New guideline for product safety requirements in Singapore

Singapore, officially the Republic of Singapore, is an island country and city-state in South East Asia, with Malaysia to the north and Indonesia to the South. The population is presently about 6 mill, with ¾ being of Chinese descent.

On 1 February, the country’s Consumer Product Safety Office (CPSO) published an updated Information Booklet for Product Safety Requirement Regulation.

 Among the updates are the below items related to IT/AV products.

- Circuit diagrams shall show components’ values for products tested to IEC60065, IEC60950-1 and IEC 62368-1.
- Electric appliances with maximum rating above 3 kW shall have fixed wiring. (Rating based on supplier’s declared output or on test results, 
  whichever is higher).
- AC adaptors with output >100W shall comply with the requirements in circular CPSO-070923-11 (Appendix I)

Additional details from circular CPSO-070923-11:

A. For AC adaptors tested to IEC 62368-1 edition 3.0 (2018) and earlier:
    a. Clause 6.6. of Ed.3.0 only allows for AC adaptors delivering >100W to a connected equipment if the connected equipment also complies with
         IEC 62368-1. 
    b. The circular describes in detail the methods to fulfill the Clause 6.6.

B. Requirements for AC adaptors tested to IEC 62368-1 edition 4.0 (2023) 
     a. Clause 6.6. of Ed. 4.0 allows for AC adaptors delivering >100W to a connected equipment if power is not delivered via a communication port.
     b. AC adaptors delivering >100W to a connected equipment are unlikely to deliver power via a communication port. Hence, most such AC 
        adaptors will fully comply with Ed. 4.0 without needing further requirements.
