Certificates and Approvals Related to Pressure Transmitters
Pressure sensors have different approvals and certifications in terms of environmental, regional, and various applications. For example, some certificates like CE are used for trade in a specific region such as Europe, others such as ATEX for the use of sensors in hazardous and explosive areas, EHEDG for hygienic applications, and some are utilized in marine and shipbuilding industries. Some of these certificates will be explained in the following:
Pressure Transmitters Certificates
CE refers to the French “Conformite Europeenne” which indicates that the pressure sensor is designed in accordance with the EU standards of health, safety, and environmental requirements and is licensed for trade in the European Economic Area.
Manufacturers in the European Union (EU) and abroad for market and selling their products in European countries must produce their products in accordance with the applicable principles of the CE standard in order to receive the CE mark.
ATEX derives from its French name: ATmosphères EXplosibles is a European directive that addresses the requirements and regulations for the safety of electrical and mechanical equipment in hazardous areas (areas prone to explosion) in accordance with the EU / 94 / EC Directive.
If an electrical or electronic device is officially ATEX certified, it means that it has been fully tested and evaluated for work in hazardous and explosive environments. ATEX certification of products is compulsory for the equipment used in potentially hazardous areas in all EU member states.
International Electrotechnical Commission known as IEC is an organization that provides and publishes international standards for all electrical, electronic, and related equipment.
It is usually used to refer to one of the 13 power connectors defined by specification IEC 60320. Also, IEC relates more to the C13 and C14 connectors used by most computers and many AC-powered electronic instruments to connect the AC power.
IECEx stands for Certification by the International Commission on Electrotechnics for Explosive Atmospheres. To achieve IECEx certification, all products must be monitored through the International Electrotechnical Commission to ensure the required level of safety.
This process will determine whether the products can be used in hazardous areas or potentially explosives. This international certification facilitates international trade in equipment and services for use in explosive environments.
Underwriter Laboratories or UL for short Approve devices, systems, and materials based on industry standards to determine their relation to hazards to life and property, and issue standards and certifications.
This organization is responsible for testing products, devices, and systems safety and removing dangers of fire and electric shock caused by electric products with the goal of enhancing employee and consumer safety.
UL also sets standards for manufacturers that innovate new products. Electrical engineering, fire prevention, anti-theft and alarms, heating and air conditioning, injuries and chemical injuries, and shipping engineering are technical sectors related to UL standards.
UL certification involves listing certification and recognition certification. The Listing certification is generally associated with a final product, while the recognition certification is for the parts contained in a product.
SMC’s valves and switches are mainly parts that must be included in a product and are subject to the identification certification. The products that have UL certificates are given a CCN (category control number) based on the product classification.
A CCN, originally, contains four letters and a digit number. There are C-UL and C-UL-US variations of UL's Listing mark: C-UL mark means conformity to CSA standards. CSA standard The United States and Canada provide a Mutual Recognition Agreement (MRA) for the recognition of certifications by the other.
When a product is approved by UL according to Canadian standards (CSA standards), the certification mark for the said product will be the C-UL mark which means conformity to CSA standards and has been evaluated to Canadian safety requirements. C-UL-US The optional C-UL-US mark indicates that the product was tested by UL and is in conformity with both Canadian and U.S. requirements.
FDA stands for Food and Drug Administration and this organization is a subsidiary of the United States Department of Health and is responsible for examining the status of all products.
This certificate is the recognition of the manufacturing company by the FDA regarding the hygiene of the company's products and also is the order to import the products of that company.
The FDA's export certification presents the agency's official confirmation about the status of the agency's oversight or product marketing, according to the information available at the time of issuance of the FDA certificate (including, if necessary, certificates offered by the applicant). Any manufacturer wishing to export such products to the United States or import them must obtain a set of related FDA licenses and approvals.
EHEDG stands for the European Hygienic Engineering & Design Group and has developed standards and techniques for checking and certifying devices according to the latest research and latest technologies.
It provides guidelines to make sure high-quality production and processing equipment for the safety of all food products.
EHEDG laboratories are allowed to perform extensive testing related to sanitary engineering and offer standards and requirements for devices used in food production and processing. It helps minimize food safety risks through high-quality devices and reduces cleaning costs with clean-in-place (CIP) technology.
