Definition of MOM
Conformity assessment by a designated, notified body must be performed prior to importing boilers and pressure vessels to Singapore. Devices for installation in Singapore need approval for installation through a registration process. The fabrication survey report, which is one of the requirements for registration, can only be acquired through the MOM certification.
