1 Scope

GB/T 16303-2024 is the Chinese national standard on ships and marine technology - launching appliances for free-fall lifeboats, 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 26 October 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 February 2025. Classification: ICS 47.020.50, CCS U27. 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 requirements, test methods, inspection specifications for free-fall lifeboat launching appliances (hereinafter referred to as free-fall appliances). regulations, labeling, packaging, transportation and storage. This document is applicable to the installation of free-fall lifeboat launching devices (including recovery devices) installed on ships or offshore platforms using inclined slides. Design, manufacture and acceptance of equipment).
