1 Scope

GB/T 16956-2020 is the Chinese national standard on container lashing fitting for ships, 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 14 December 2020 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2021. Classification: ICS 47.020.50, CCS U24. 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 standard specifies the classification, parameters, main dimensions and marking examples, materials and requirements of marine container lashings (hereinafter referred to as lashings): Requirements, inspection and testing, inspection rules, marking, packaging, storage and transportation: This standard applies to the design, manufacture and inspection of lashings:
