NSF-WRc는 많은 국가 및 국제표준에 대한 수도관 및 수도계량기 테스트를 위해 ISO 17025 인증을 받은 UKAS 인증기관이다. 연구소는 ISO 4064, EN 14154, OIML R49 등과 같은 국제표준을 인정받기 위해 25년 이상의 수도계량기 테스트 및 규격 경험을 보유하고 있다.

NSF-WRc의 시설은 새 수도계량기 디자인의 제품수명주기를 예측하기 위한 장기간의 서비스 상태를 모의 시험하는 테스트 장비의 내구성뿐만 아니라 물의 무게를 정확하게 측정하기 위해 중량 시스템을 최적화하는 유량시험장치를 포함한다.

 

 

 

NSF-WRc is UKAS accredited to ISO 17025 to test water fittings and materials to many national and international standards. The lab has over 25 years’ experience testing and calibrating water meters in domestic sizes to recognized international standards such as ISO 4064, EN 14154 and OIML R49. Part of NSF International’s global network of labs, NSF-WRc’s facilities include flow test rigs that utilize a gravimetric system to accurately weigh water as well as endurance testing equipment that simulates long-term service conditions to predict the life of new water meter designs.

 

The error determination tests can accommodate flow rates up to 120 liters/min (7 m3/hr) for water meters from 15 mm to 30 mm in diameter. Accurate water density measurement enables the precise calculation of the volume of water passed through the meter. NSF-WRc works with meter manufacturers, the water supply industry, government bodies such as OFWAT in the UK, private companies and individuals for meter trials, research and development work and failure investigations. The facility tests flow equipment in a range of operating conditions that affect water meter performance such as flow disturbance, magnetic field influence and temperature and pressure fluctuations. NSF-WRc conducts investigations of meters in dispute for water companies and their customers, as well as independent third-party failure analysis of water meters that have failed in service. NSF also has an office based in Abu Dhabi providing testing, certification, auditing and consulting for the water sector.
