addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be  indicated if different from above:

4. Products covered (HS or CCCN  where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable): Mixing 
Taps and Valves. National tariff headings (HS): 8481.80.50  
5. Title, number of pages and language(s) of the notified document: Annex 1  - Draft 
Public Utilities (Water Supply) (Amendment) Regulations 2019 - Notice will be published 
in the Republic of Singapore 's Government Gazette when adopted. (1 page(s), in English)   
6. Description of content: From 1 April 2020 onwards, the prevailing test standard for 
thermostatic mixers under the mandatory Water Efficiency Labelling Scheme (WELS) will 
be replaced with Section 13.2 of the BS EN 1111 (2017). Suppliers registering new models 
of thermostatic mixers under the mandatory WELS are currently r equired to submit test 
results in accordance with section 10 of BS EN 1287 (1999). To allow suppliers and test 
laboratories to prepare for the new test standard, there will be a transition period from 
1 April 2019 to 31 March 2020, during which suppliers can submit test reports based on 
either section 10 of BS EN 1287 (1999) or section 13.2 of BS EN 1111 (2017) to register 
their new thermostatic mixer models. All existing thermostatic mixer models which a re 
registered under WELS before 1 April 2020 can still continue to be supplied without having 
to re-submit test results.  
7. Objective and rationale, including the nature of urgent problems where 
applicable: Background: The mandatory WELS for water fitting s was introduced in 
Singapore on 1 July 2009. Under the scheme, all water fittings, including thermostatic 
mixers, must be registered and labelled to provide information on their water efficiency 
level before they can be sold or supplied in Singapore.  
From 1 April 2020 onwards, the prevailing test standard, i.e. section 10 of BS EN 1287 
(1999), will be replaced with section 13.2 of the BS EN 1111 (2017), which is designed 
to test mixers that operate at pressure conditions more relevant to Singapore 's water 
network. This will tighten performance requirements for thermostatic mixers, leading to 
increased product safety. With this change, suppliers who have already tested their 
thermostatic mixer models to BS EN 1111 (2017) will not need to retest their product s to 
BS EN 1287 (1999) when registering their thermostatic mixer models with PUB.
