MOM is an abbreviation of the Ministry of Manpower in Singapore. All pressure-bearing equipment manufactured or imported for use in Singapore is certified by an authorized third-party inspection agency as the "inspection agency" of the Ministry of Occupational Safety and Health(MOM) for the design, manufacturing and inspection process.
Domestic manufacturers can design according to relevant standards in developed countries such as ASME specifications or EN standards(which must be signed by overseas authorized inspection agencies), but it is currently understood that products designed using ASME standards are easier to pass MOM approval.
