The ASME boiler standard of the American Society of Mechanical Engineers is an internationally recognized authoritative boiler regulation and is widely used. Holding the ASME certificate is also a strong proof that an enterprise's management and technology have reached the international level. In 2007, ZOZEN took the lead in obtaining the ASME stamp and authorization certificate in the industry, taking a big step towards the international market.
