MOM

The Ministry of Manpower (MOM) of Singapore promulgated the Workplace Safety and Health Act (WSH Act) in 1996, which mandates that pressure vessels must pass third-party certification before use. The Act clearly states:

• Only inspection bodies that comply with the ISO/IEC 17020 standard are recognized to perform certification.

The certification scope covers the entire process of design, manufacture, and testing to eliminate the risk chain of ‘design defects - manufacturing violations - out-of-control use’.

1.Steam boilers (meeting all the following conditions)

• Using electricity as the only power source;
• Maximum steam volume less than 40 liters and safe working pressure less than 4 bar;
• Manual water addition is required at the start of steam generation, and continuous water supply from the drinking water main is not possible.

 2.Steam containers, air containers, pressure vessels, or refrigeration equipment

• Safe working pressure not exceeding 0.5 bar and volume less than 100 bar·liters (Note: pressure and volume product P×V < 100 bar·L).

• Certification basis:

Singapore's Workplace Safety and Health Act (WSH Act) and ISO/IEC 17020 inspection body accreditation standards.

• Service Scope:
• Compliance review of pressure vessel design documents (based on international specifications such as ASME, BS)
• On-site inspection of manufacturing processes (material verification, welding processes, non-destructive testing witnessing)
• Supervision of pressure tests (full witnessing of hydraulic/pneumatic tests)
