Updated Stipulated Standards & Requirements For Mechanical Self-closing Delayed-action Taps (Scdats) For Basin - Phasing Out Of SCDATS With Preset Flow Timing Of 2-3 Seconds
The Public Utilities Board (PUB) informed the industry on the updated stipulated standards for mechanical self-closing delayed action taps (SCDATs) for basin. Currently, mechanical SCDATs for basin shall be tested in accordance with Singapore Standard SS448:1998 and have a preset flow timing of 2 to 3 seconds. To facilitate handwashing for hygiene purpose in light of COVID-19, the preset flow timing for the mechanical SCDATs will be increased to 5 to 7 seconds, after taking into consideration overseas practices, local/overseas health authorities’ guidelines on handwashing, and the results from a local study on handwashing. The mechanical SCDATs with preset flow timing of 2 to 3 seconds will be phased-out by 31 August 2022. PUB strongly encourages Professional Engineers and Licensed Plumbers to use mechanical SCDATs with pre-set flow timing of 5 to 7 seconds for their new projects/premises with immediate effect. Suppliers are also strongly encouraged to upgrade their existing models or submit new models with new preset flow timing for WELS registrations. Please refer to the PUB’s circular here for more information on the implementation details and list of suppliers of mechanical SCDATs for basin.
