Mandatory Water Efficiency Labeling Scheme (MWELS) for Washing Machine Testing

STS conducts water efficiency testing on washing machine to Public Utilities Board of Singapore (PUB) requirements.

Upon testing, STS assist the manufacturers and traders to apply for PUB Water Efficiency Labels.

Upon successful registration with PUB, suppliers/retailers will fix the Water Efficiency label for each of their washing machine model displayed for sale or supply. The Water Efficiency label will also be prominently fixed to each model or on its packaging at the point of sale or supply or offer for sale or supply.
