 Malaysia DOSH certification

Introduction to DOSH certification

DOSH is the abbreviation of the Department of Occupational Safety and Health of Malaysia. All pressure-bearing equipment manufactured or imported in Malaysia must be certified by an authorized third-party inspection agency as the "inspection agency" of the Ministry of Occupational Safety and Health (DOSH).

Domestic manufacturers can design according to relevant standards of developed countries such as ASME standards or BSI standards (must be signed and approved by authorized overseas inspection agencies), but it is currently understood that it is difficult to pass DOSH approval for designs using national standards. The more common method is to convert the drawings calculated according to national standards into documents of A SME standards.
