European Standard EN 12380:2002
The first European standard (EN 12380:2002) to cover the requirements, test methods and evaluation of conformity for Air Admittance Valves (AAVs) for drainage systems installed within buildings (in accordance with European Standard EN 12056-2:2002) was published in December 2002. Having been instrumental in its development, Studor fully embraced the introduction of the standard, which sets the performance requirements for AAVs and how the manufacturer should demonstrate compliance with the standard.
Contained within EN 12380:2002 is a table (see below) which classifies AAVs based on their performance – AI is the highest classification and BIII is the lowest classification.

flood level of connected appliances
The Studor AAVs are AI classified, which means that they may be installed in extreme temperatures and below the flood level of the appliance.
The Studor combined traps and AAVs are AII classified, which means that they may be installed in temperatures ranging from 0°C to +60°C and below the flood level of the appliance.
There are a number of AAVs on the market with varying performances. This classification is essential to differentiate between them.
The CE mark
The CE mark applied to a product is a self-certification by the manufacturer that the product fulfils the essential requirements of the relevant European standard. In most cases there is no requirement for independent validation of certification, which puts an element of trust on the manufacturer to make a truthful declaration.
Studor has sought independent validation for their core products to verify the right to apply the CE mark and prove conformance to EN 12380:2002. These products are tested every two years by an independent testing institute and Studor’s manufacturing facilities are inspected by an independent body annual. These surveillance documents are reviewed by DIN CERTCO who has issued the KEYMARK to Studor for the Mini-Vent, Maxi-Vent and Trap-Vent.
The KEYMARK is a European quality mark and product certification scheme issued by the European Standard Organisation CEN (similar to the Kitemark issued in the UK by the BSI) and empowered by DIN CERTCO – the certification organisation of DIN, the German Institute for Standardisation. It proves that the Studor products fully comply with EN 12380:2002 through DIN CERTCO’s independent auditing and further reinforces the emphasis Studor places on quality, which fits in line with their mission statement to be the best quality product in the market place.
Relevance of the KEYMARK outside of Europe
As a European-wide accepted mark of quality with third-party validation, the KEYMARK is again of high importance for the international market. Some countries have already started to adopt European standards such as EN 12380:2002 as adequate replacement or guidance for their own national standards.
