1 Scope

GB/T 13414-2025 is the Chinese national standard on specification for marine exhaust gas boiler, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 August 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2026. Classification: ICS 47.020.20, CCS U 41. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the classification, requirements, inspection rules, marking, packaging, accompanying documents, transportation and Storage, etc., and describes the corresponding test and inspection methods. This document is applicable to steam boilers with a design pressure not exceeding

2.5 MPa and a working medium of water, as well as steam boilers with a working medium of water and an outlet temperature of Design, manufacture and acceptance of hot water boilers not exceeding 120°C.
