Foreword

The standard 3.2 and Chapter 4, are mandatory, the rest are recommended. This standard is based on the IMO SOLAS Convention (1974) and the 1978 Protocol and relevant amendments to the LSA (LSA) rule, MSC resolution MSC. 81 (70) life-saving equipment testing and MSC. 200 (80) life-saving equipment testing amendment, MSC. 201 (81) amendments to SOLAS, MSC. 207 (81) the relevant requirements of the LSA Code amendments subject to revisions. This standard replaces GB 4302-1984 "life preserver." This standard compared with GB 4302-1984, mainly for the following changes. --- Canceled wrapper lifebuoy relevant content; --- A new classification of the type of life buoy; --- Canceled lifebuoy materials physical chemistry performance indicators; --- Increasing the life preserver and attachments appearance, size, weight, materials and function test, and temperature cycling tests and drop tests conducted The modification; --- Increased inspection rules, given the type test and factory inspection inspection items, requirements and test methods for the table; --- Cancel the closed cell foam test method used lifebuoy. The standard proposed by China State Shipbuilding Corporation. This standard by the National Standardization Technical Committee loaded ship outfitting. This standard was drafted. Wuxi Xingtai ship equipment Ltd., Technical and Economic Research Institute of China Shipbuilding Industry. The main drafters of this standard. Huang Xian, package Guoping, Wang Lei, Zhao Hua, Gao Feng. This standard replaces the standards previously issued as follows. --- GB 4802-1984. Lifebuoy
