Legend
UR: only UR (Recognised)
Ex: products are also Ex-approved
◻ Planned
National approvals
UL, UR: Underwriters Laboratories is an independent organisation with headquarters in the USA that inspects and certifies products with respect to their safety.
- UL (Listed) = certified device
- UR (Recognized) = certified component
cULus, cURus: Certified according to US and Canadian requirements by Underwriter Laboratories. The UL basically also checks the Canadian standards. In the future this approval will replace the UL, UR and CSA at Bürkert.
The Canadian Standard Organisation is the authoritative body for national standardisation in Canada. Only products that are tested and certified according to the relevant standard may bear the CSA mark. There are several parallels to the UL certification in the US.
The Canadian Registration Number is issued for products that include the print policies of the individual Canadian provinces with respect to the durability of the housing.
The Pressure Equipment Directive is a Directive of the European Parliament and establishes the requirements of pressure devices for the introduction of pressure devices into the EU market.
The EAC mark is the conformation that a product has undergone a conformity procedure and satisfies the technical requirements prescribed there (Eurasian Conformity). It applies for the introduction of products into the markets of Russia, Kazakhstan and Belarus. The certificate is issued by an authorised certification authority.
Explosion protection
IECEx Cat. 2: IECEx covers devices and protective systems that will be used in explosion-prone areas (international). The approval is national law in Australia and New Zealand only; however, it is often recognised and taken as a basis for national Ex approvals ( China, Japan, Korea, Brazil, etc.). The requirements originate from the IEC 60079 series of standards.
ATEX, Cat. 2: ATEX covers devices and protective systems that will be used in explosion-prone areas (Europe). Directive 2014/34/EU specifies the requirements. In order to fulfil the requirements of the Directive, harmonised standards are applied (EN 60079-x series). It is assumed that when the standards are fulfilled, the requirements of the Directive are also fulfilled.
UL HazLoc Div. 2 coil: This approval certifies products for use in explosion-prone areas and is recognised in the entire North American sphere. At Bürkert this approval will replace FM and CSAEx in the future.
FM Hazloc Div. 1 coil: This Approval certifies products for use in explosion-prone areas and is recognised in the entire North American sphere.
KOSHA: Safety components, pressure containers and products for the Ex area must be approved by KOSHA in South Korea. An IECEx approval can serve as a basis, but national testing criteria can be added.
NEPSI: Explosion-protected electrical operating equipment are tested and certified by NEPSI in China. An IECEx approval can serve as a basis, but national testing criteria can be added.
Water
ACS: The ACS approval is a hygienic inspection of wetted materials and is mandatory in France. Without the ACS approval of materials or other components for potable water applications, this market remains closed to the product.
The KTW guideline is the approval of plastics and other nonmetallic materials (e.g. sealing materials) for use with potable water in Germany. Manufactured components are tested according to KTW requirements and the base material is tested according to DVGW worksheet W270.
VDE: VDE (Association for Electrical, Electronic & Information Technologies) certifies valves in accordance with EN 60730. In addition to the functionality, the safety requirements of products are tested.
WRAS: Products and materials with a WRAS approval comply with the requirements specified by the responsible water supply by, for instance, not contaminating the water. This approval is recognised in the United Kingdom.
Gas
AGA: The Australian Gas Association tests and certifies products and machines from the gas, electrical and sanitation areas. The certificates are exclusively approved for the Australian market.
CSA Gas: The CSA Gas approval applies for the Canadian sphere. It is comparable with the AGA certificate in Australia and serves as a basis for the use of a gas solenoid valve in Canada.
DVGW Gas: DVGW CERT GmbH is a European certification authority in gas and water applications. Together with its test laboratories, it tests, certifies and monitors technical products for gas and water, quality systems and environmental management systems in accordance with DIN EN ISO 9000 ff . and DIN EN ISO 14001 as well as companies and individual persons (qualified experts).
Hygienic
EC 1935/2004: The European regulation specifies uniform regulations for materials and objects that come or could come into direct contact with foods. The aim is to protect human health and consumer interests.
Application-specific approvals
DNV GL: In 2014 GL and DNV merged to create the DNV GL Group. DNV GL is the world’s largest shipping and off shore classification organisation and is a consultant for the oil and gas industry. It offers consulting in the value creation chain in the energy sector. With the goal to protect lives, property and the environment, DNV GL improves the safety and sustainability of various products.
DIN EN 45545 places high demands on the fire protection of installed components and materials within a railway vehicle. The products are classified according to different fire classes. The classification is certified in a conformity process.
SIL: The safety requirement level is not an approval, rather a term from the area of functional safety and is also identified as Safety Integrity Level (SIL) in international standardisation according to IEC 61508/IEC 61511. It serves for the evaluation of electrical, electronic and programmable electronic (E/E/PE) systems in regard to the reliability of safety functions. The safety-related design principles that must be complied with in order to minimise the risk of a malfunction are specified by the desired level.
Machinery Directive: The Machinery Directive (Directive 2006/42/EC) regulates a uniform level of protection for accident prevention for machinery and machine components for introduction to the market within the European Economic Area (EEA), as well as Switzerland and Turkey.
