BS EN 14055 provides you with characteristics for type one products that include design and hydraulic and mechanical characteristics. BS EN 14055 also provides a test method for type one products.  

BS EN 14055 provides you with characteristics for type two products that include inlet valve, backflow prevention, marking of flushing cistern, warning pipe, overflow provision, flush volume, physical endurance, leakage of flushing device, chemical endurance of flushing device, and durability. BS EN 14055 provides a test method for type two products.  

BS EN 14055 provides you with characteristics and test methods for type three products. BS EN 14055 also provides assessment and verification of constancy of performance. BS EN 14055 helps you manufacture high-quality WC and urinal flushing cisterns.
