Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the re-drafting method to amend the use of international standards ISO 14409..2011 "ships and marine technology ships into the airbag." The technical differences between this and ISO 14409..2011 and the reasons are as follows. --- with our standard instead of some international standards; --- to change the note in 3.9 to be expressed in the text; an increase of 4.4, 4.5; re-arrangement ISO 14409..2011 Chapter 5 to Chapter 10 of the standard structure, modified the title to meet the standards of our standards; - The use temperature of the rubber material used for the balloon has a certain limit, so in Chapter 1, the airbag is added to the applicable environment Temperature range of content; --- Because our airbag products have "7 layer curtain fabric high bearing capacity airbag", and ISO 14409..2011 does not include the type, so In Chapter 4, the type and model of the airbag is added, and the corresponding size and compression are added in Chapter 5 Can parameter --- ISO 14409..2011 in the requirements of rubber materials, test methods and inspection rules as a whole, does not meet our Standard preparation provisions, so the part of the content split in Chapter 5 to Chapter 7, respectively; --- According to our factory inspection of airbags, including "material" inspection, and ISO 14409..2011 does not include the test items, because This adds the corresponding factory inspection items in 7.3.1. This standard is proposed by China Shipbuilding Industry Corporation. This standard is nationalized by the National Marine Ship Standardization Technical Committee (SAC/TC12). The main drafting unit of this standard. Jinan Changlin Air Container Factory Co., Ltd., China Shipbuilding Industry Comprehensive Technology and Economic Research Institute. The main drafters of this standard. Sun Juxiang, Gao Xuefeng, Huang Lizhen, Yu Bing, Wang Wei, Zhao Guangsheng, Wang Shaocing. Ships and maritime technology

1 Scope
