All products delivered by ASCO are in conformity with the new and updated directives and standards, including the new ATEX Directive 2014/34/EU (since the 20th of April 2016). Previously this was the Directive ATEX 94/9/EC .
What equipment has to comply with ATEX for use in hazardous areas?
The ATEX Directive applies to electrical and non-electrical equipment.
For a solenoid valve, it is the complete product comprising the electrical operator and the valve which must be ATEX-certified.
For an electro-pneumatic valve with integrated pilot, it is considered similar to solenoid valve, so the whole product must be ATEX-certified.
For an electro-pneumatic valve with a separate CNOMO solenoid pilot, 2 certifications are necessary, one for the solenoid operator and one for the pneumatic valve. The reason for this is because each product can be used alone.
ATEX certification is also necessary for non-electrical equipment such as regulators, valves, cylinders, etc, if used in a certified zone.
ATEX certification is not necessary for non-electrical equipment that does not have its own potential ignition source, such as filters, lubricators, etc. These product categories are named simple mechanical products and can be used in specific ATEX zones 1, 2, 21 and 22 in compliance with the manufacturer's instructions.
What is the new ATEX Directive 2014/34/EU and when does it take effect?
The European Commission has introduced updates to the legislative framework of several of its European directives. The objective is to improve the directives and therefore the safety of the products they apply to, and to reach a level of higher protection for the customers.
As per the 20th of April 2016, Directive 94/9/CE has been replaced with Directive 2014/24/EU. The changeover date was fixed and there is no transition period.
Existing ATEX certificates issued following the directive 94/9/CE remain valid
No technical change
Issuance of certificates following the directive 2014/34/EU for new products or if modified certified product after April the 20th 2016
New EU declaration of conformity accompanying the product versus older CE declaration of conformity is required on factory shipped product on April the 20th 2016
From which date a manufacturer has to mention the new ATEX Directive for his EU declaration of conformity?
Before 20 April 2016 all the EC declarations of conformity for ATEX products placed on the EU market for the first time must be in line with Directive 94/9/EC. Products that are already in the distribution chain (including stockpiles), before 20 April 2016, can continue to be distributed with the EC declaration of conformity referring to Directive 94/9/EC, as they have already been lawfully placed on the EU market. Declarations of conformity (EC or EU) remain valid according to the legislation in force when the product is placed on the EU market (= made available on the EU market for the first time). There is no need to change legislative references in documents accompanying the product.
For products placed on the EU market as of 20 April 2016 (or, in the case of products manufactured for own use, put into service), the EU declaration of conformity must be in accordance with the new ATEX Directive 2014/34/EU.
Will certificates issued in accordance with Directive 94/9/EC still be valid after 20 April 2016?
Yes. Certificates issued under Directive 94/9/EC (in particular EC-type examination certificates or quality assurance certificates issued by notified bodies) until 19 April 2016 will remain valid under Directive 2014/34/EU until their fixed expiration date. Certificates issued according to Directive 94/9/EC can still be used for EU declarations of conformity according to Directive 2014/34/EU.
Under the new ATEX Directive 2014/34/EU, what happens to the distributors and users' material in stock (declared to 94/9/EC only)?
A product must meet the legal requirements during its initial placing on the market. The distributor or user's stocked product is already considered as placed on the market before the 20th of April 2016: the 2014/34/EU directive does not apply.
Which is the difference between "making available on the market" and "placing on the market" in the framework of Directive 2014/34/EU?
"Making available on the market" is the overall concept. Any transfer between economic operators of a product is considered as making available. "Placing on the market" is a specific case of making available, namely it is the first time that the product is introduced on the market. It is important because at that moment the EU legislation applies. Any subsequent transfer is a "making available".
The operation is reserved either for a manufacturer or an importer, i.e. the manufacturer and the importer are the only economic operators who place products on the market. When a manufacturer or an importer supplies a product to a distributor or an end-user for the first time, that operation is labelled in legal terms as placing on the market. Any subsequent operation, for instance, from a distributor to another or to an end-user is defined as making available.
Can I mount accessories on the ATEX-certified products?
contact us for a list of all compatible accessories which have been the subject of risk analysis. For all other accessories, risk analysis must be performed on a case-by-case basis.
Can I assemble ATEX-certified products?
Yes. For example, a pneumatic valve and a CNOMO interface solenoid valve, a cylinder and an electro-pneumatic valve... as long as the following rules are respected:
Check the continuity of the earth connection to allow dissipation of static electricity. This continuity must be ensured on all equipment requiring assembly, whatever the area of use.
Traceability of ATEX products:
Traceability of ATEX products is mandatory from their manufacture through to their use. ASCO archives information such as customer identification, product code, serial number, date of manufacture and order number.
I want to replace non-ATEX equipment certified according to the previous method on an existing installation. What should I do?
We advise you to replace the old products with ATEX-certified equipment.
Can I repair ATEX equipment?
You can buy spare parts kits for ATEX products and carry out maintenance subject to some conditions:
You must comply with instructions contained in the installation and start-up guide delivered in the spare parts kit.
You must ensure traceability of the repaired ATEX product.
The technician performing the repair must have received sufficient training concerning the ATEX directive and the risks of explosion.
The conformity of the markings must be checked (manufacturer's markings, modification/repair markings).
You must change the existing ATEX label:
