The word certification comes from joining together two Latin words, ?certe? (meaning certain) and ?facere? (to make). Certification describes the common practice with which the fulfilment and compliance with certain standards or requirements should be realised and verified.
As a rule, products, services, processes. persons and also systems could be certified. Usually, the certifications and the conformity assessments they are based upon are carried out by independent certification bodies. With the certification for fire-protection applications, the next three certification bodies and acceptance marks have been established.
Leading certification bodies for fire-protection application
VdS ? Schadenverh�tung GmbH
VdS, using its headquarters in Cologne, is today the most renowned institutions for corporate safety, with a focus on fire protection, security and natural hazard prevention. On the list of services that the company offers, in addition to the certification of products, may also be risk assessment, testing of equipment and an easy educational offering. Particularly in fire protection, the VdS press enjoys a fantastic reputation and is necessary on all equipment used within fire protection within German-speaking countries. Because the basis for being marked with the VdS press, there is an acceptance procedure using the applicable DIN, EN and ISO standards along with VdS?s own guidelines.
LPCB ? Loss Prevention Certification Board
LOSING Prevention Certification Board is a portion of the BRE (Building Research Establishment) Group. The BRE Group focuses on research, consultancy and testing in the building industry. Amongst their services are also certifications and acceptances, among others, in the field of fire protection and safety. These certifications beneath the marking and logo of the LPCB are mostly important in the uk, the center East and the Asia-Pacific region. Just as with the VdS, the LPCB uses EN and ISO standards together with their very own guidelines as a basis for certification. Meanwhile, there exists a cooperation between VdS and the LPCB with the purpose of recognising the prevailing certifications and testing and therefore to simplify also to increase the certification process.
UL ? Underwriters Laboratories
Underwriters Laboratories ? founded in 1894 ? is really a US-American product certifier. Unlike the VdS or the LPCB, their certifications not merely extend to the construction, fire protection and safety industries, but rather across a much wider spectrum. This spectrum covers, for instance, standards for refrigeration plants, lithium batteries, ice machines, cabling, ? . Especially within the American market, where VdS and LPCB are not represented, UL approval is specially important. However, also in the Middle East and the Asia region, UL certification for fire-protection applications plays a major role.
The acceptance procedure
Typically, the acceptance procedure is triggered with the relevant certification body by the manufacturer or the provider of the services. First, the applicant must submit the corresponding product or project documentation for testing by the certification body. The notified body then develops a test plan in line with the national or international standards to be used and the guidelines of the certification body itself. In the case of pressure measuring instruments and pressure switches for use in fire protection, DIN EN 12094 ? 10, for example, which controls the testing and requirements for components, can be used as a basis. Cheat contained within this should ensure that certain requirements of the standards and guidelines are fulfilled. Thus, amongst others, functional testing, temperature testing and in addition even corrosion testing within an atmosphere of sulphur dioxide are completed.
A confident test report is imperative for gaining the certification. After that, confirmation of conformity follows with the issuance of the certificate. With the issuing of the certificate, the product or service may carry the acceptance marking. Usually, the certificate will be provided with a validity duration of a few years. Even with the issuance of the certificate, during the complete validity duration, product monitoring measures, such as regular production audits and product inspections are required. Both the acceptance procedures plus the subsequent monitoring measures have become costly, however, the holder of the marking also has extensive marketing opportunities and competitive Advantages.
Conclusion
Certification for fire-protection applications is dominated by the three largest acceptance marks of VdS, LPCB and UL. Virtually no extinguishing system comes without certification. Accordingly, the use of certified components also simplifies the building and approval processes of the OEMs. Therefore, WIKA also offers pressure gauges and components which are already approved.
Note
WIKA offers both approved pressure gauges and approved components for fire-protection applications. For example, the model 111.12.040 pressure gauge as well as the model PGS11.040 and model PGS21.050 pressure gauges with switch contacts are approved relative to VdS and also LPCB as instruments for used in fire-extinguishing systems. Thus, WIKA is the only manufacturer worldwide which includes VdS and also LPCB approved pressure gauges and in addition pressure gauges with switch contacts in its product programme. In addition, the instruments are also suitable for used in fire-extinguishing systems with UL marking. In case you have any more questions, your contact person will be at your disposal.
