Besa® safety valves are designed, manufactured and selected in accordance with the European Directives 2014/68/EU (New PED), 2014/34/EU (ATEX) and API 520 526 and 527.
Besa® products are also approved by RINA® (Besa is a recognized as manufacturer) and DNV GL®.
Upon request Besa offers full assistance for the performance of tests by the main bodies.
Here below you can find our main certifications obtained for the safety valves.
Certificates for safety valves
Besa safety valves are CE PED certified
The PED directive provides for the marking of pressure equipment and everything where the maximum allowable pressure (PS) is greater than 0.5 bar. This equipment must be sized according to:
- the fields of use (pressures, temperatures)
- the types of fluid used (water, gas, hydrocarbons, etc.)
- the size/pressure ratio required for the application
The aim of Directive 97/23/EC is to harmonise all legislation of the states belonging to the European Community on pressure equipment. In particular, the criteria for design, manufacture, control, testing and field of application are regulated. This allows the free circulation of pressure equipment and accessories.
The directive requires the compliance with the essential safety requirements to which the producer must conform the products and the production process. The manufacturer is obliged to estimate and minimise the risks of the product placed on the market.
The organization conducts audits and controls based on various levels of monitoring of the company’s quality systems. Then, the PED organization releases CE certificates for each type and model of product and, if necessary, also for final verification before commissioning.
The PED organization then proceeds with:
- The selection of models for certification/labelling
- The examination of the technical file and design documentation
- The definition of the inspections with the manufacturer
- The verification of these controls in service
- The body then issues the CE certificate and label for the manufactured product
Besa safety valves are CE ATEX certified
ATEX – Equipment for potentially explosive atmospheres (94/9/EC).
“Directive 94/9/EC, better known by the acronym ATEX, was implemented in Italy by Presidential Decree 126 of 23 March 1998 and applies to products intended for use in potentially explosive atmospheres. With the entry into force of the ATEX Directive, the standards previously in force were repealed and from 1 July 2003 it is prohibited to market products that do not comply with the new provisions.
Directive 94/9/EC is a ‘new approach’ directive which aims to allow the free movement of goods within the Community. This is achieved by harmonising legal safety requirements, following a risk-based approach. It also aims to eliminate or, at least, minimise the risks arising from the use of certain products in or in relation to a potentially explosive atmosphere. This
means that the likelihood of an explosive atmosphere arising must be considered not only on a “one-off” basis and from a static point of view, but all the operating conditions that may arise from the process must also be taken into account.
The Directive covers equipment, whether alone or combined, intended for installation in “zones” classified as hazardous; protective systems serving to stop or contain explosions; components and parts essential to the functioning of equipment or protective systems; and control and adjustment safety devices useful or necessary for the safe and reliable functioning of equipment or protective systems.
Among the innovative aspects of the Directive, which covers all explosion hazards of any kind (electrical and non-electrical), the following should be highlighted:
- The introduction of essential health and safety requirements.
- The applicability to both mining and surface materials.
- The classification of equipment into categories according to the type of protection provided.
- Production supervision based on company quality systems.
Directive 94/9/EC classifies equipment into two main groups:
- Group 1 (Category M1 and M2): equipment and protective systems intended for use in mines
- Group 2 (Category 1,2,3): Equipment and protective systems intended for use on the surface. (85% of industrial production)
The classification of the installation zone of the equipment will be the responsibility of the end user; therefore according to the risk area of the customer (e.g. zone 21 or zone 1) the manufacturer will have to supply equipment suitable for that zone.
Besa safety valves are RINA certified
RINA has been operating as an international certification body since 1989, as a direct consequence of its historic commitment to safeguarding the safety of human life at sea, safeguarding property and protecting the marine environment, in the interest of the community, as set out in its Statute, and transferring its experience, acquired over more than a century, to other fields. As an international certification institute, it is committed to safeguarding human life, property and the environment, in the interests of the community, and applying its centuries of experience to other fields.
Eurasian Conformity mark
The Eurasian Conformity mark (EAC, Russian: Евразийское соответствие (ЕАС)) is a certification mark to indicate products that conform to all technical regulations of the Eurasian Customs Union. It means that the EAC-marked products meet all requirements of the corresponding technical regulations and have passed all conformity assessment procedures.
