ATEx Questions


My company has changed its name and address. What do I need to do in order that my ATEX approvals are up-to-date?
This type of change constitutes a variation to your certificate(s). You need to apply to CQST directly, ?explaining the change and attaching an updated label drawing.? CQST will connect the associate organization to re-issue your certificates with the new company name and/or address details. Your QA certificates will also require an update with the new details. The price for this service will depend on the number of certificates that require the change.
How much does an ATEX project cost?

Each product will be slightly different, and will require slightly different assessments along with the standard set of testing criteria that the relevant protection concept will dictate.
Complexity of design, the number of certification drawings and checklists you have and type of parameters you want for the project (i.e. Gas group, T-classes etc.) all have an effect on the scope of work, and hence the cost.
Ex ia projects will generally cost more than Ex d or Ex e projects, for example, as they have a more complex scope and will require more assessment.
CQST can issue fixed priced quotations specific to your product and scope of work. We can also offer more general budgetary quotations to give you an idea of the costs of certification on receipt of product information.

To obtain a quotation, please provide us the product information (i.e. datasheets and drawings).

How long do ATEX projects generally take?
Project timescales will differ due to the scope of work involved, but generally an average timescale for an ATEX project is 6-8 weeks from start of project.
As with all certification bodies, we have a high volume of work, and lead-times to pick up projects do exist, however they vary on a daily basis. Generally we can start the project 1-2 weeks from acceptance of quotation and receipt of documents and samples.

It is important that we communicate regularly with you throughout the process, as delays in getting information to us (i.e. samples, revised certification drawings etc.) obviously affect the timescales. It helps to allocate a resource within your organisation dedicated to approval projects, so that we can set up a 'point-of-call' for any questions/requests we have throughout the project.
Also, some products might not comply first time round, so it may be prudent to see if our certification support services can help to reduce project timescales, by conducting an initial review of the product before embarking on any approvals process. Details of certification support can be found by contact us.

What content should a Declaration of Conformity contain?
The Declaration of conformity should include:
Name & address of the manufacturer (or their authorised representative).
A description of the equipment and its intended use.
All relevant provisions fulfilled by the directive (i.e. relevant product marking, T-class and gas groups).
Name & Address of the Notified Body who certified the equipment (if applicable).
Product Certificate Number (if applicable) i.e. SIRA06ATEX1234.
Reference to the harmonised standards used to certify the equipment.
Reference to other harmonised directives adhered to (if applicable).

(source: ATEX Guidelines. Please see section 10 of the ATEX Guidelines for more information)

For components (i.e. unfinished parts) an attestation of conformity is required and this must contain details of the characteristics of the component, how the component is to be incorporated into the finished equipment such that it will meet the provisions of the ATEX Directive.
As an end user, what documentation should I receive from a manufacturer/supplier of ATEX equipment?
Manufacturers/suppliers of ATEX equipment are obliged to deliver a copy of the Declaration of Conformity and a set of instructions for safe use relating to the product. It is also recommended that a copy of the ATEX certificate (if applicable) is also provided. Manufacturers are not obliged to provide a copy of the Technical File.
If you doní»t receive these things then the manufacturer/supplier is not fulfilling his responsibilities under the ATEX directive.
What mandatory markings do I need to put on my ATEX product label?

The guidelines set a minimum requirement for product marking. For information on this, please contact us.

I am a manufacturer of non-electrical equipment. What do I have to do to comply with the ATEX directive?

Manufacturers do not need to go through the EC Type examination route that electrical equipment is subjected to, unless the mechanical equipment is to be used in a zone 0 and 20 (category 1 equipment).
If the equipment is classified as category 2 equipment (for use in zone 1) then the manufacturer follows the process of í«Internal control of productioní» outlined in Annex VIII of the directive.
The manufacturer compiles a technical file of the equipment, and submits it to a Notified Body for them to store.
If the equipment is classified as category 3 equipment (for use in zone 2) then the manufacturer follows the process of í«Internal control of productioní» but does not need to submit the file to a Notified Body.
