carriage and equipment to be used and the method of presenting the results.
The procedure does not take into account any possible difference existing between the behaviour of a current-meter moving in motionless water and that of a fixed current-meter in turbulent flow.

Frequently Asked Questions

An EU Regulation is a binding legislative act that must be applied in its entirety across the European Union. Unlike directives, regulations do not need to be transposed into national law and are directly applicable in all member states. Regulations are used when uniform application across all EU countries is essential.

Regulation TP114-DEMO covers "Uredba o emisiji snovi in toplote pri odvajanju odpadnih voda v vode in javno kanalizacijo". There are 2 standards associated with this regulation.

Harmonized standards under TP114-DEMO are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of TP114-DEMO, facilitating CE marking and free movement within the European Economic Area.
