Products: Pressure Relief Vent
Technical Standards/Schedules: ETS001
pressure relief vents through rigorous fire resistance testing and quality control audits with WarringtonFire.
压力平衡器为全淹没式气体灭火系统在灭火剂释放期间，为受保护区提供过压和欠压两种排气方式，在灭火气体释放完成后，于指定时间段内将灭火剂空气混合物保留在保护区内;过压时允许气体逸出，负压时允许气体进入保护区，使气体灭火系统更有效、更安全。
压力平衡器灭火系统EWCL5认证-Success with EWCL5 Certification on Pressure Relief Vents，泄压阀EWCL5认证通过严格的检测及质量控制审核，取得EWCL5认证。南京睿督公司为英国Warringtonfire实验室授权合作机构，专业提供英国UKAS资质的BS476检测认证，Certifire认证，WheelMark, ETA, TS19, TS30,EWCL5等认证。更多关于泄压阀EWCL5认证请咨询南京睿督工程师：025-8658 3475。
EWCL5-Certification
The EWCL5 scheme gives confidence to specifiers, enforcement authorities and building owners and occupiers that products provided by manufacturers are of the same specification as successfully tested/assessed.
The EWCL5 scheme requires manufacturers to produce products/systems to a successfully tested construction, the manufacture of which is regularly audited to ensure consistency of production.
The records of manufacture are kept and these are related to labels for each product available solely from Warringtonfire certification. Each label carries a unique number which is referenced back to the manufactured product enabling full traceability from the site back to the manufacturer''s records.
The scope of the certification is based upon the tested and assessed construction and enables the specifier or enforcement authority to check the suitability of a product for the intended end-use application.
Apreco has successfully retained our EWCL5 status on our pressure relief vents
Apreco continues to lead the way in the fire suppression market with annual testing of our pressure relief vents, ensuring the products we supply are always safe, compliant and fit for purpose. With the safety of building structures being of paramount importance to Apreco, we put our pressure relief vents through rigorous fire resistance testing and quality control audits with WarringtonFire.
We were the first manufacturer to obtain the EWCL5 certification following discussions with WarringtonFire around the need for tested products within the pressure vents market. At the time there was no harmonised code available for the fire testing of pressure relief vents, so we developed a test protocol in conjunction with the EWCL5.
As a result, our pressure vents undergo fire resistance testing under real-world scenarios. The scheme also follows annual Quality Management and Factory Product Control audits prior to sampling and testing. This ensures that the assembled product is the one that is tested. The records are then kept to support full traceability. This arms buyers and specifiers with confidence in our products and a performance that has been verified by experts in fire safety.
Within the global market, it is clear that certification for pressure relief vents has now become a necessary requirement. We are seeing too often, however, products on the market that have not been sufficiently tested and this is a very real concern for fire safety.
The IGV inert gas vent and the SGV halocarbon pressure relief vents are designed specifically over and under pressure venting associated with gaseous fire suppression systems used for fire protection.
The pressure relief vents can also provide protection against under-pressure characteristics found within synthetic/chemical suppressant systems. The IGV vents have the unique benefit of reversible flanges, allowing installers to alter the flow of direction configuration on-site, whilst keeping the units housed within the wall, avoiding protrusions and achieving a fire performance as detailed in our EWCL5 certificate.
